quote: Eve is just a lot older, ie from before Neanderthals and modern humans split.
quote: Given the hard definition that a species is different if it can not produce viable offspring the neanderthals and modern humans are not the same species, but maybe subspecies.
quote: It would be a lot easier for creationists to claim that $deity 'formed' Earth over billions of years (intelligent design theory perhaps?) rather than poofed it into existence.
quote: However the only people who think there is still a debate about how old Earth is are Creationists.
quote: This article is saying white people have more Neanderthal genes than Africans and Asians? Cause I actually believe that.
quote: What the hell does this have to do with high tech?
quote: Roughly 500,000 year ago, the breeding populations that would evolve into humans (Homo sapiens) and Neanderthals (Homo neanderthalensis) separated. ...But the long estranged relatives would come into contact ...roughly 80,000 years ago.
quote: These population sizes are effective sizes and so are likely to be an order of magnitude lower than the census size, which implies that for populations to be sustainable over more than a few hundred generations they must number in the thousands or tens of thousands.
quote: In this case we are looking at 20,000 generations, so we'd have had to start the time frame with a population greater than 10,000, meaning our current world population should be ... Population growth formula: N= N0*exp(kt) where N0 is the population at the start of a time frame (in this case it would have to be a minimum of 10,000 for us to survive 500,000 years), k=population growth rate (1.36% per year), and t= time frame (50,000 ... yes, but 500,000 won't work in my spreadsheet, so I'm using 50,000). The answer is our world wide population would be 2 E 299 (2 x 10^299) meaning our population would exceed the entire square metres on the planet's surface.
quote: All in all, the plague reduced the world population from an estimated 450 million down to 350–375 million in the 14th century.
quote: To hunt down Neanderthal genes, the researchers first sequenced 846 people of non-African heritage (who likely contained Neanderthal genes) and 176 people from sub-Saharan Africa (who likely did not receive Neanderthal genetics). These sequences were then used to pinpoint the genes that the non-African humans (e.g. Europeans) shared with Neanderthals, but which weren't found in people of sub-Saharan African origin.
