Evolution explains changes in allele frequencies over time. As these changes in allele frequencies build up over time, a population can no longer be considered to be the same species it once was.
Depending on generation lengths, these changes can take days or millions of years. When these times lengths are extremely long, it is hard to determine when exactly you would say one example is species A while another is species B; however, we have observed speciation (put "observed instances of speciation" into Google) and have many other evidences that speciation occurs. For example, ERVs, biogeographical distribution of species, computational genomics and proteomics, vestigial genes and structures, ring species, and more.

Is extinction a part of the theory of evolution?
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
Are there multiple theories of evolution?
No- only one. Darwin's Theory of Evolution: •Natural Selection says that better qualities of a specie goes to the next generation and the species becomes better over time; the species that fitted the nature best; served to make new species through mutation and cross breeding.
What statement represent the major concept of the biological theory of evolution?
The major concept of the biological theory of evolution is that species change over time through natural selection, genetic drift, and other mechanisms. This process results in the adaptation and diversification of organisms to their environments, ultimately leading to the formation of new species.
Does the existence of intermediate forms support or not support the theory of evolution?
The existence of intermediate forms supports the theory of evolution. These transitional forms provide evidence of how species have evolved over time through gradual changes and adaptations. They demonstrate the idea of common ancestry and the gradual development of new species from ancestral ones.
What states that changes in species happen slowly over long time periods?
The theory of evolution, proposed by Charles Darwin, states that changes in species occur gradually over long periods of time through the process of natural selection. This theory suggests that new species arise from the accumulation of small, incremental changes in traits that are advantageous for survival and reproduction.
How might evolution theory account for this phenomenon?
Evolutionary theory can account for the phenomenon of a new species. This is because different species can evolve from a common ancestor.
What is theory of evolution that deals with an organism's changing and developing into a new species is called?
In Darwin's exact words. The theory of evolution by means of natural selection.
Does biological evolution answer the question of the beginning of species?
Yes, evolutionary theory explains how new species emerge from existing species.

The theory that evolution occurs slowly but steadily is called?
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."
