Descriptive evolutionary ethics consists of biological approaches to morality based on the alleged role of evolution in shaping human psychology and behavior. Such approaches may be based in scientific fields such as evolutionary psychology , sociobiology , or ethology , and seek to explain certain human moral behaviors, capacities, and ...
Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution ...
Evidence for the evolution of Homo sapiens from a common ancestor with chimpanzees is found in the number of chromosomes in humans as compared to all other members of Hominidae. All hominidae have 24 pairs of chromosomes, except humans, who have only 23 pairs. Human chromosome 2 is a result of an end-to-end fusion of two ancestral chromosomes ...
Because of the perceived value of evolution in applications, there have been some expressions of support for evolution on the part of corporations. In Kansas , there has been some widespread concern in the corporate and academic communities that a move to weaken the teaching of evolution in schools will hurt the state's ability to recruit the ...
It is likely that early ancestors of humans lived in groups of similar size. Based on the size of extant hunter gatherer societies, recent paleolithic hominids lived in bands of a few hundred individuals. As community size increased over the course of human evolution, greater enforcement to achieve group cohesion would have been required.
The term "human rights" has replaced the term "natural rights" in popularity, because the rights are less and less frequently seen as requiring natural law for their existence. [10] For some, the debate on human rights remains thus a debate around the correct interpretation of natural law, and human rights themselves a positive, but ...
In Boyd and Richerson's view, cultural evolution, operating on socially learned information, exists on a separate but co-evolutionary track from genetic evolution, and while the two are related, cultural evolution is more dynamic, rapid, and influential on human society than genetic evolution.
