Human haplogroups

I am not a professional in this field so please bear with my ignorance. I try to be science literate where ever I can.

 

My question is: Do genetics broadly and haplogroups more specifically rule out humans descending from more than one gene pool of common ancestors?

 

To put it another way: Could it be possible that there was more than one beginning of Homo Sapiens than a single population in Africa 200-300K years ago?

 

Thanks.

Let me be more specific to see if I can elicit some responses. This is primarily a population genetics question, I think.

If we had not sequenced the nuclear genome of Neanderthals, could we have come to the conclusion that some of their DNA is in non-African haplogroups? If the answer to that question is yes, then how?
