Concept called gradualism. Not hypothesis, as it has been tested and confirmed, especially among the " little shellies. "
Others have said twice: it is called Punctuated Equilibrium.
That theory is called punctuated equilibrium.
natural selection
This is the concept of gradualism.
punctuated equilibrium
This is the concept of gradualism.
Founder effect
Darwin's classic theory of evolution assumed that evolution is a slow, contunuous process, by which new species evolve and emerge. This is referred to at times as "organic evolution" and the "synthetic theory of evolution", or just the Darwinian theory of evolution. A newer theory, proposed originally by Niles Eldridge and Stephen Jay Gould is known as "punctuated equilibria", a model in which the evloution of new species occurs only periodically, in relatively rapid spurts. See "Time Frames the Rethinking of Darwinian Evolution and the Theory of Punctuated Equilibraia, Simon & Schuster, 1985"AnswerThe slow, constant process has also been called "gradualism."
The smallest unit in which evolution occurs is a population.
genetic drift
It's called 'centripetal acceleration', whether or not the speed is constant or the path circular.
The process where organisms evolve through time is called evolution. This natural phenomenon occurs as a result of changes in the environment.
