What are some theories of Darwinism?

Answer 1

The theories are evolution deal with the fact that every being on the planet today came from a now-extinct species. This goes for humans as well. Scientists believe that humans evolved from now-extinct mammals during the Late Cretaceous period. Evidence proves people came from a member of the gibbon family.

Answer 2

Your question is a bit too broad. There is actually just one Theory of Evolution, that encompasses many different biological disciplines. Some people, particularly Creationist or Intelligent Design advocates, try to separate Evolution in Macro-Evolution and Micro-Evolution, but that is really a false division invented to forward there religious agenda.

Answer 3

I'll assume the question is about the different areas of study within evolution.

This is difficult question because Evolution is not a branch within Biology, Its a scientific theory within the branch of genetics, the science of acquired traits passed down from generation to generation.

Answer 4

Within the framework of evolutionary theory, there exist numerous hypotheses trying to account for how humans evolved from its tree-dwelling ape ancestors. Some have our bipedal gait developing from a knuckle-dragging stance as tribes of apes were forced to migrate into the savannas of Africa; some claim our furless skin is the result of a period in which our ancestors dwelled near waters, subsisting almost entirely on fish caught by hand; some claim that our large brains are the result of a run-away process started by the increasingly complex social interactions within tribes of ape. The number of different hypotheses explaining (parts of) human evolution is too great to list them in a single answer.

Answer 5

Big Bang Theory (This is the ultimate Theory of Evolution, as it states that everything we know that is in this universe arose from an initial point of condensed energy, which cooled and expanded over time and materialized into hydrogen. From there, stars formed from the hydrogen and through nuclear fusion created everything else in the universe. Everything we know and see today evolved from that initial point of energy and subsequent cloud of hydrogen gas).

Examples of Evolution:

Stellar Evolution

Cosmic Evolution

Biological Evolution

Divine Theory <---- (This was put here by the author, however there is no such thing as a scientific theory called "Divine Theory". Any consideration that there is a divine creator is a belief-based assumption that is categorically and fundamentally unscientific in nature)

Answer 6

Technically there can be no more than one scienctific theory at a time. A theory is the currently accepted science explanation for a phenomena. The current theory is a variant of Darwin and Wallace's Theory of Evolution by Natural Selection.

Back when Darwin postulated this (as a hypothesis in modern science nomenclature) it contented with various other explanations like Lamarkian Evolution. Lamarkian evolution has been thoroughly disproven since.

The modifications (often called the Modern Synthesis) incorporate our updated understanding of biology, especially genetics.

The basic theory stands.

Within a population of organisms, there is some inheritable variation. When this variation results in diffrent survival or reproductive sucess, the organisms with that variation will dominate, and over many generations the accumulation of these variations will result in changes to population that give rise to new species.

We now know the mechanisms of the variation, and a more thorough understanding of the selection processes. But the basic theory is still the same as it was in the middle of the 19th century.

Answer 7

Three of the commonly known theories of Darwinism include the theory of descent, the theory of evolution, and the theory of selection. Naturally, all three of these theories reference the mechanics of how evolution and survival of the fittest work.

Answer 8

Macro and micro. Do not kid yourself however, they are nothing alike.
