Re: Bill Nye: “Creationism is not Appropriate for Children”
People are already a lot bigger than they were 1000 years ago.
While strength and size has probably been selected for, the main cause of this has probably been due to nutrition allowing the already existing anatomical genes to present at a fuller potential. Look what happened to height in many immigrant populations once introduced to the western diet.
Mind: there are benefits to smaller stature such as less nutritional need to fuel it. (Particulary in large) populations with questionable stability in their food sources would naturally select for those who can survive food shortages the best.
