Social theories based on biology gained renewed support after 1953, when American biologist James Watson and British biologist Francis Crick successfully described the structure of the DNA molecule, the building block of all life. Born in Ealing, Middlesex, on May 4, 1825, and educated at Charing Cross Hospital, London, Huxley received his medical degree from the University of London in 1845 and was admitted to the Royal College of Surgeons.

During the 1960s anthropologists interested in the influence of DNA on human behavior produced studies of the biological basis of aggression, territoriality, mate selection, and other behavior common to people and animals. His observations on the medusa family of jellyfish led to the formulation of the zoological class Hydrozoa and to the realization that the two germ layers found in members of this class are comparable to the two germ layers that arise in the early embryological stages of higher animals.

Part of the attraction of Darwin's work for Haeckel lay in its philosophical implications.

He attempted to use evolution to construct a unifying theory of biology, science in general, and even religion.

Continuing the breeding experiments, he found that the self-pollinated AA bred true to produce pure tall plants, that the aa plant produced pure dwarf plants, and the Aa, or hybrid, tall plants produced the same three-to-one ratio of offspring.

In 1978, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) declared the islands a World Heritage Site, saying they are of such outstanding interest that they should be preserved as a heritage of all mankind.In the United States, Spencer gained considerable support among intellectuals and some businessmen, including steel manufacturer Andrew Carnegie, who served as Spencers host during his visit to the United States in 1883.Critics of social Darwinism seized on these comments to argue that Sumner advocated a dog-eat-dog philosophy of human behavior that justified oppressive social policies.Some later historians have argued that Sumners critics took his statements out of context and misrepresented his views.is applied loosely to anyone who interprets human society primarily in terms of biology, struggle, competition or natural law, a philosophy based on what is considered the permanent characteristics of human nature.
