Human evolution: How will our species change over next 100,000 years?

| | September 27, 2016

Since we became Homo sapiens, has evolution changed us in any way? Actually, yes.

[An] example is the gene for lactose tolerance. Primitive man would drink milk as a baby, then never again, so the amount of lactase enzyme (which breaks down a common sugar in milk) would fall after a few years of age. Over time, however, humans have evolved so that certain populations will keep producing the enzyme into late adulthood….

Our mouths are changing too. They are getting smaller and more bullet shaped. Our teeth aren’t quite changing as fast, which is why orthodontists and wisdom teeth removal still exists…, for now. More and more people are being born without wisdom teeth, or have their wisdom teeth erupted later if at all.

So how will we look like 100,000 years from now, assuming we still exist that far in the future? Even if we ignore new technologies, moving off the earth, and various selection pressures, evolution still has surprises just by chance mutation.
