Evolution has benefited manking in more than one way. Firstly evolution allowed for biology to become a science, and thus through biology medicine benefited. Our understanding of the organisms be they worms or birds or human has taken the art of healing from excorcisms to where it belongs: In hopitals. Let us not forget that Biology without the ttheory of evolution makes no sense. Also All science is interrelated; biology,geology,chemistry etc, all have a common denominator: The laws of physics. Anyone who thinks evolution has not benefited mankind is ungrateful to say the least. He or she enjoy the fruits of science but on the other hand they denounce it.
Mighty is the sword that draws blood!
Mightier is the Pen that draws ink!
Mightiest is the tongue that draws ears! (Yiannis Mantheakis)
