What is a divergent evolution pattern?

What is a divergent evolution pattern?

Definition. Divergent evolution represents the evolutionary pattern in which species sharing a common ancestry become more distinct due to differential selection pressure which gradually leads to speciation over an evolutionary time period.

What is the term that describes when an ancestral species evolves into an array of species to fit a number of diverse habitats?

divergent evolution in which ancestral species evolve into an array of species to fit a number of diverse habitats.

What do you call similar structures that result from divergent evolution?

Through divergent evolution, organisms may develop homologous structures. These are anatomically similar structures, which are present in the common ancestor and persist within the diverged organisms, although have evolved dissimilar functions.

What is the pattern of evolution?

Evolution over time can follow several different patterns. Factors such as environment and predation pressures can have different effects on the ways in which species exposed to them evolve. shows the three main types of evolution: divergent, convergent, and parallel evolution.

What pattern shows an adaptive radiation event in the fossil record?

What pattern shows an adaptive radiation event in the fossil record? There is an increasing variety of fossils in a short period of time.

When unrelated species evolve similar characteristics because they live in similar environments?

In evolutionary biology, convergent evolution is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.

How are birds and bats divergent in evolution?

-divergent evolution occurs when populations change as they adapt to different environmental conditions. They become less alike and eventually into two different species. -i.e. birds and bats, they evolved independently and at different times, yet natural selection favored variations suitable for the same environment: air.

How can scientists tell how closely two organisms are related?

Scientists can determine how closely two organisms are by comparing their DNA. If the two species have similar patterns in their DNA, this indicates that the DNA sequence may have been inherited by a common ancestor i.e. the lone wolf travels to find a new territory or breeding partner.

How are two species in the same habitat different?

-i.e. two species may occupy the same habitat but mate or flower at different times of the day, in different seasons, or in different years. reproductive isolation based on structural differences, ‘the parts do not fit’. Sperm of one species may not be able to fertilize the eggs of another species.

How did birds and bats become different species?

They become less alike and eventually into two different species. -i.e. birds and bats, they evolved independently and at different times, yet natural selection favored variations suitable for the same environment: air. Since they do not share a common ancestor birds and bats evolved quite different wings
