Humans are still evolving
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.”
The figure I usually see for the timing of the brain we have today is 200,000 years ago. Differences in perspective, intellectual interests, and resulting behaviors are often attributed to social and environmental contexts rather than to genes (but allowing for epigenetic effects) or essential brain structures and capacities. Not saying I don’t believe in cases of quicker evolutionary changes but these, to my knowledge, have not fundamentally changed the human brain for 200 millennia.
This wiki also notes some relatively recent genetic variation. The referenced sources include a number of scientific journals.
