The main difference between this creature and contemporary apes was that our grandpop had smaller teeth and an arched foot. Male chimpanzees vie for the attention of females by fighting each other, biting with their strong teeth. But a guy with a sexy high instep – he can walk upright instead of on his knuckles. This frees his hands to carry back food for his mate. Grandmama was no fool, and here we are today.
And that’s why good posture is regarded as beautiful in figure skating.
