They become more and more different over time.

What are the two factors that account for diversity of species?
The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).

How does allopatric speciation occur?
Allopatric speciation: ( other country ) A speciation event that is facilitated geographically. A population is split along geographic lines, mountains, rivers, and the now separate gene pools vary in allele frequency over time enough to , possibly, have two new species arise. Sympatric speciation: ( same country ) An in place speciation event where a sub-population within a population begins to vary their alleles from the main population. Perhaps a slight temporal, or water level difference, or mating differences can facilitate this. This speciation event is still a matter of contreversy in biology. Simplified explanations.
How do these effects on the gene pods lead to speciation?
Effects on gene pools, such as mutations, natural selection, and genetic drift, can lead to speciation by altering the genetic makeup of populations over time. When populations become isolated, either geographically or behaviorally, these genetic changes accumulate, reducing gene flow between them. As adaptations to different environments or ecological niches occur, distinct traits may emerge, eventually leading to reproductive barriers. This divergence can result in the formation of new species, a process known as speciation.
Why does geographic isolation cause separation?
geographic isolation is when a physical barrier divides a population and they can no longer reproduce, reproductive isolation is when a species can no longer reproduce offspring. hope this helps!
How does temporal isolation contribute to the process of speciation?
Temporal isolation, a type of reproductive isolation, occurs when two species reproduce at different times, such as different seasons or times of day. This prevents interbreeding between the species, leading to genetic divergence and ultimately contributing to the process of speciation by creating separate gene pools.

What characterizes speciation in new areas such as recently formed island?
Speciation in new areas, like recently formed islands, is often driven by geographic isolation and genetic drift. Small founder populations can lead to rapid divergence in gene pools, creating new species adapted to the unique island environment. Natural selection and genetic mutations also play a role in speciation on new islands.
How are speciation and microevolution different?
Evolution and speciation. ( microevolution is imprecise ) Alleles can change over time in a population of organisms without any great change in the phenotype or behavior of a species. Then, to keep it simple, a geographic barrier arises between portions of the population and they can no longer interbreed, Mutations happen in the separate populations and evolution can take two different paths now with natural selection driving the winnowing of variations so that adaptive change is happening in the immediate environment of the sundered populations. Given enough time the two populations gene pools will have such a variance in the alleles contained in those two gene pools that two different species will arise.
What mechanism might have affected the gene pools of the organism populations that remained in the areas damage by the Exxon Valdez ail spill?
speciation
How does natural selection explain specialization?
It doesn't per se. Speciation occurs usually when two gene pools are isolated long enough by geography or by separate selective pressures that one group becomes able to reproduce with the other with difficulty, and eventually not at all. Horses can mate with zebras and a few other animals for instance, but produce sterile offspring. Speciation has been observed in nature many times, and forced to occur in the laboratory. Google "instances of speciation" for examples.
How can isolation of groups be involved in speciation?
Speciation is the evolution of new species from existing species and that is what has happened here. If a species was split up due to some sort of natural disaster, each party would evolve on their own because of the isolation. They will adapt to the new environment and eventually develop a new gene pool - this is when a new species has developed.
What happens when blood pools in the veins?
Varicose veins form when blood pools in the veins.
Which mechanism might have affected the gene pools of the organism populations that remained in the areas damaged by the Exxon Valdez oil spill?
Genetic Drift
What is allopatric evolution?
think Darwin's finches and galapagos tortoises... speciation that occurs when biological populations of the same species become isolated due to geographical changes such as mountain building or social changes such as emigration. The isolated populations then undergo genotypic and/or phenotypic divergence as: (a) they become subjected to different selective pressures, (b) they independently undergo genetic drift, and (c) different mutations arise in the populations' gene pools.[1]
