Apr. 25, 2013 — In many places around the world, people are living longer and are having fewer children. But that’s not all. A study of people living in rural Gambia, published in the Cell Press journal Current Biology on April 25, shows that this modern-day “demographic transition” may lead women to be taller and slimmer, too.
“This is a reminder that declines in mortality rates do not necessarily mean that evolution stops, but that it changes,” says Ian Rickard of Durham University in the United Kingdom.
