Higher forms of life, birds, reptiles, mammals, all tend to reproduce sexually rather than asexually. I'm sure there may be exceptions, my biology knowledge base isn't wide enough to point them out, but asexual reproduction tends to happen in lifeforms like bacteria and worms. I'm not asserting that early humans reproduced asexually. They reproduced sexually, and did so with other species.(February 12, 2013 at 9:49 pm)festive1 Wrote: How can you neglect the fact that these people would have been inbreeding with close, biological relatives for multiple generations? It didn't work for the European aristocracies, many developed genetic diseases such as hemophilia, it certainly would have been less successful 6,000 years ago when Christians believe all of this was going on.1. I'm not neglecting it. My position is that A&E's genome had lots of variation built in to it and had far fewer defects than today, so inbreeding was at first not a problem. By the time we get to the patriarchs, we see Abraham married to a half sister. 400 years later in the law, that is not allowed. Errors are accumulating in the genome.
2. What's your answer to the problem? In the evolutionary paradigm life begain as asexual. There was necessarily some starting point to sexual reproduction. What's science's answer to the alleged inbreeding problem, and what is its evidence for that answer?
Quote:However, an analysis of a first draft of the Neanderthal genome by the same team released in May 2010 indicates interbreeding may have occurred.[13][14] "Those of us who live outside Africa carry a little Neanderthal DNA in us," said Pääbo, who led the study. "The proportion of Neanderthal-inherited genetic material is about 1 to 4 percent. It is a small but very real proportion of ancestry in non-Africans today," says Dr. David Reich of Harvard Medical School, who worked on the study. This research compared the genome of the Neanderthals to five modern humans from China, France, sub-Saharan Africa, and Papua New Guinea. The finding is that about 1 to 4 percent of the genes of the non-Africans came from Neanderthals, compared to the baseline defined by the two Africans.[13]Bolding mine. http://en.wikipedia.org/wiki/Neanderthal
This indicates a gene flow from Neanderthals to modern humans, i.e., interbreeding between the two populations
Where's your evidence that Adam and Eve had perfect DNA, incorruptible from inbreeding? It seems to me that the evidence supports a cross breeding of at least neanderthals and humans, if not other sub-species of humanoids rather than, "In the beginning there were two perfect people who populated the world."
