huhhhhhhhhh!!! ganoon ba?? akala ko kaya sinapamal yung bata dahil pangit at mukhang ungguy.. ay yun pala para makahinga ng oxygen sa air for the first time.. he heh e..joke lang po!!! Do they know that babies up to six month know how to swim, they can go under water and float again? Also Scientists said it’s because we still adapt to live in water for 9 months, should I say more.. eh ang lahi natin nanggaling sa tubig.. he he he.. , no wonder you like salty food, kiddoss!! he heh e.. hoy kasama sa science iyan. and It's becuase their lung's is not fully developed before 6 months, they have the ability to shut it off and expel the water that they drink. uppsss, teka , ano ba ang mechanism ng gills ng mga isda? the water goes into their mouth, and the gills extracts or take the oxygen from the water, (remember, 2 elements of water= h20, hydrogen and oxygen) but instead of going out in their mouth again, it goes out to their gills. coooooolll!!! he he he!!! and here’s another one… natatandaan ba ninyo kapag masakit ang tiyan ninyo, ang sabi, ang sakit ng appendix ninyo, eto ang totoong myth.. he hehe.. did you know that it has no use to us. We still have some organs that has no use to us, since our diet had changed, e.g. natuto tayong magluto, and eat foods that are easy to digest, overtime, our appendix is not being used, but it’s still part of human organ. Some animals have 2 or three actually, it function as extra mechanism in their digestion . like cows , if i'm correct ( will search which animal is that later), they chew the grass, then they will bring it up again i their mouth for more chewing, ayyyyyy kadiri..he hehe.. they need this kind of system to facilate the kind of diet that they adapt. here it is.. appendix A small saclike organ located at the upper end of the large in-*test*-('")ine. The appendix has no known function in present-day humans, but it may have played a role in the digestive system in humans of earlier times. The appendix is also called the vermiform appendix because of its wormlike (“vermiform”) shape.

Para naming eblog ko yata itong thread!! he he he!! I should create my eblog din, but I who would be interested to read my stuff, at least here, I have the chance to be heard and to listen. Whaddaaahh.. You might read recapitulation theory by Haeckel’s in many Christian site, they claim it’s deceitful and fraudulent. I did some investigations, it’s another bogus from Christian sites, be careful guys. I think Haeckel’s theory is the next best to Darwin’s when I first read it, I supposed, we are not all perfect. You will see this kind of propaganda in many christian sites, I let you be the judge. The Recapitulation Theory The "Embryonic recapitulation" theory was disproved decades ago, yet some uninformed people are unaware it has been debunked and are still teaching it. This theory says that the human fetus goes through various evolutionary stages in the mother's womb. Some people wrongly believe that the human fetus in its early stages has "gill slits" like a fish and a "tail" like a monkey. This is supposed proof that humans show signs of going through the evolutionary process of development. However the "gill slits" are folds, or wrinkles. In fish, the gills are designed for water to flow through to extract oxygen from the water. However, these folds in humans develop into the tonsils, ear canals, parathyroid and thymus glands. They only appear to be gill slits. Only a prejudiced mind would call them gills because they look like fish gills. The "tail" isn't a tail but the end of the spine. The tip end is called the coccyx and sticks out because it is the first to develop. Although evolutionists no longer accept the recapitulation theory, many people at one time believed this was proof for evolution. Even today some people promote this theory, not realizing it was disproved long ago. http://www.odsgc.net/~cornerst/biblestudies/recapitulation.htm I check encyclopedia britannica, and other gov and educational site, it has the same explanation... more on this later. here's one from wikepedia. recapitulation theory Ontogeny recapitulates phylogeny, also called the biogenetic law or the theory of recapitulation, is a hypothesis in biology first espoused in 1866 by the German zoologist Ernst Haeckel, a contemporary of Charles Darwin, which has been discredited in its absolute form, although recognised as being partly accurate. In biology, ontogeny is the embryonal development process of a certain species, and phylogeny a species' evolutionary history. Observers have noted various connections between phylogeny and ontogeny, explained them with evolutionary theory and taken them as supporting evidence for that theory Haeckel's theory Ernst Haeckel's embryo drawings.Ontogeny is the development of the embryos of a given species; phylogeny is the evolutionary history of a species. The theory claims that the development of the embryo of every species repeats the evolutionary development of that species fully. Or otherwise put: each successive stage in the development of an individual represents one of the adult forms that appeared in its evolutionary history. Haeckel formulated his theory as such: "Ontogeny recapitulates phylogeny". This notion later became simply known as recapitulation. In order to support his theory, Haeckel produced several embryo drawings which overemphasized similarities between embryos of related species and found their way into many biology textbooks. http://www.answers.com/main/ntquery?method=4&dsid=2222&dekey=Recapitulation+theory&gwp=11&curtab=2222_1&linktext=recapitulation%20theory

ay naku.. why don't they leave it to the scientists who dedicated their lives to this field. this was prepare by THE NORTH CAROLINA ACADEMY OF SCIENCE in defence of Earnts Haekel’s work. PART II. NC SCIENTISTS ADDRESS SOME CREATIONIST ARGUMENTS Ernst Haeckl was a great German embryologist who was instantly excited about the theory of evolution when Darwin's book was first published. The reason he was so excited is that evolution explained what Haeckl had been observing for years - that because of common descent, there are great similarities between the embryos of all vertebrates, and that many structures, like the gill slits, which have known functions in ancestral forms (fish), are also found in descendants (land vertebrates). Why on earth should land vertebrates like mammals have gill slits during development? Haeckl recognized that these are retained from the ancestor. Unfortunately, in his zeal to show the many ways in which ontogeny (development) recapitulates phylogeny (evolutionary history), Haeckl went too far. He misinterpreted the evidence and thought that adult ancestral structure was passed on to embryos of descendants - that, in fact,. functional gills developed while a mammal embryo was in utero, and that later in development the gills were modified into mammalian structures. http://www2.ncsu.edu:8010/ncas/evolution/#C.%20GILL%20SLITS ayun naman pala eh.. so it was not completely wrong, that's why it was not accepted in 19th century. There were many theories that had been altered or removed if new evidence was ever found out that could refute them, and now it was corrected and that theory became now called Biogenesis. In our biology textbooks that's being used at school says, (eg. those pictures are from univesities site) all mammals have gill slits during their development, But IT IS NOT FUNCTIONAL, as earlier mentioned, that is the key word that has been corrected and replaced. at saka, why the Christian church question human embryo gill slits is not what science have proven to be true? In embryology- all mammals on their early development have gill slits, and what made human embryo exempted naman, eh mammals din tayo diba? he he he!!! here’ another piece of work of someone's an investigations if there’s such an event that Haeckl was charged of fraud… good investigations and great sources. ‘At Jena, the university where he taught, Haeckel was charged with fraud by five professors and convicted by a university court.’ In actual fact there is no evidence that Haeckel was even tried – much less convicted of fraud. This is a very common creationist misnomer and some prominent scientists – such as Michael Richardson, who has studied Haeckel’s work thoroughly – have been fooled by it. Richardson made the same claim after reading this story in a newspaper. Shortly after, two scientists from Germany (Sander-K, Bender-R. Science. 1998. 281:349) wrote a letter to the prominent journal Science: Every sort of vilifying argument was welcome . This seems to still be true today, as is evidence from recent claims in the British Press that Haeckel had been convicted by his university of alleged fraud. On being asked to disclose their sources, one of the respective authors kindly referred us to a book agitating against the origin of man from other primates (which in turn gave no relevant reference), while the other did not answer our queries. Because, to our knowledge, no respectable historical source mentions this conviction of Haeckel, we conclude that the claim for it must be based on hearsay, not fact.’ http://www.geocities.com/a_and_e_uk/PerloffC10.htm oo nga naman, science will only disprove any theory that may arise, and then if new evidence has found, it must be removed or alter in our book of knowledge, eh bakit naman nila, I-charge si Haeckl, anong fraud naman, anyone can write a book, but the end product was decided by science community. At bakit siya ba ang ma control ng mga Books ng biology? he he he.. actually, his work has reach our biology book and being taught along with evolution.

you can also read in some christian sites claimed that no embryologists/scientists had ever accepted that human embryo actually had gills/gill slits, they missed the most important fact and forget to mentioned, whether it is "functional/not functional". The same concept that they claimed that Entropy violates the Law of thermodynamics, he hehe, they used earth as an example, bad bad bad science, earth doesn't play an example of a "CLOSED SYSTEM", they missed most important points again, that it is an "open system". A good example of a closed system is a battery, where it deteriorate becuase it has no source of energy after it has been used. We continiously get energy from the sun. They want to disprove that we do not came from simple to complex, rather we started from complex to simple to deterioration.. he he he! here's my share of investigation !!! nagpapaalala lang...he he he he.. it's best post this pic again, edited!!! pic from Lewis & Clark College, Portland Oregon below is from The College of Sciences, San Diego State University... http://www.sci.sdsu.edu/classes/biology/ LECTURE 12: EVIDENCE FOR EVOLUTION ...................a. embryonic development -- different species go through similar stages of embryonic development -- for example, all vertebrate embryos have gill slits on either side of the throat -- develop into gills in fish, but develop into other structures in terrestrial vertebrates -- suggests that all vertebrates are related and descended from a common ancestor that had gills. http://www.sci.sdsu.edu/classes/biology/bio100/truesdale/Lectures/Lect13/lect13.html LECTURE 12: EVIDENCE FOR EVOLUTION

^^^^^^^^^^^^^^continuation, more from UNI's .... sorry guys if you see some of my entries has been edited a few times, sometimes I cut it short and place it as a new post reply, or i added more info, pictures, then typos, grammar, spelling correction... etc.. he he he.. bawal na yun dito??? -------------------- too many scientific terms to know... ayyyy... he he he from Indiana University.... Chordates All organisms that belong to phylum Chordata possess bilateral symmetry, a post-anal tail, gill slits, a notochord and a hollow dorsal nerve tube at some time during their life. They may not have all of these features all of the time. For example, a mammal has gill slits while it is an embryo but loses those gill slits prior to birth. A human no longer has a tail. The "tail bone" remains even though it is not visible from the outside of the organism. While vertebrate animals (that is, animals that possess a backbone) are all chordates, not all chordates are actually vertebrates. The tunicates below begin life looking something like a small fish or tadpole and have a notochord but later change into the invertebrate blob you see. http://www.indiana.edu/~q201bio/labs/lab5/chordata.htm how about .. we just ask the scientist... he heh e!! From University of Chicago Newton BBS Ask A Scientist© Zoology Archive Gill Slits in Humans name Darren status other age 30s Question - Is it true that babies can be born with a congenital throwback i.e. born with fish gill/s and if so what is it called? All mammals have gill slits in their very early fetal development. We call this ontogeny recapitulating phylogeny..where the development of the individual goes through some of the characteristics of the animals lower in the evolutional development. When we look at early fetal development of various animals we see all having gill slits, and tails. http://www.newton.dep.anl.gov/askasci/zoo00/zoo00105.htm from the same university, Ask A Scientist© Molecular Biology Archive Human Embryo and Tails name Karl S. status other age 20s Question - I read the following question and answer from your web site, and I understand the explaination of recapitulating phylogeny, but is it actually possible for babies to be born with either something resembling "gill slits" or a "tail"? Possibly flaps of skin or an elongated tail bone? Question - Is it true that babies can be born with a congenital throwback i.e. born with fish gill/s and if so what is it called? ------------------------------------------------ All mammals seemingly have gill slits in their very early embryo development. We call this ontogeny recapitulating phylogeny..where the development of the individual goes through some of the characteristics of the animals lower in the evolutionary development. When we look at early fetal development of various animals we see all having gill slits, and tails. Your questions involves very complex answers, but I will address some aspects of what you ask. Yes, there are people born with tail-like fragments or protrusions of the spinal column, that are removed or reinserted at birth. Though I have seen this in some medical journal, it is so rare that I have had nurses question the whole idea. These "tails" are usually not substantial in structure and certainly do not take on a look of a monkey tail, etc. As a matter of fact, they may not be a tail per sa. I questioned this idea for a long time until I found a friend that was born with a very small protrusions of sorts. Whether it was a tail, is probably a matter of semantics. I do not recall a name for this phenomenon. If the gill-like slits did remain, the fetus would probably be naturally aborted at a very young embryonic stage. The complex feedback system of embryo development requires a successful step by step process. The human genome project will probably address this or other past characteristics eventually. Humans have a tremendous number of introns (I believe in chromosome 20 alone, there are 164 of these-source "Nature" (Dec. 2001 issue ?).It seems that much of our unused DNA is coded for our evolutionary past, but this is not clear at this writing. It is very clear that we are a product of evolutionary development and we are the threshold of understanding all of this better thanks to DNA analysis studies and related techniques. Keep your eye out for further developments and explanations. Steve Sample ========================================================= http://www.newton.dep.anl.gov/askasci/mole00/mole00114.htm

Upppssss.. oo nga pala, I said I will check that animal on my previous post here about that have extra stomach, this is related to non functional human oragan, our appendix..... medyo wala sa topic, pasensiya na... yeahhh, it is cows that have 3 stomach according to my hubby. I mentioned befpre that we still have some organs that are not functional, wonder why? New kinds of Human only developed to eat cook/ easy to eat food in over how many million of year? Homo sapians developed about less than 5 millions ago, is that correct? So that appendix probably wouldn't disappear yet for many thousands of years, unless if can be use again. Maybe, with the process of change over of generations, people will be born with no appendix, does it matter? he he he!! Anyway, when we went for a long drive, one of kids raise this question that why cows always chewing everytime. Oo nga naman, kids are inquisitive and you learn from them. Cows developed this big body and they have to sustent it with enough food to survive, they need to extract those elements in the grass to become a protein to give them enough energy to for their little activity.. .. We know that there aren't much protein in grass, kaya pala laging kung naririnig... don't eat like a cow! Hindi naman ako malakas kumain huh.. pssst.. kung walang tao!!! he hehe!! They are like koala, they conserved or limit the use of their enery just for eating or moving a little, koala mainly sit down all day and eat a little.. ayyy buhay... . while cows only grass which needs extra effort to digest, they will chew a little bit, swallow it, then bring it back again in there mouth for more chewing. Isn’t it great that we developed to eat food that doesn’t take too much time to digest. We invented and created ways how can we minimized our energy for digestion. That’s why we get tired after we eat, or we can't really think too deeply after eating, it’s because we subconsciously focus our energy on digestion. This is one of our autopilot(subconsciouness) that we automatically do without thinking about it. In civilized world. we developed to eat 3 times a day and enough time given for digestion and soon we are ready to do other tasks. We dominated and have the best survival skills in this earth for many good reasons, one of those is our diet, not only we can almost eat anything, unlike some animals e.g. pandas only eat only one kind of food (bamboo). More so, human also learned and developed things that we can put our energy on other things and put less energy of digestion, such as posting here in our forum. he he he… No wonder your brain got too big than the rest of your body organs, kid!!!.. because we uses it often than the others, ummph..i haaate it when my brain hurts when I think too much..he he he.. teka mahabang discussions ito yata, he he he… maybe we can start when did human awaken their consciousness, obvious ba? eh with the use of the tools, naku, maraming imaginations iyan tools huh.... .. saka na lang iyan topic… ayyyy… would be hard for me stop talking… Pahabol pa pala… Imagine mo kung kumakain pa rin tayo ng matitigas na hilaw na flesh at damo, how long it will take us to digest it? and before it digested and use as an energy, we should start chewing soon. ummmphh wait..... on the other hand, maybe cows are better, they have a simple life… eat and eat , rest and sex a little …. hayyyyyy, what a life!!! probably, we need to open a new thread para naman sa mga animal lovers diyan.. he he he.. and their special features..???

if you believe that we started like a microscopic liquid, and something went wrong on its combinations, we can see that could resulted an abnormal parasite embryo. IF we go back to basic elements of matters... what are the composition of human? we are organic that are made of non organic, we are also made of nails or metal, this is easy to understand, if u check your multivitamins he he he.. it tells you how much iron do you need to be healthy, and iron is one kind of metal, others are lead, aluminum, tin, etc.. what makes us different from a metal. matters are combinations or either more of a concentration of any elements, put them together, they can react to each other. and with wrong combinations, and for other reasons, it is not too hard to think that these combinations could go wrong from time to time, so don't tell me this is created by all knowing and all powerful force, that would be harder to comprehend, for me at least. Why PGD is important??? maybe I got some answers in here.. Subject: Parasitic twin,etc....sometimes 2 ulo or extra legs, etc... http://www.thepinoy.com/forums/viewthread.php?tid=3368&page=#pid71628

sorry.. ang tagal ng walang follow up dito.. marami pa itong magandang topic eh.. sinisipag ako ngayon eh!! he hehe!! This is interesting again, i know its a common knowledge, but i like talking about it.. he hehe!! If we think about it, nature just repeats itself in different form, big or small, obvious or not... you see, in this stage alone they already have their own natural selection, their are 100 million sperm eggs that are being released each ejaculation, and only one sperm will fuse a female egg.. whoaaaa...tough competition. ey!! it has no difference in plant world... it has been the same concept of fertilization eversince... This is similar to pollen that male flowers releases, wind will blow these pollens in different direction, and sometimes some of those pollen can be from different area. Although, the role of bees to pollinate flowers has a tremendous result for its success, but, not all area has an insect to help some flowers to carry its pollen from male flower to pollinate a female flower. the more one flower can produce a pollen, it have more success to carry its own DNA, its similar to male's sperm count, you may heard that some men has a low sperm count, and they have problem to produce their own offspring like Tom Cruise.. he hee.. its like a shot gun effect evertime, the more you shoot, shoot, shoot.. eventually you can hit the target.. .. he he he… teka..excuse me……….. AAAAAAAAACHUUUUUUUUUUUUUUU allergy kasi ako sa pollen eh,AAAAACCHUUUUUUUUUUUUUUUUUUUUUU mataas ang pollen dito sa lugar naming, dahil semi tropical ito at very open pa naman….AAAAAAAAAACHUUUUUUUUUUU!!!! and now with the la-*test*-('") technology, there are many plants that are crossbreeds, new kind of animals has been continuing to appear in this earth from that technology.. there are many animal crossbreads are available anywhere... AAACHUUUUUUUUUUUUUUUUUUUUUUU!!!!!

on the other thread , we mentioned about regenerations... there are simple animals that are ASEXUAL, they are both female and male, so they can fertilize themselves, like seapolyp.... this special plant can pollinates itself... ummmmphhh.. THE HUMBLE THALE CRESS, Arabidopsis thaliana, pollinates itself--an ability that new research suggests it acquired relatively recently in its evolutionary history. Arabidopsis has the same genes that in cross-pollinating plants discourage self-pollination, but they have been rendered nonfunctional. Writing in the current issue of Science, researchers report that the sequence diversity in these so-called pseudogenes is rather lower than that observed in the active counterparts on cross-pollinating plants, indicating that Arabidopsis evolved self-compatibility--and the associated changes in flower shape, for example--only after 11,000 years ago or so. The image above shows Arabidopsis pollen-pistil interactions, with the pollen tubes growing toward ovules. source: science america... http://www.sciam.com

Brain and Spinal Cord
if you are following this post about vertebrates/invertebrates in next doo thread.. here's first early stage of development of embroyo's brain and spinal cord.. that 2 plates is going to connect, will the spinal cord... The embryo has a separate brain and spine. His or her brain is divided in three segments; the forebrain, midbrain, and hindbrain. http://slv80.tripod.com/TheProLifeWoman/Prenatal/outline.htm Figure 1 illustrates the general layout of the central nervous system (CNS). Of significance is that the nerves that arise from the brain and spinal cord are in pairs, i.e., one for each side of the body. http://tooldoc.wncc.nevada.edu/spinal.htm

Frog's embryo... interesting that all animal's embryos look similar in their early development Birth of a neural tube: Development of a normal frog embryo showing formation of the neural tube – the hollow structure that will become the brain and spinal cord. Blocking a gene called "shroom" disrupts closure of the tube, mimicking neural tube defects like spina bifida in humans. (Credit: Saori Haigo, John Wallingford/UC Berkeley) Single gene plays key role in neural tube defects A single gene appears to kick off a critical step in the development of the early embryo - the formation of the brain and spinal cord - and thus may offer a way to screen for fetal spinal cord defects such as spina bifida. Neural tube defects, including spina bifida - an open spinal cord - and anencephaly, or lack of a complete brain, are among the most common serious birth defects in the United States. While the incidence has gone down in this country thanks to educational efforts encouraging pregnant women to take folic acid supplements, some 30 percent of neural tube defects appear to have a genetic cause unrelated to folic acid deficiency. http://www.innovationsreport.de/print/print01.php3?id=24271&ctyp=1
