If you check medical records just over the past century, you will
find that humanity has evolved somewhat, probably because of improved

The average person is several inches taller now than two centuies ago.
I stand almost 8 inches taller than my parents did.

and allow them to reproduce. The basis of evolution is, after all,
survival of the fittest.
