Allopatric speciation and sympatric speciation are two factors.
Allopatric speciation occurs when physical barriers are formed, separating the specie. This will cause the specie to evolve at different rates causing a new specie to form.
Sympatric speciation is less likely to occur when comparing it to allopatric. In sympatric speciation is no longer physical but generic. For example a mutation in the genetic order of the specie (which does not happen as often as physical barriers), and a different mating preference/season.
it is TRUE!!
Separation is important in speciation because it isolates populations, preventing gene flow between them. Over time, this isolation can lead to genetic divergence and the accumulation of differences that eventually result in the formation of new species. Thus, separation acts as a key mechanism driving the evolution of biodiversity through speciation.
Actually it is.
A geographic barrier that isolates a population into separate groups, preventing them from interbreeding, is most likely to lead to speciation. Over time, genetic differences can accumulate between the isolated populations, eventually leading to the formation of new species.
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Natural selection seems to be the only selection that can drive speciation with powerful adaptive change. Sexual selection seems to stay within the species and both gene flow and genetic drift do not seem to drive speciation very well.
Sexual Selection.
it is TRUE!!
Adaptation, divergence and speciation.
No
Alopatric speciation.
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
Extinction
Mutation, isolation and natural selection. Google allopatric speciation.

The term that best describes the result of a new species evolving from an existing species is "speciation." This process occurs when populations of a species become reproductively isolated and undergo genetic changes over time, leading to the emergence of distinct species. Speciation can occur through various mechanisms, including allopatric, sympatric, and parapatric speciation.
Evolution is the change in populations of organisms over time while speciation is the direct result of natural selection working to select individuals with traits different enough, but beneficial enough, y drive their alleles into greater frequency in popilations so that new species have a chance of arising; either by anagenesis or phylogenesis.
