Darwin
Charles Darwin was born on february 12 1809 (same as Lincoln) and he transformed science !!
The theory of evolution !
2 reasons why why biologists took so long to accept it: humans were reduced to animals (we share the same genes) and for a species to perpetuate, it is the female who chooses the best mate to insure the best descendance, not the male.
This also means, a very long time ago, on Earth, a living unicellular organism was produced and evolved into the enormous diversity of life we know today....That first life form was our real Creator. Not the other one.
