Charles Darwin is best known for his study on evolution and his book titled "The Origin of Species". Much of Darwin's work was written when he saled around the world in the HMS Beagle and his time spent on Galapagos Island. While doing so, he realized that there were many of the same plants and animals, but they all had slight variations. The slight variations allowed the species to adapt to its environment. However, he argues that the adaption didn't occur to allow the species to live there, but the variations occured first, and then they were allowed to live there better than the other species, which in turn allowed them to overtake and outlive the other variations. Read some quotes from Charles Darwin below.
A man who dares to waste one hour of time has not discovered the value of life.

At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate, and replace the savage races throughout the world.
Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
