I was pondering why Dinosaurs were so large millions of years ago, and
thought about the strength that their bones would have needed just to
support the muscular structure of the animals. I propose that the
gravitational force on earth has become greater over time, causing living
beings to become smaller. Does anyone have a comment on this?
