Inter-Species Sex.

<p>Sounds like time for a new Star Trek series.</p>

<p>I don’t think our current views on inter-species sex (other than the Star Trek kind) can be generalized to prehistoric times.</p>

<p>There are no species anywhere near as closely related to us as these various hominid species were related to each other. Mating with a member of another species might not have seemed particularly freaky – especially to people who had never heard of the concept “species.”</p>

<p>I can easily imagine a prehistoric traveler or two visiting a community of people different from themselves, learning their culture, becoming accepted into the community, mating a local person, and having children. Would it really have mattered all that much if the community they joined was a culturally different community within their own species or a community of people of a very closely related species?</p>

<p>I don’t know what it may mean, but I am fascinated with DNA sequencing and what it can teach us about current populations.

<p>I imagine that there were probably bands of various closely related species coexisting, sometimes peacefully, other times less peacefully.</p>

<p>I also imagine that there were prehistoric interspecies wars, possibly including a war to end all wars where humans vanquished all other related species.</p>

<p>I imagine an alien species visiting earth 50,000 years ago, having sex with a few humans, then leaving, never to be seen on Earth again.</p>

<p>Note the objections, as highlighted in the Times article. I’m skeptical but willing to be convinced. Remember, these are statistical analyses of material whose reliability is questionable. Consider, for example, the recent stories about the DNA of James Watson, the DNA nobel winner; his DNA shows he should be deaf and blind so somewhere there is an error, either in the material, in the way it was recorded or in our understanding of what it means.</p>

<p>Title of thread made me click…</p>

<p>I could imagins space aliens coming down and releasing humans out of volcanoes.
Wait, that has already been said!</p>

<p>The study of genetics can lead to some VERY strange things!</p>

<p>And never mind the fact that we are all descendants of primitive worms and their like. </p>

<p>For some reason I always think about this when fishing.</p>

<p>We were just watching a show on Animal Planet - River Monsters!
“Hunting Pacu in Africa” , but when we got home we read that they are now in Illinois.</p>

<p>Apparently created by lesbian atheists. :rolleyes:
Not sure if this site is for real :confused:</p>

<p>The fish are though. :eek:</p>

<p>Toblin, your link really freaked IE out, making it open a ton of windows.</p>

<p>What i was going to say was that it is certainly possible for this to have happened. It could account to some of the odd features found in some sites.</p>

<p>Re: Polar Bears once mated with Grizzlies…</p>

<p>Never thought about that before, but is that something that couldn’t physically happen today…even in a lab? Would there be no fertilization?</p>

<p>^it can still happen, and has happened. Granted the offspring may not be able to reproduce, but it is still possible.</p>

<p>Kinda like how horses and donkeys can mate. Along those lines.</p>

<p>

</p>

<p>If it’s on the internet it’s true. And I’ve heard they’ve been found in the lakes and streams in and around the more conservative towns in New Jersey.</p>

<p>Something to think about.</p>

<p>In one of Jane Goodall’s books, she talks about how she observed an adolescent chimpanzee and an adolescent baboon have sex. Just two hormone-crazed adolescents trying to relieve some pent up sexual frustration, since they weren’t really old enough to be considered “seriously” contenders for mating in their actual species family groups. Female chimp and male baboon, IIRC.</p>

<p>Netflix streaming: TedTalks, Ancient Clues, Episode two, Svante Paabo talks about DNA clues to our Inner Neanderthal. Watched it last night. V. interesting. </p>

<p>Also there is the concept of an ecocline: there is variation in nature. The variation exists in populations. As you move geographically across a species’ range there will be subspecies forming from that variation - certain types do better in different parts of the range. If something happens to isolate a population from interbreeding with the rest of the population, speciation can occur. <a href=“http://en.wikipedia.org/wiki/Cline_(biology[/url])”>http://en.wikipedia.org/wiki/Cline_(biology)&lt;/a&gt; Then if something happens to get the populations together again interbreeding can occur.</p>

<p>Some families have a name for the strange subspecies located out on the distant lower branches of their family trees: inlaws.</p>

<p>Isn’t the polar bear Ursus horribilus arctus? A subspecies of grizzly bear?</p>
