History
William Donald Hamilton was a British evolutionary biologist. Hamilton became known for his theoretical work expounding a rigorous genetic basis for the existence of altruism, an insight that was a key part of the development of the gene-centred view of evolution. He is considered one of the forerunners of sociobiology. Hamilton published important work on sex rations and the evolution of sex. From 1984 to his death in 2000, he was a Royal Society Research Professor at Oxford University
