Neanderthals, humans didn't mix

National Geographic "morphed" a couple of pictures of an adult and a child, to match Neanderthal bone structure. The resultant images weren't all that strange looking.

I think that people have to keep in mind that Neanderthals and Homo Sapiens shared the same range for tens of thousands of years, too. So it's not like they were trying to wipe eachother out in wars.

The appear to have co-existed for tens of thousands of years! We can't even co-exist amongst our own species for a few months. I find that an amazing concept.
 
Denise,

It is not hard to find conflicting views on the wolf/dog species/subspecies thing. Recently, dogs were reclassified as Canis lupus familiarus, recognizing their almost complete genetic identity to wolves.

Since they breed true (fertile hybrids), and since this is the common definition of species, most taxonomists today would classify them as the same species.

But of course the term "species" is itself the subject of much debate, and the term "subspecies" is not even considered meaningful by some.
 
This "fertile crosbreeding" speciation criteria is mainly theoretical. I mean, there's a couple of million species out there, how many do you think we have tried to cross-breed? ;)

Denise, what about Tions?

Yes, that's pretty much the point I was trying to make.

Ornithologist Ernst Mayer illustrated this by likening species to watching an individual Paramecium in the process of division; at the beginning of this process, it is easy to say, "here is a single paramecium"; and at its end to say, "here are two"; but at any middle point in the process, the question is not so easy to answer.

Don't you think it's fascinating to think what life would be like with a competing species? Us humans have been at the top of the food chain for so long. Would the Neanderthals have their own nations? Imagine the UN!

Professor Marvel- the original Ozzy!

This is tangential to this topic, but that never stops me:

A hot theological topic of the Middle Ages was whether or not sexual acts with demons would produce offspring. Apparently, this sort of thing happened all the time...
 
We must have posted at the same time. Above is adult picture. No humps. Don't know if it is humping or has been humped either.:D
