For Those Who Need Evidence of Speciation and Macroevolution
Who do you think looks more human, the above photos, or chimpanzees? Chimpanzees have complete legs, arms, fingers, rectal cavities etc., these babies do not.
In my last post people wanted evidence of macroevolution in the process, they say that no one has ever documented such an event. Well this is about as close as you are going to get without watching a species over thousands of years, and if this type of change can happen with one birth, imagine how many changes could happen with 10 billion births. I tried to explain to these people that an ape didn't just give birth to a human one day, and a fish didn't just crawl out of the water, turn into a lizard, start running while transforming from an ape and then to a naked dude. But that is the manner in which the parents and Sunday school teachers of these people taught them to make evolution seem ridiculous, and yes those examples are ridiculous. However, no one really believes that is how it happened. I kept trying to explain that genetic abnormalities or mutations happen in nature all the time, thus albinos, and downs syndrome. Some of these traits, such as baldness, eye and hair color, physique, high cholesterol etc. are passed down from one generation to the next; if your mother’s father was bald you have a good chance of being bald yourself. For some reason those inherited traits are not hard for the creationists to understand but other traits are and they contend that there is no way after a millions of years (since they don't believe the Earth has even been here that long) that something that had it's roots as one species may end up as something that looks completely different, even though it still shares over 95% of it's DNA with its ancestors.
I do realize that this isn't a good example of an actual new species that could reproduce or even survive at all. So far there is really only two cases that I know of where these babies survived past their first few hours. But let’s just say that these babies were all born with fully functional organs, which is not impossible, and that this was a trait that could be passed down from one generation to the next.
So what would happen if the babies born with sirenomelia as in the photos above, were all abandoned in one place because of this defect, isolated, and were able to reproduce, carrying on this gene that causes sirenomelia? What if they were abandoned by the sea and although they were unable to walk, they were able to swim 5 xs faster than humans and therefore were able to get to all the food sources in the sea before people with legs and therefore were able to benefit from this defect, survive and carry on as a civilization? What if one of these babies was then born with another genetic defect such as gills, or a blow hole and were able to stay underwater for longer periods of time, and therefore were able to get to the oceans food sources 10x faster than their predecessors and therefore survived as the others died and thus only passing on the their genetic mutations of no feet and gills? Wouldn't that be the macroevolution that everybody says doesn't exist? It almost seems like sirenomelia could have been the first phase of that separation of species. And if what I described above happened over a million years, and what originally came from air breathing humans, on land, with feet, became a webbed leg fish eater with gills that could survive in the sea, don't you think the DNA would be a bit different than what it started out as? And if so, wouldn't this count as a new species, even though the first time it appeared it was called a deformed human?
I am not making an argument for fish babies per say, if you do any research on sirenomelia you would come to the conclusion that the above is impossible. But what if they weren't so deformed and what if it was just a group of albinos that got isolated from the rest of civilization and instead of living in the sea or above ground, they were forced to live in caves due to sun exposure. Wouldn't the ones with better eye sight be more prosperous in such an environment, wouldn't they have a higher survival rate therefore, more likely to pass good vision on to their offspring? And over time wouldn't we eventually have a race of powder white cave dwellers with great eye sight but with extreme sun sensitivity?
These are all just hypothetical examples that draw correlations to modern human development. I know you all think I am crazier than a shit house rat but there is a point being made; you just have to find it.
