Answer to Question #19951 in Biology for tina

Question

populations of organisms are constantly evolving,which means they are always:
1-improving
2-at equilibrium
3-becoming more like humans
4-getting bigger
5-changing
which one of these answers is the right one?

Answer 1

5-changingBecause evolution is the change in the inheritedcharacteristics of biological populations over successive generations. This means that populations are always changing.Evolutionary processes acting during a long time can leadto the formation of new species and further divergence and to the extinction of entire species. So we can't say that populations are always improving.
