Darwin was young and generally in good health, though six months previously he had been ill for a month near Valparaiso, but in 1837, almost a year after he returned to England, he began to suffer intermittently from a strange group of symptoms, becoming incapacitated for much of the rest of his life.

Lyell and Hooker were instrumental in arranging the peaceful co-publication of the theory of natural selection by Darwin and Alfred Russel Wallace in 1858: each had arrived at the theory independently.

Quite strong remarks: no doubt Darwin resented Lyell's repeated suggestion that he owed a lot to Lamarck, whom he ( Darwin ) had always specifically rejected.

John Clements Wickham named the region " Port Darwin " in honour of their former shipmate Charles Darwin, who had sailed with them on the ship's previous voyage which had ended in October 1836.

For example, at the time that Darwin first published On the Origin of Species by Means of Natural Selection ( 1859 ), no remains of human ancestors had yet been found.

Darwin did not use the term in Origin of Species until its sixth edition in 1872, ( though earlier editions did use the word " evolved ") by which time Herbert Spencer had given it scientific currency with a broad definition of progression in complexity in 1862.

Faunal succession was one of the chief pieces of evidence cited by Darwin that biological evolution had occurred.

His grandfather, an amateur naturalist by the name of Walter Drawbridge Crick ( 1857 – 1903 ), wrote a survey of local foraminifera ( single-celled protists with shells ), corresponded with Charles Darwin, and had two gastropods ( snails or slugs ) named after him.

Other theories included the pangenesis of Charles Darwin ( which had both acquired and inherited aspects ) and Francis Galton's reformulation of pangenesis as both particulate and inherited.

However, the quote in context shows that Darwin actually had a very good understanding of the evolution of the eye.

Lyell's books had widespread influence, not least on the up and coming young geologist Charles Darwin who read them with enthusiasm during his voyage on the Beagle, and has been described as Lyell's first disciple.

Studies of Charles Darwin's notebooks have shown that Darwin arrived separately at the idea of natural selection which he set out in his 1859 book On the Origin of Species, but it has been speculated that he may have had some half-forgotten memory from his time as a student in Edinburgh of ideas of selection in nature as set out by Hutton, and by William Charles Wells and Patrick Matthew who had both been associated with the city before publishing their ideas on the topic early in the 19th century.

In 1999, his Australian tour was cut short when he had to be hospitalized in Darwin with viral meningitis.

Darwin was a physician and poet who had studied at Cambridge and Edinburgh ; Boulton had left school at fourteen and started work in his father's business making metal goods in Birmingham at the age of 21.

Proponents argue that the central point, that the gene is the unit of selection, usefully completes and extends the explanation of evolution given by Charles Darwin before the basic mechanisms of genetics were understood.

Work concerning female behavior in many species of animals has sought to confirm Darwin ’ s basic idea of female preference for males with certain characteristics as a major force in the evolution of species.

The Lunar Society included industrialists such as Samuel Galton, Jr. as well as intellectuals such as Erasmus Darwin and Joseph Priestley ; scientific lecturers such as John Warltire and Adam Walker communicated basic Newtonian principles widely to the town's manufacturing classes ; and men such as Matthew Boulton, James Keir, James Watt and John Roebuck were simultaneously highly regarded both as scientists and as technologists, and in some cases also as businessmen.

For many years the phenomenon was labeled " preadaptation ," but since this term suggests teleology, which is contrary to a basic principle of natural selection, it has been replaced by other terms in the years after Darwin.

It's suggested that his theory is based on the beliefs of Charles Darwin as he believed that when animals ' play ' they are practising basic instincts, such as fighting, for survival.

Mivart wrote wishing " with all my heart that we did not differ so widely ", but challenging Darwin to debate the basic metaphysics underlying science, from his Roman Catholic position writing that " while combatting ( as duty compels me to do ) positions you adopt, I am not so much combatting you as others to whose view your scientific labours give additional currency.

Biology CP-A basic study of organic Biology and basic Chemistry including study the cell and Darwin ’ s theory of evolution.

He is best known for independently proposing a theory of evolution due to natural selection that prompted Charles Darwin to publish his own theory.

Charles Darwin proposed the theory of universal common descent through an evolutionary process in On the Origin of Species, twice stating the hypothesis that there was only one progenitor for all life forms and ending with " There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one ".

* Charles Darwin ( 1809 – 1882 ), English naturalist and writer, best known as the originator of the theory of biological evolution by natural selection

" Creationists use the term Darwinism, often pejoratively, to imply that the theory has been held as true only by Darwin and a core group of his followers, whom they cast as dogmatic and inflexible in their belief.

* 1831 – Charles Darwin embarks on his journey aboard the HMS Beagle, during which he will begin to formulate the theory of evolution.

While the Darwin Awards are named after Charles Darwin, due to his theory of natural selection, there is no evidence that the stories depicted actually represent the removal of " judgement impairment genes " from the gene pool.

* 1959 " Darwin and the evolutionary theory in Biology ".

They are noted for their association with Charles Darwin, whose observation of animals here during the voyage of the Beagle led to his formation of the theory of natural selection as a means of evolution.

Darwin applied the theory of evolution and sexual selection to humans when he published The Descent of Man in 1871.

In Crick ’ s view, Charles Darwin ’ s theory of evolution by natural selection, Gregor Mendel ’ s genetics and knowledge of the molecular basis of genetics, when combined, revealed the secret of life.

Charles Darwin was influenced by Lyell's Principles of Geology, which explained both uniformitarian methodology and theory.

When Charles Darwin proposed his theory of evolution in 1859, one of its major problems was the lack of an underlying mechanism for heredity.

He also drafted an article on The part played by labour in the transition from Ape to Man, apparently a theory of anthropogenesis which would integrate the insights of Marx and Charles Darwin.

While he did not originate the term, Charles Darwin identified the argument as a possible way to falsify a prediction of the theory of evolution at the outset.

In an often misquoted passage from On the Origin of Species, Charles Darwin appears to acknowledge the eye's development as a difficulty for his theory.

* 1858 – Charles Darwin receives a paper from Alfred Russel Wallace that includes nearly identical conclusions about evolution as Darwin's own, prompting Darwin to publish his theory.

This double-barreled inheritance of Wedgwood's money gave Charles Darwin the leisure time to formulate his theory of evolution.

The modern theory of natural selection derives from the work of Charles Darwin in the nineteenth century.

While often seen as rejecting Darwin's theory of branching evolution for a more linear Lamarckian " biogenic law " of progressive evolution, this is not accurate: Haeckel used the Lamarckian picture to describe the ontogenic and phylogenic history of the individual species, but agreed with Darwin about the branching nature of all species from one, or a few, original ancestors.

The second important process is the theory of evolution by Darwin in mid-century ( which decisively influenced the work of Ratzel, who had academic training as a zoologist and was a follower of Darwin's ideas ) which meant an important impetus in the development of Biogeography.
