Human evolution may no longer be driven primarily by genetics, according to a new theory by researchers at the University of Maine which claims that cultural systems are now shaping the way humans ...

We often hear that mental health problems are “in the genes.” It’s a familiar story: anxiety runs in families, depression is a chemical imbalance, and maybe you inherited a predisposition to feel the ...
