Homo Sapiens Sapiens, who seem to have evolved in the northwest corner of Africa, now exist in every climate on Earth. We don’t actually know what we’re capable of.

Homo Sapiens Sapiens looks to be something like 300,000 years old. That’s very young as species go. Before (and a while after) that, there had been other Homo species for about 4,000,000 years.

H. Sapiens spread across the earth in a couple tens of thousands of years. But aside from little variations, there’s not a ton of evolution happening. We’re all H. Sapiens Sapiens.
