Evolution and natural selection are the same thing
- Natural selection is a major mechanism that causes evolution in a
population and one that results in adaptation, but it is not the only
process that causes evolution.
Evolution occurs slowly
- The rate of evolution is controlled by a number of factors one of
which is generation time. Bacteria and viruses evolve quickly.
Selection acts on individuals; therefore, individuals evolve
- Selection does not act on individuals but actually population.
Individuals do not change but the makeup of the population does.
Natural selection is not directed
- Natural selection does not cause perfection. It is mindless and
mechanistic. It selects among whatever variations exist within the
population.
Because it is driven by mutation, evolution by natural selection is a
random process
- Mutations occur randomly however natural selection is not random.
It selects individuals in a population with certain traits. This results in
adaptation and increased fitness over time.
Favourable traits arise in response to a change in environment
- Traits that increase fitness of an individual in a population already
