Question

how does geographic isolation lead to reproductive isolation?

what factors influence a species chances of adapting successfully to change in its environment?

why is the pace of human-driven evolution faster then that of natural evolutionary processes?

Answer 1

Answer:  

1.  How does geographic isolation lead to reproductive isolation?  The geographical isolation is the physical separation of two populations by the geographical barriers. This occurs through adaptive radiation and allopatric speciation. The reproductive isolation is the separation of two populations of the same species, preventing interbreeding and production of a fertile offspring

2.  What factors influence a species chances of adapting successfully to change in its environment?  Rate of environmental change, genetic variation, population size, and generation time are factors that influence a species' chances of adapting successfully to a change in its environment.

3.  Why is the pace of human-driven evolution faster then that of natural evolutionary processes?  Using genetic engineering techniques, scientists can now copy genes from a species with some desirable trait, such as rapid growth or disease resistance. However, natural evolution occurs very slowly
