Scientists used data from the UK biobank. They also got access to the genetic material of the remains of long-dead Europeans. Ancient and modern people were compared with each other.
Scientists have found evolutionary changes in 755 genes associated with various traits, such as skin pigmentation.
In particular, the researchers learned that the early settlers in Europe had darker skin. Over time, people have become lighter-skinned. The researchers also found changes related to vitamin D intake, heat regulation, and body size. These things could also be related to climate change.
