Answer 1

Fun fact: *H. s. sapiens* (Dass us we subspecies) is probably the least genetically diverse animal that isn’t on an endangered list. We’re also in possession of a few extreme morphological quirks recently acquired in our evolution (including windpipes prone to blockage by our larynxes, receded snouts, structurally unsound spines and leg joints, a damn near suicidal birthing paradigm, exploding appendices, and the most overly complex and self-defeating behavioral programming in literally all of nature)

So to answer your question: Didn’t.
