Why do we, alone among primates, retain rounded breasts when not nursing?
And why do we, compared to our human ancestors, have cute child-like skulls and slender graceful bones?
Why do we love singers and singing, and dancers and dancing, and painting pictures on cave walls?
Here’s a hint:
We value gold not for what it can buy us, but because its lovely luster doesn’t tarnish,
and it is so readily malleable that it can be easily worked into beautiful jewelry that we can
wear when we go out.
