At Least By 100,000 Years Ago, Humans Looked Just Like Us

(p. 22) The exact time . . . protohumans became fully modern humans is of course debated. Some say 200,000 years ago, but the undisputed latest date is 100,000 years ago. By 100,000 years ago, humans had crossed the threshold where they were outwardly indistinguishable from us. We would not notice anything amiss if one of them were to stroll alongside us on the beach. However, their tools and most of their behavior were indistinguishable from those of their relatives the Neanderthals in Europe and Erectus in Asia.
