..." there is data demonstrating that humanity descended from two humans."....

That's news! Just what is the data for that?

 I did that National Geographic G-nome test. according to that, they traced my g-nomes back to a single male ancestor living in Africa some 2 million years ago. Not sure if that ancestor was 'homo sapiens' yet, or not.

Same way, seems they can trace any female alive today back to a single ancestor.

Pretty close, but nothing to demonstrate whether than ancestor for females ever lived at the same time or the same savannah as the ancestor for today's males. No proof they were a 'couple'.
