Human Growth and Development / Unit 1 HGD 0037 short lesson, about 20 seconds
Evolution and Behavioural Genetics
Captions available
The idea
Evolutionary psychology studies how universal human patterns evolved; behavioural genetics studies how individual differences arise now through genes and environment.
In practice
Why humans in general form attachments, against why one sibling is shyer than another.
Where people slip
Evolutionary psychology looks for traits that aided survival and reproduction, such as attachment and prosocial behaviour. Behavioural genetics relies on twin and adoption studies.
