But still having physical strength can add as an extra benefit

Then why is it that the intelligent species are not the physically strongest ones?

Can we reason the fact that during the start of life on earth there was first the development of physical traits but then it started to get diminished and the mental traits grew... i.e. organisms evolved to become more intelligent rather than growing in size?
