I told another little boy I believe it was [William Allport] Leighton, who afterwards became a well-known lichenologist and botanistthat I could produce variously coloured polyanthuses and primroses by watering them with certain coloured fluids, which was of course a monstrous fable, and had never been tried by me. Case's school, remembered Darwin bringing a flower to school one day and saying his mother had told him you could find out a plant's name by looking inside its blossoms. Leighton told Darwin's son Francis, "This greatly roused my attention and curiosity, and I inquired of him repeatedly how this could be done? For instance, I once gathered much valuable fruit from my father's trees and hid it in the shrubbery, and then ran in breathless haste to spread the news that I had discovered a hoard of stolen fruit.
Fossil record[ edit ] Research in the field of paleontologythe study of fossils, supports the idea that all living organisms are related. Fossils provide evidence that accumulated changes in organisms over long periods of time have led to the diverse forms of life we see today.
The Writings of Charles Darwin on the Web An online archive of many of Darwin's books, articles, and letters. It also has a brief introduction to his life. Timeline of the life of Charles Robert Darwin. by Janet Browne & John van Wyhe. 12 February Born in Shrewsbury, England, the son of Robert Waring Darwin and Susannah, nee Wedgwood. In the summer goes to Gros, near Abegele, in Wales, for sea-bathing with family, some of his earliest recollections coming from this.

A fossil itself reveals the organism's structure and the relationships between present and extinct species, allowing paleontologists to construct a family tree for all of the life forms on Earth.
Cuvier noted that, in sedimentary rockeach layer contained a specific group of fossils. The deeper layers, which he proposed to be older, contained simpler life forms.
He noted that many forms of life from the past are no longer present today. As a result, the general idea of catastrophism has re-emerged as a valid hypothesis for at least some of the rapid changes in life forms that appear in the fossil records. A very large number of fossils have now been discovered and identified.
These fossils serve as a chronological record of evolution. The fossil record provides examples of transitional species that demonstrate ancestral links between past and present life forms. The implication from such a find is that modern reptiles and birds arose from a common ancestor.
Convergent evolution and Divergent evolution The comparison of similarities between organisms of their form or appearance of parts, called their morphologyhas long been a way to classify life into closely related groups.
This can be done by comparing the structure of adult organisms in different species or by comparing the patterns of how cells grow, divide and even migrate during an organism's development. Taxonomy[ edit ] Taxonomy is the branch of biology that names and classifies all living things.
Scientists use morphological and genetic similarities to assist them in categorising life forms based on ancestral relationships.
For example, orangutansgorillaschimpanzeesand humans all belong to the same taxonomic grouping referred to as a family—in this case the family called Hominidae. These animals are grouped together because of similarities in morphology that come from common ancestry called homology.
Strong evidence for evolution comes from the analysis of homologous structures: The forelimbs of a human, catwhaleand bat all have strikingly similar bone structures.
However, each of these four species' forelimbs performs a different task. The same bones that construct a bat's wings, which are used for flight, also construct a whale's flippers, which are used for swimming.
Such a "design" makes little sense if they are unrelated and uniquely constructed for their particular tasks.First published in , Charles Darwin's theory of evolution inalterably transformed our view of the history of life on the planet - and along with it, how we understand ourselves, our origins, and our place in .

Having published On the Origin of Species as an abstract of his theory, he pressed on with experiments, research, and writing of his "big book".Known for: The Voyage of the Beagle, On the Origin of Species.
An Introduction to the Life of Charles Darwin.
In , Darwin married Emma Wedgwood, his cousin, and they moved in to a house in London where Darwin could focus on his work. Unfortunately, his health started to fail mysteriously, so they moved to the country. They lived in a small village where Darwin could find peace and quiet.

In this brilliant presentation of a revolutionary thinker's life, the picture book becomes an . Charles Darwin’s theory of evolution by natural selection is the foundation upon which modern evolutionary theory is built. The theory was outlined in Darwin’s seminal work On the Origin of Species, published in Although Victorian England (and the rest of the world) was slow to embrace natural selection as the mechanism that drives evolution, the concept of evolution itself gained.

Very helpful but not among the very best; adequately produced, at least. Charles Robert Darwin (February 12, – April 19, ) was a British naturalist who achieved fame as originator of the theory of evolution through natural selection..
Considered the "father of evolutionary theory," Darwin made two contributions of enormous impact to the idea of evolution.
On the Origin of Species. This, certainly the most important biological book ever written, has received detailed bibliographical treatment in Morse Peckham's variorum edition,
