Linear Pottery culture
Their diet probably didn't contain enough energy for them, as they often did not grow as tall as the people who came before them, or as people do now. This might have also been because of disease, which can spread more easily in a village than it can when people are moving about a lot and not seeing many other people, as people did before the Neolithic. People in the LBK culture probably died quite young, in their twenties or thirties, and many of their children would die before they grew up.
