In his book, Darwin describes how organisms evolve over ...In biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

The theory of evolution by natural selection is attributed to 19th century British naturalist Charles Darwin. The theory is widely accepted based on fossil records, DNA sequencing, embryology, comparative anatomy and molecular biology. Darwin’s finches are examples of evolutionary adaptation.Cell theory is one of the great triumphs of biology, and its history ought to occupy a more central position than it currently does. As with all science, ideas about the nature of life started with the Greeks. Thales’ idea that everything is made of water in different forms, in a very general way foreshadows the cell theory. Yet there was little progress in …Cosmologists have devised more than 30 additional takes on the anthropic principle [source: Stenger].They include the quantum physics-flavored participatory anthropic principle, which states that no universe can be real until it is observed, and the final anthropic principle, which holds that intelligence is a necessary property of the universe; once created it can never be destroyed.The science of evolution The process of evolution Evolution as a genetic function The concept of natural selection.

It explains and unifies all of biology. Darwin’s theory actually contains two major ideas: One idea is that evolution occurs. In other words, organisms change over time.The Theory of Evolution presents a series of chapters by experts seeking this integration by addressing the current state of affairs across numerous fields within evolutionary biology, ranging from biogeography to …Variation. In evolution, the fate of an individual depends on which features it has. Each human, for example, inherits a unique combination of thousands of different features, such as eye color, blood type and sensitivity to certain tastes. Some variants, or versions of a feature, may help an organism to survive. Others may be harmful.
