___________ is known as the type of isolation that occurs when a population's gene pool diverges and two species form

__________ is known as the evolution toward different traits in related species

Which theory explains how Pangea occurred?

The geologic time scale is arranged from largest time span to smallest time span. Pick the correct arrangement from largest to smallest.

The breeding seasons of the eastern spotted skunks and western spotted skunks occur at different times of the year. The two skunks cannot mate because the eastern spotted skunks breed near the end of winter while the western one breeds in the autumn. Which type of reproductive isolation is this?

It is difficult to distinguish between the eastern meadowlark and the western meadowlark based on their appearance alone, but their calls are quite distinct. The whistle-like call of the eastern meadowlark can be easily distinguished from the flute-like call of its western cousin. This difference serves as a cue and prevents members of both populations from mating with each other. Which type of reproductive isolation is this?

The American toad and Fowler’s toad are not known to mate in the wild because the American toad mates in early summer, while the Fowler’s toad mates in late summer. Which type of reproductive isolation is this?

A mountain range prevents two types of goat from mating, causing the gene pool to become less varied. Which type of reproductive isolation is this?

Male fireflies of a variety of species signal to their female counterparts by flashing their lights in specific patterns. Females will only respond to the signals flashed by their own species, preventing them from mating with other closely related firefly species. Which type of reproductive isolation is this?

Which is NOT a way reproductive isolation happens?

When species evolve because of changes in each other, it is called:

The rapid speciation of one ancestral species into many descendant species is called:

Which theory states that speciation occurs suddenly and rapidly then is followed by long periods of no change?

_______________ is the elimination of a species from earth.

This type of evolution is when similar traits appear in unrelated species.

How old do scientists think the earth is now?

The largest time span of the geologic time scale is the:

What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open late in the day?

Among the finch populations of the Galapagos Islands, the founder effect, reproductive isolation, and competition all contributed to:
