The evolution of humankind
An opposing digit, the use of tools
Inventing the wheel, exploring space
Brain size still developing
Two men and a referee
Foam gloves and a silver cup
Devolution about to begin
Round one, ding, ding!
A perfect right to the other`s chin
No tools, wheels, or exploration
Brain size still developing
The evolution of humankind
The evolution of humankind
The evolution of humankind
The evolution of humankind
