5 Which of the following statements best explains
why geographic isolation can lead to speciation?
A Physical separation of populations reduces
competition for each group.
B Physical separation of populations prevents
interbreeding and mixing of gene pools.
C Physical separation of populations provides
more space for each group’s size to increase.
D Physical separation of populations stresses
the organisms and causes mutations in their
genetic code.

How do species propagate themselves? Pretty hard to do this propagation if you cannot physically interact because of something like an ocean.

How do humans make more humans?

sexual interaction??

anonymous · Answer

Yes.  Now, what does that do? It keeps populations of humans sharing a common gene pool.  I am defining gene pool all the variation in found in all the genomes of a species or population.

Now, if a group of humans magically gets sent to a new planet trillion of light years away from Earth, could the Earth humans and the non-Earth humans share a single gene pool?
