Different species of humans?

There is, we call them 'Westboro Baptists'.

 

No, we are the only species of human left. This isn't a matter of opinion it's fact (supported by evidence).

 

:lol:

 

Definitely,there has to be some species to evovle to something new.

 

Oh. I read the second question wrong. Never mind.

What, do you think there are neanderthals (sp?) hidden in some undiscovered place?

 

No, I don't think so. I'm under the impression that evolution of a species into a new species is a long process and fuelled by natural selection. Considering how most humans survive, rather than the fittest, and we don't have to struggle for life, we don't evolve that much.

 

We're the only remaining members of Genus Homo. Unfortunayely, the reason they're dead is probably that we killed them off.

 

You, sir, deserve an award for that comment.

Have a dancing banana: (!)

 

A different homo species on Flores could have existed up until ~12,000 years ago, around the same time as 'cities' of 500+ people started to develop around present day Iraq/Syria.

 

We are currently one species of humans, although there might be traces of interbreeding with other similar species from the past.

 

Why, thank you *bows* :lol:

 

Same species, different phenotypes. To have different species you have to have, among other things, an inability for a member of one group to mate with a member of the other group who is of the opposite gender. Think dogs.

 

Specifically, members of different species cannot reproduce to produce fertile offspring. As far as I know, there are some mixes (think horse and donkey) that can reproduce, but their offspring aren't fertile.

I'm sure if you go far enough back, we'll find a group of humans we couldn't have reproduced with, but if you're referring to neanderthals, europeans have 1-4% neanderthal DNA, meaning we did reproduce with them. And no, there certainly aren't separate species of human wandering around unnoticed. We have a VERY large population base, and we've explored virtually every part of the land on this planet. I find it highly improbably that we have yet to come across a civilisation build by another species.

 

No, no one is exactly the same. But it has already been established that it is not a different species if reproduction to produce fertile offspring is possible, and its safe to assume that people of opposite gender, assuming there is no infertility or damage to the reproductive system, should be able to reproduce.

All humans are supposed to share a common ancestor who was a human with the same phenotype, as in a homo sapiens, and there hasn't really been time to evolve into another species yet.

 

Neanderthal - Wikipedia, the free encyclopedia

are they not different enough?

 

We reproduced with them though. And apart from what remains of them in our DNA, they are extinct.

Oh, and PS, we killed them, us humans. As in genocide.

 

so they DID existed. just in the past
