Universal Darwinism, also known as generalized Darwinism, universal selection theory, [1] or Darwinian metaphysics, [2] [3] [4] is a variety of approaches that extend the theory of Darwinism beyond its original domain of biological evolution on Earth. Universal Darwinism aims to formulate a generalized version of the mechanisms of variation ...
Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
Darwin proposes sexual selection, driven by competition between males for mates, to explain sexually dimorphic features such as lion manes, deer antlers, peacock tails, bird songs, and the bright plumage of some male birds. [129] He analysed sexual selection more fully in The Descent of Man, and Selection in Relation to Sex (1871). Natural ...
In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859).
The concept of natural selection originally developed in the absence of a valid theory of heredity; at the time of Darwin's writing, science had yet to develop modern theories of genetics. The union of traditional Darwinian evolution with subsequent discoveries in classical genetics formed the modern synthesis of the mid-20th century.
Charles Darwin's 1859 On the Origin of Species is usually considered to be the starting point of contemporary understandings of evolution. [1] The history of evolutionary thought extends from antiquity to contemporary developments including the modern evolutionary synthesis , the extended evolutionary synthesis , and universal Darwinism .
The cosmic web (sometimes called the cosmic net) began as material connected to the first galaxies in the known Universe. As clumping began, their gravitational influence became more pronounced ...
Darwin himself openly deplored the author's "poverty of intellect", and dismissed it as a "literary curiosity". However, the high profile of the public debate over Vestiges, with its depiction of evolution as a progressive process, and its popular success, would greatly influence the perception of Darwin's theory a decade later.
