Question 1

If a changing environment increases rates of evolution,why do we see an increase in extinction rates following rapid global catastrophes?

Accepted Answer

Either the change is too swift to allow population time to evolve or the extinctions of some species opens up niches for other species to evolve to fill.

Question 2

How can the use of chemical control agents (antibiotics,herbicides,pesticides)lead to their decreased effectiveness?

Accepted Answer

By changing the environment,these chemicals selectively kill only the bacteria,weeds,and pests that are not immune to them,leaving mostly those with a natural immunity.The resistant individuals survive and reproduce giving rise to a new generation that may also be resistant to the drug.Eventually the chemical is no longer effective against any of them.

Accepted Answer

A) It is accurate because they are the ones that mechanisms of evolution act upon.
