Prevents interbreeding, therefore allows the development of diverging traits without being balanced by mating with the other population.

Why does geographic isolation cause specilation?
It prevents the two populations from interbreeding - APEX
How does reproductive isolation increase isolation?
it stops gene flow
How does reproductive isolation increase the diversity?
It stops gene flow?
How does competition increase stability in ecosystem?
It keeps population balanced. Apex bru
Why do organisms produce more offspring than they need to?
Populations tend to increase in size.
Which increase speciation?
Geographic isolation Low geneflow.

Why does geograpical isolation increase differences between gene pools?
Because they produce with whomever they want which gives them more varieties in a gene pool

How does geographic isolation contribute to the evolution of a new species?
the answer is in page 497 starts where it says over several and ends where it says isolated population... Here is the answer more specific..... It contributes because isolated groups may experience different environments then other species somewhere else where so they will have to adapt to there environment to survive..for example if you put a bird on one island and a bird on another island farther away with a different environment they are both gonna adapt to there environment and become 2 different species Good answer but i think mine might be a little more informational. Also i got this answer in the McGraw Hill Glencoe life science book on page 159 bottom left. Geographic Isolation contributes to evolution because many gene mutations occur. A species has already adapted to that cold environment so that they will change. This will cause the organism to not be able to mate with any other of their old species. This also adds variations to populations. The Key deer, for example, evolved because of geographic evolution 4,000-6,000 years ago. Now the key deer will only be able to mate with other deer that went through the same mutations in geographic evolution.
Which increase the rate of specialtion?

Isolation of phosphobacteria?
Phosphobacteria added to the soil can increase the available phosphorous in the soil. Biochemical companies are working isolation of phosphobacteria in volcanic soils to increase production and potency for use in ground treatments.
Which of the follwing is an effect of the reduction in bird populations?
The largest effect of a reduction in bird populations is the increase in insect populations. Insect populations grow if there are fewer birds around to eat them.
