Changes that allow an organism to better adapt to its environment will help it survive and have more offspring. Evolution by natural selection is one of the best substantiated theories in the history of science, supported by evidence from a wide variety of scientific disciplines, including paleontology, geology, genetics and developmental biology. More simply put, the theory can be described as "descent with modification," said Briana Pobiner, an anthropologist and educator at the Smithsonian Institution National Museum of Natural History in Washington, D. The theory is sometimes described as " survival of the fittest ," but that can be misleading, Pobiner said.
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  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.

|Darwin and Wallace rewrite the theory of evolution Darwin and Wallace presented their accounts of evolution at the same meeting Darwin finally went public with his groundbreaking theory of evolution by natural selection, while making sure that Wallace received some credit.|
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. 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.Charles Darwin and Evolution Charles Darwin was born in England in He enjoyed studying biology and geology, and in , he got the opportunity to serve as a naturalist on a trip around the.
Darwin's Theory of Evolution - Natural Selection While Darwin's Theory of Evolution is a relatively young archetype, the evolutionary worldview itself is as old as antiquity. Ancient Greek philosophers such as Anaximander postulated the development of life from non-life and the evolutionary descent of .
Charles Darwin was a naturalist who observed many aspects of nature and compiled his ideas into a theory called natural selection. More specifically, his theory is called the theory of evolution by natural selection because it . Darwin and Natural Selection.
Most educated people in Europe and the Americas during the 19th century had their first full exposure to the concept of evolution through the writings of Charles grupobittia.comy, he did not invent the idea. That happened long before he was born. However, he carried out the necessary research to conclusively document that evolution .
Oct 06, · Darwin, Then and Now - a chronicle of the rise and fall of the theory of evolution. The book focuses on who Darwin was, what motivated him, what he said, and what scientists have discovered since the publication of The Origin of Species in The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" in , is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits.
