Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
The Magic of Reality: How We Know What's Really True [1][2] The Greatest Show on Earth: The Evidence for Evolution is a 2009 book by British biologist Richard Dawkins, which was released on 3 September 2009 in the UK and on 22 September 2009 in the US. [3] It sets out the evidence for biological evolution, and is Dawkins's 10th book, following ...
Lineage (evolution) – Sequence of populations, organisms, cells, or genes that form a line of descent. Molecular phylogenetics – Branch of phylogeny that analyzes genetic, hereditary molecular differences. Most recent common ancestor – Most recent individual from which all organisms in a group are directly descended.
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits. Genetic changes include mutations, which are caused by damage or replication ...
The Structure of Evolutionary Theory (2002) is Harvard paleontologist Stephen Jay Gould 's technical book on macroevolution and the historical development of evolutionary theory. [1] The book was twenty years in the making, [2] published just two months before Gould's death. [3] Aimed primarily at professionals, [4] the volume is divided into ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Tree of life (biology) The tree of life or universal tree of life is a metaphor, conceptual model, and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin 's On the Origin of Species (1859). [1]
e. Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity—in the ideas of the ancient Greeks, Romans, Chinese, Church Fathers as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late 17th century, two ...
