He was the grandson of two prominent abolitionists: Erasmus Darwin on his father's side, and Josiah Wedgwood on his mother's side. Painting of seven-year-old Charles Darwin in Both families were largely Unitarianthough the Wedgwoods were adopting Anglicanism.

Robert Darwin, himself quietly a freethinkerhad baby Charles baptised in November in the Anglican St Chad's Church, Shrewsburybut Charles and his siblings attended the Unitarian chapel with their mother.

The eight-year-old Charles already had a taste for natural history and collecting when he joined the day school run by its preacher in That July, his mother died.

From Septemberhe joined his older brother Erasmus attending the nearby Anglican Shrewsbury School as a boarder. Darwin found lectures dull and surgery distressing, so he neglected his studies.

He learned taxidermy in around 40 daily hour-long sessions from John Edmonstonea freed black slave who had accompanied Charles Waterton in the South American rainforest. One day, Grant praised Lamarck 's evolutionary ideas. Darwin was astonished by Grant's audacity, but had recently read similar ideas in his grandfather Erasmus' journals.

He learned the classification of plants, and assisted with work on the collections of the University Museumone of the largest museums in Europe at the time. As Darwin was unqualified for the Triposhe joined the ordinary degree course in January His cousin William Darwin Fox introduced him to the popular craze for beetle collecting; Darwin pursued this zealously, getting some of his finds published in James Francis Stephens ' Illustrations of British entomology.

He became a close friend and follower of botany professor John Stevens Henslow and met other leading parson-naturalists who saw scientific work as religious natural theologybecoming known to these dons as "the man who walks with Henslow". When his own exams drew near, Darwin applied himself to his studies and was delighted by the language and logic of William Paley 's Evidences of Christianity [32] In his final examination in January Darwin did well, coming tenth out of candidates for the ordinary degree.

He studied Paley's Natural Theology or Evidences of the Existence and Attributes of the Deity first published inwhich made an argument for divine design in natureexplaining adaptation as God acting through laws of nature. Inspired with "a burning zeal" to contribute, Darwin planned to visit Tenerife with some classmates after graduation to study natural history in the tropics.

In preparation, he joined Adam Sedgwick 's geology course, then on 4 August travelled with him to spend a fortnight mapping strata in Wales. The ship was to leave in four weeks on an expedition to chart the coastline of South America.

As FitzRoy had intended, Darwin spent most of that time on land investigating geology and making natural history collections, while HMS Beagle surveyed and charted coasts. Most of his zoology notes are about marine invertebrates, starting with plankton collected in a calm spell.

Natural selection - Wikipedia Coloration evidence for natural selection InCharles Darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. He defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
On the Origin of Species - Wikipedia Despite periodic fluctuations, populations remain roughly the same size fact. Resources such as food are limited and are relatively stable over time fact.
About Ecalpemos Summary Darwin now focuses on natural selection, returning to his discussion of a breeder selecting desired characteristics for animals. If breeders can select characteristics they wish to breed in their animals and perpetuate these characteristics in their domestic populations, is it possible for nature to act in the same way?

FitzRoy had given him the first volume of Charles Lyell 's Principles of Geology, which set out uniformitarian concepts of land slowly rising or falling over immense periods, [II] and Darwin saw things Lyell's way, theorising and thinking of writing a book on geology.

He identified the little-known Megatherium by a tooth and its association with bony armour, which had at first seemed to him to be like a giant version of the armour on local armadillos.

The finds brought great interest when they reached England. He read Lyell's second volume and accepted its view of "centres of creation" of species, but his discoveries and theorising challenged Lyell's ideas of smooth continuity and of extinction of species.

Three Fuegians on board had been seized during the first Beagle voyagethen during a year in England were educated as missionaries. Darwin found them friendly and civilised, yet at Tierra del Fuego he met "miserable, degraded savages", as different as wild from domesticated animals.

Unlike his scientist friends, he now thought there was no unbridgeable gap between humans and animals. The Fuegian they had named Jemmy Button lived like the other natives, had a wife, and had no wish to return to England.

High in the Andes he saw seashells, and several fossil trees that had grown on a sand beach. He theorised that as the land rose, oceanic islands sank, and coral reefs round them grew to form atolls. He heard that slight variations in the shape of tortoise shells showed which island they came from, but failed to collect them, even after eating tortoises taken on board as food.

Inception of Darwin's theory While still a young man, Charles Darwin joined the scientific elite. When the ship reached Falmouth, Cornwallon 2 OctoberDarwin was already a celebrity in scientific circles as in December Henslow had fostered his former pupil's reputation by giving selected naturalists a pamphlet of Darwin's geological letters.

Zoologists had a huge backlog of work, and there was a danger of specimens just being left in storage. Owen's surprising results included other gigantic extinct ground sloths as well as the Megatheriuma near complete skeleton of the unknown Scelidotherium and a hippopotamus -sized rodent -like skull named Toxodon resembling a giant capybara.

The armour fragments were actually from Glyptodona huge armadillo-like creature as Darwin had initially thought. On the same day, he presented his mammal and bird specimens to the Zoological Society.

The ornithologist John Gould soon announced that the Galapagos birds that Darwin had thought a mixture of blackbirds" gros-beaks " and fincheswere, in fact, twelve separate species of finches.

On 17 February, Darwin was elected to the Council of the Geological Society, and Lyell's presidential address presented Owen's findings on Darwin's fossils, stressing geographical continuity of species as supporting his uniformitarian ideas. Darwin stayed with his freethinking brother Erasmuspart of this Whig circle and a close friend of the writer Harriet Martineauwho promoted Malthusianism underlying the controversial Whig Poor Law reforms to stop welfare from causing overpopulation and more poverty.Evolutionists deliberately tolerate knowingly fraudulent pro-evolution evidence in School Textbooks.

New Textbooks purchased by schools in the last year are full of fraud and lies to promote evolution. School Teachers and professors know the material is fraud, but still teach it.

Misleading. Mr. Darwin has called 'natural selection', or the preservation of favoured races in the struggle for life." Although many of Darwin’s contemporaries urged him to use “s urvival of the fittest” as a synonym for natural selection in the Origin, Darwin consistently resisted these entreaties believing Spencer’s phrase simplistic and misleading.
