Well, yeah, in the sense that a chimp and a human are about 98.5% similar.

But from that point of view, humans are 99.9999% similar.

The other point-of-view is that a male and a female of a species will end up with approximately 50/50 similarity to either parent.

These are different measures coming from different point-of-views. If I were Gengis Khan (and who is to say that I was not!), then I could have impregnated enough women over my days on the steppes, to have, 1000 years late, up to countable percentages of my far-far-far descendents actually detected in tests as being my actual descendents.

Please don't conflate "this dna comparative measure" with "that dna comparative measure". It's all (theoretically) straight forward, and, yes, compounded by empiricism, but these are different measures, regardless.
