Hmm. Human and Neanderthal, at least from the genetics data? But, yeah, 
it would be hard to pin down unless you had a case like that, where 
there where clear markers that couldn't arise otherwise, in some 
sub-group of the survivor, while the main group those markers came from 
went extinct. In most cases, the result would homogenize the gene pool, 
erasing, over time, any evidence.
