From this article. See it for details.
"Evolution is an ongoing process, although many don’t realize people are still evolving. It’s true that Homo sapiens look very different than Australopithecus afarensis,
an early hominin that lived around 2.9 million years ago. But it is
also true that we are very different compared to members of our same
species, Homo sapiens, who lived 10,000 years ago — and we will very likely be different from the humans of the future.
"What
we eat, how we use our bodies, and who we choose to have kids with are
just some of the many factors that can cause the human body to change.
Genetic mutations lead to new traits — and with the world population now
above 7 billion and rising, the chances of genetic mutations that
natural selection can potentially act on is only increasing. Don't believe us? Inverse presents three examples of recent changes to the human body."
