Full Answer
Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual.
Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.
In his book The Geographical Distribution of Animals, he divided the world into six regions. Wallace's experiences led him to discover the theory of evolution by natural selection - independently from Darwin.
Scientific career Wallace was one of the leading evolutionary thinkers of the 19th century and made many other contributions to the development of evolutionary theory besides being co-discoverer of natural selection.
The four key points of Darwin's Theory of Evolution are: individuals of a species are not identical; traits are passed from generation to generation; more offspring are born than can survive; and only the survivors of the competition for resources will reproduce.
Charles Darwin and Evolution Darwin's Theory of Evolution by Natural Selection ties together all of the life sciences and explains where living things came from and how they adapt. In life, there is heredity, selection, and variation.
One day in 1858, while feverish and confined to his hut on the island of Ternate (now in Indonesia), Wallace had a realisation. He came to understand how species evolved - they changed because the fittest individuals survived and reproduced, passing their advantageous characteristics on to their offspring.
Charles Darwin is commonly cited as the person who “discovered” evolution. But, the historical record shows that roughly seventy different individuals published work on the topic of evolution between 1748 and 1859, the year that Darwin published On the Origin of Species.
Darwin and Wallace used DNA evidence to support their ideas about evolution and how species are related.
Wallace devised the first modern definition of what a species is - a slightly modified version of which would later become known as the Biological Species Concept; in addition he believed that speciation typically occurs in allopatry or parapatry - when diverging populations are geographically separated or abutting.
