Question

How does evolution apply to the use of insecticides and antibiotics?

Answer 1

Answer:

The changes in the environment brought about by antibiotics result in evolutionary changes in the genetic makeup of the bacteria.

Explanation:

The bacteria lose genetic material in order not be affected by the antibiotics. The Beak of the Finch page 260-262.

This is an example of adaptive evolution. Another examples is the blind fish of Death Valley. The fish have lost the genetic information for making eye tissue.

This is a counter example for Neo Darwinian evolution. The loss of information is not an example of Neo Darwinian evolution. Neo Darwinian evolution implies and requires an increase in information.

The development of antibiotic resistance is the result of an adaptation caused by the loss of genetic information. This is a type of evolution but not Neo Darwinian evolution.
