A common leadership philosophy in business is to get better before you get bigger. With evolution it doesn’t work that way. Evolution doesn’t plan ahead. If it would, the human body would certainly not be getting taller in a world of dwindling resources. Evolution is purely a trial and error process, but it does allow to take knowledge from the past into the future. Quite possibly beings learn something in times of physical growth that is beneficial for times of shrinkage. Sometimes things need to become bigger before they get better, which in our vision primarily means smaller but at least just as good.
Present tall human size may in fact create the embodied knowledge for a future smaller sized human species. For dinosaurs to evolve into birds they first grew big, and then shrunk. Sometimes BIG initiates developments unimaginable if things had remained SMALL. An increase in size leads to a different set of challenges and solutions. But SMALL can still benefit. Birds might not have come into existence if it were not for the increased strength and greater lightness in bone structures of tall dinosaurs, eventually enabling birds to fly. Man is at its tallest size ever, and some believe we can’t or at least shouldn’t get taller than this. But before we shrink to a more practical size, what have we learned from being this tall? Stronger bone structure? A more efficient metabolism? Another embodied perspective on time and space? An understanding of the interconnectedness of all life?
