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

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 combination
of these possibilities the result is the Snow Leopard.

In which species is egg temperature most likely to affect the gender of the young?
Leatherback turtle
What organisms is most likely 50 meters in size?
Redwood trees are one species.
Describe conditions that could make a new island a likely place for adaptive radiation?
Conditions that could make a new island a likely place for adaptive radiation would include being near a mainland so organisms can migrate as well as geographic isolation which prevents the splinter populations from breeding with the parent population on the mainland.
What is the concept of survival of the fittest?
AnswerSurvival of the fittest, or Social Darwinism, refers to the characteristics of the fittest members of a species (in terms of their ability to survive in a given environment and produce offspring) will be passed on and become more common in the species. It does not refer to the fitness of individual organisms, precisely, but rather to the fitness of the species as a whole.Charles Darwin defined natural selection as relating to the members of the species who were the most successful in survival skills (ie finding food, avoiding enemies, living to adulthood were the ones who had children and so propagated the species with their genes).It should be noted that the Charles Darwin didn't use the term 'survival of the fittest', it was coined by biologist, sociologist, and author Herbert Spenser in his Principles of Biology published in 1864, five years after Darwin's On The Origin of Species. He used the term in his discussion of Darwin's book.In the context of 'survival of the fittest', the word 'fittest' means best suited to its environment.
According to the theory of natural selection a species that lacks the variations necessary to adapt to a changing environment will most likely do what?
Go extinct.
When some members of a species become isolated they are less likely to become a new species true or false?
False.
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 happens when species overproduce offspring?
When a species overproduces it makes it less likely for members of the same species to survive.
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.
Two species have the same niche. What is the most likely outcome when one species is the superior competitor?
The other species will become extinct
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.
What situations will speciation occur?
Speciation is the process of a new species developing. Speciation can occur from a geographical split in the species, Species can split in the same area if they start depending on different foods.
What is most likely to happen to a population of mice that becomes isolated on an island?
Many different species will form as they evolve to fill different niches on the island.
When do you call a species endangered versus threatened?
In order to be considered endangered, the species is in danger of extinction. To be considered threatened, the species has to be likely to become an endangered species.
Is a species that is likely to become extinct if protective measures are not taken immediately?
threatned
When are tigers likely to become extincy?
2015 for some species but 2020 if they are lucky.
