What is the basic theory of evolution?

The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.

How would you describe evolution?

Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

What is the meaning of evolutionary theory?

Definition. Evolutionary theory is the area that focuses on further development and refinement of the modern synthesis of evolution and genetics.

What does the evolutionary theory proposed?

Darwin and a scientific contemporary of his, Alfred Russel Wallace, proposed that evolution occurs because of a phenomenon called natural selection. In the theory of natural selection, organisms produce more offspring than are able to survive in their environment.

What is evolution in your own words?

Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. An example of evolution is how cell phones have changed over time.

What are three definitions of evolution?

b : the action or an instance of forming and giving something off : emission. c(1) : a process of continuous change from a lower, simpler, or worse to a higher, more complex, or better state : growth. (2) : a process of gradual and relatively peaceful social, political, and economic advance. d : something evolved.

What is an example of evolutionary theory?

For example, a phenomenon known as genetic drift can also cause species to evolve. In genetic drift, some organisms—purely by chance—produce more offspring than would be expected. Charles Darwin is more famous than his contemporary Alfred Russel Wallace who also developed the theory of evolution by natural selection.

What is evolutionary theory in government?

The Evolutionary Theory holds that the first governments evolved naturally from the family. Over time one family grew very large and eventually became what is known as a clan, where all of the relations from one large family continue to propagate together.

Which is the best definition of evolution?

What is the theory of evolution most accurately described as?

The theory of evolution is most accurately described as An overcoming explanation supported by much evidence for how populations change overtime Darwin’s mechanism of natural selection required long time spans in order to modify species.

Which scientist is credited for the theory of evolution?

Updated January 26, 2019. Charles Darwin (Feb. 12, 1809 to April 19, 1882) holds a unique place in history as the foremost proponent of the theory of evolution. Indeed, to this day, Darwin is the most famous evolution scientist and is credited with developing the theory of evolution through natural selection.

Who is best known for developing a theory of evolution?

The British naturalist, biogeographer , author, humanitarian, Alfred Russel Wallace (Jan. 8, 1823–Nov. 7, 1913) is best known for developing a theory of evolution through natural selection independently of Charles Darwin.

What are the two theories of evolution?

There are two theories regarding Evolution of Bryophytes: (i) The first theory is known as up-grade or progressive evolution theory, (ii) and the second one is called down-grade or regressive evolution theory.
