Guest Posted May 21, 2011 Posted May 21, 2011 I think there is still some debate about whether Neanderthal co-mingled. There are some questions of the interpretation of the DNA analysis but if they did contribute, it was only in certain combinations that allowed fertile offspring. There are some questions about the dating of Neanderthal remains also that put the hybrid hypothesis in question. Here are some links: http://www.physorg.com/news/2011-05-neanderthals-died-earlier-believed.html Here is the article with a synopsis on genetic compatibility http://blogs.discovermagazine.com/gnxp/2011/04/neandertal-hybridization-haldanes-rule/ Here is an excerpt from the original paper that I downloaded. I will link where I accessed the download but if it doesn't work you can google it: http://www.hypothesisjournal.com/index.php/main/article/download/215/pdf_1 A third scenario, which is consistent with our knowledge of interspecific hybridity, is that female Neanderthals were incapable of producing fertile offspring with male humans. The suggestion that Neanderthals practiced patrilocal mating behavior (30) becomes more nuanced in the light of data indicating that the contribution of nuclear DNA from Neanderthals to humans came uniquely from male Neanderthals. The idea that Neanderthals and humans were able to interbreed is not new (31), but the most recent data, coupled with an understanding of interspecific hybridity, allows us to conjecture that only male Neanderthals were able to mate with female humans. If Haldane’s Law applies to the progeny of Neanderthals and humans then female hybrids would have been much commoner than male hybrids. Interbreeding between male Neanderthals and female humans accounts for the presence of Neanderthal nuclear DNA, the scarcity of Neanderthal Y-linked genes, and the lack of Neanderthal mtDNA in modern human populations. Thus, gene flow from Neanderthals to humans was the product of male Neanderthals mating with female humans to produce fertile female hybrids.
Guest WesT Posted May 22, 2011 Posted May 22, 2011 Thanks for the links Jodie. Very interesting. Yeah it makes more sense there would be a hybrid from a male Neaderthal and female human. Being a man I know how we operate, we like a visual.. So from that perspecive, I can see why Human males didn't interbreed with Neanderthal women. We didn't find them attractive. Gibbons are apes that produce hybrids in nature and in captivity and are in a state of evolving very quickly. My point here being, primate species that have a relatively recent common ancestor are able to hybridize with greater success. There's an intersting video I watched at the bottom of the page from the second link. The reason I found it interesting is because I'm friends with someone who had a close encounter with something in the foothills of the Jefferson National Forest here in Virginia. And he got a real good look at it in broad daylight. When he went to the library, to see if he could identify what he encountered, the closest thing he could find in the books there (of what it looked like) was a pic of a Neanderthal.
Guest Po Commander Posted May 23, 2011 Posted May 23, 2011 I chose 'other'. A Bigfoot is a human in a costume, or a misidentified bear/large mammal. Until there is any proof whatsoever, I'm going to have to assume the worst of it's existence.
Guest vilnoori Posted May 23, 2011 Posted May 23, 2011 Looking at the above image, I think that our North American sasquatches are probably that middle arm of very large, robust, tool-poor Homo erectus, reaching up to present day instead of extinct like the graph portrays, that Almas might be Neanderthals, and it is also possible that the little people seen in Southeast Asia could be populations related Homo floresiensis. I still haven't seen or understood what distinguishes H. floresiensis from Homo habilis, both were very small people, though of course habilines were African and very early, merging in the early days out of Australopithecines. We really have no idea how well each of these species (if they were separate species) could interbreed or even if the VERY small sample of fossils we have are representative of a single species with a lot of variability (especially given the big gaps of time between them).
Guest DWA Posted June 17, 2017 Posted June 17, 2017 We may not classify this an ape, at least not on the same branch of the primate family tree as existing ones (even though mountain gorilla shows up a surprising amount in discussions of potential affinities). My candidates among known possibilities: 1. Robust australopithecines 2. Dryopithecines 3. Gigantopithecus That's in rough order; dryopithecines have turned up across a surprisingly broad range. The absence of robust australopithecines from fossil records anywhere other than Africa is just fossils doing what fossils do. (Us doing what we do, rarely finding them.) It has no bearing on what sasquatch might be; morphological resemblances and how those might have evolved in radiation to the temperate zone fuel my opinion. Really, I might not even put Giganto on here, except two seemed kinda thin. :-D That's a simple case of right - sort of - fossil, right place, but what is speculated about Giganto doesn't make me too supportive. I'm placing a significant side bet that we have not found fossils for any sasquatch ancestor yet, particularly since the NA primate record leaves open, through simple parsimony, the possibility that sasquatch might have evolved here.
