Data from half a million people show that natural selection has not stopped
It does, however, no longer seem to favour braininess

This study is done on white British men and women over age of 45-50, so no immigrants.
Many traits vary among different members of a population of humans and animals, from body size to hair colour, and those differences are often linked to differences in genes. Natural selection occurs when some of those traits help some individuals survive and reproduce more than others. That causes their genes to become more common in the population over time, and it's the way species evolve to adapt to changes in their environment. To see what traits were being selected for in humans, the researchers used DNA and medical data from more than 200,000 women over the age of 45 and 150,000 men over the age of 50 — that is, people who had mostly finished having babies — from a huge database of volunteers in the U.K. called the U.K. Biobank.
