How is Evolutionary Trends affect Species Sorting?

Benthic snail larvae are more likely to become isolated and therefore speciate at a higher rate creating more lineages.


When environmental conditions change it is more likely that at least some members of a species will survive if?

When environmental conditions change it is more likely that at least some members of a species will survive if there is variation among the members.


What situations will speciation occur?

Speciation can occur when populations of a species become reproductively isolated, preventing gene flow between them. This can happen through geographic isolation, where populations are separated physically, or through mechanisms like behavioral differences or polyploidy leading to reproductive barriers. Over time, these isolated populations can accumulate enough genetic differences to become distinct species.


Why is the most favorable condition for allopatric speciation a small population at the fringe of the parent population?

A small, isolated population is more likely to change substantially enough to become a new species than a large one.


When environmental conditions change it is more likely that at least some members of a species will survive if they?

there is variation among the members.


When do you call a species endangered versus threatened?

A species is considered endangered when it is at a very high risk of extinction in the near future. A species is considered threatened when it is likely to become endangered in the foreseeable future if threats continue.


Is it true that when some members of a species become isolated they are less likely to form a new species?

Isolation is often the precursor to the generation of a new species or subspecies. Small populations of isolated individuals can go through genetic drift, a condition where a considerable change in the phenotype/genotype of the population occurs in one or two generations. Prolonged isolation could yield substantial change if environmental pressures are different in the isolated region compared to the larger population from which it separated.Snow Leopards are an example of changes in coat thickness, coat color, tail length and fat storage which are adaptations to an alpine environment. Whether the progenitors of the Snow Leopard were isolated from the main population during glaciation, marginalized individuals that migrated where they could fill an unoccupied niche, out competed the previous niche holder or some combinationof these possibilities the result is the Snow Leopard.

Members of the same species would be expected to what?

They would most likely be expected to mate/reproduce. Or am i getting your question wrong?


What would most likely occur if a species is adapted to an environment then the environment changes quickly?

Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.
