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.
Charles Darwin's grandfather Erasmus Darwin outlined a hypothesis of transmutation of species in the 1790s, and French naturalist Jean-Baptiste Lamarck published a more developed theory in 1809. Both envisaged that spontaneous generation produced simple forms of life that progressively developed greater complexity, adapting to the environment ...
Charles Robert Darwin (/ ˈ d ɑːr w ɪ n / [5] DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, [6] widely known for his contributions to evolutionary biology.
Darwin's first sketch of an evolutionary tree from his First Notebook on Transmutation of Species (1837). Charles Darwin became a naturalist at a point in the history of evolutionary thought when theories of Transmutation were being developed to explain discrepancies in the established faith based explanations of species.
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.
Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution. A ...
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). Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
