The Autobiography of Charles Darwin by Charles Darwin
Darwin Darwin TOC Template: Darwin header Special: Embryology History History: Charles Darwin — where he was right and wrong. Tim Harding. Charles Darwin — where he was right and wrong by Tim Harding, B. The essay is based on a talk presented to the Mordi Skeptics on Tuesday 5 May Charles Darwin is best known for his major contributions to evolutionary theory.
In , Darwin published his theory of natural selection as the mechanism of evolution in his revolutionary book On the Origin of Species.
This book provided compelling evidence overcoming the scientific rejection of earlier concepts of transmutation of species. The basic principles of his theory have been shown to be correct and are now widely accepted as the basis of mainstream zoology, botany and ecology. On the other hand, in a later book Darwin got it wrong with the mechanisms of inheritance. Darwin knew that there must have been a physical mechanism for inheritance, but his speculations about it — called pangenesis — were incorrect.
Fortunately for the credibility of his theory of evolution by natural selection, he published these speculations later in a separate book titled Variation of Animals and Plants Under Domestication.

Darwin went to Edinburgh University in to study medicine. Grant revealed his enthusiasm for the concept of transmutation of species the altering of one species into another , but Darwin initially rejected this concept probably for religious reasons. Ideas about the transmutation of species were controversial as they conflicted with theological beliefs that species were unchanging parts of a designed hierarchy and that humans were unique, unrelated to other animals.
In December , Darwin had joined the Beagle ship voyage as a gentleman naturalist and geologist. As the Beagle neared England in , he began to think that species might not be immutable after all.
Unconventionally, Darwin asked questions of fancy pigeon and animal breeders as well as established scientists. Darwin related this to the struggle for existence among wildlife and plants, so that the survivors would pass on their form and abilities, and unfavourable variations would be destroyed.

By December , he had noted a similarity between the act of breeders selecting traits and a Malthusian nature selecting among variants thrown up by chance.
Darwin now had the framework of his theory of natural selection, but he was fully occupied with his career as a geologist and held off writing a sketch of his theory until his book on The Structure and Distribution of Coral Reefs was completed in May Darwin continued to research and extensively revise his theory of natural selection while focusing on his main work of publishing the scientific results of the Beagle voyage.
He tentatively wrote of his ideas to the famous Scottish geologist Charles Lyell in January ; then in June he roughed out a page pencil sketch of his theory. Darwin began correspondence about his theorising with the botanist Joseph Dalton Hooker in January , and by July had rounded out his sketch into a page essay, to be expanded with his research results and published if he died prematurely.
His famous book On the Origin of Species was written for non-specialist readers and attracted widespread interest upon its publication. As Darwin was already an eminent scientist, his findings were taken seriously. The evidence he presented generated scientific, philosophical, and religious discussion.
The debate over the book contributed to the campaign by Thomas Huxley and his fellow members of the X Club to secularise science by promoting scientific naturalism. Within two decades there was widespread scientific agreement that evolution, with a branching pattern of common descent, had occurred, but scientists were slow to give the mechanism of natural selection the significance that it deserved.

Every species is fertile enough that if all offspring survived to reproduce the population would grow. Despite periodic fluctuations, populations remain roughly the same size.
Resources such as food are limited and are relatively stable over time.
