That's the year Charles Darwin published "The Origin of Species," the book that spelled out the theory of evolution by natural selection.

The process of evolution consists of mechanisms that cause the observed pattern of change. Scala Naturae.

These processes form a continuum that is the history of life on Earth.The theory of evolution is the unifying theory of biology, meaning it is the framework within which biologists ask questions about the living world. The Ukrainian-born American geneticist Theodosius Dobzhansky famously wrote that “nothing makes sense in biology except in the light of evolution.”.

The theory of evolution succeeds in explaining why we see bacteria and mosquitoes becoming resistant to antibiotics and insecticides. It also successfully predicted, for example, that X-ray exposure would lead to thousands of mutations ...Evolutionary science explains the huge diversity of present and past life forms. Heritable variation between particular characteristics (traits) of individuals causes differential reproductive success (fitness), leading to the accumulation of beneficial variations (adaptations) in subsequent generations. Changes in genotype (caused by mutations ...

Recombination DNA changes when chromosomes shuffle, or recombine. This happens normally in the process of making a sperm or an egg. As a result, every new child or offspring inherits a unique assortment of DNA from each parent. Although both children inherited their chromosomes from the same parents, each child got different versions. Selection

Biologists define an acquired characteristic as one that has developed in the course of the life of an individual in the somatic or body cells, usually as a direct response to some external change in the environment or through the use or disuse of a part. Although the theory of evolution generated some controversy when Darwin first proposed it, biologists almost universally accepted it, particularly younger biologists, within 20 years after publication of On the Origin of Species.

The theory of evolution states that the diverse array of organisms on Earth has evolved from a single common ancestor over time. Evolution works through a process known as natural selection. Natural selection makes it more likely for the best-adapted individuals to survive and reproduce. Individuals who reproduce pass their traits on to their ...

A New Evolutionary Synthesis. In 1922, Walter Garstang declared that ontogeny (an individual's development) does not recapitulate phylogeny (evolutionary history); rather, it creates phylogeny. Evolution is generated by heritable changes in development. “The first bird,” said Garstang, “was hatched from a reptile's egg.”.Menu. Home; Evolution 101.

Simpson's primary contention was that the fossil record clearly and inarguably supports Darwin's theory of natural selection. The basic theory of evolution is surprisingly simple. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line.
