Question 5

Place the steps in the process of natural selection in the correct order:

1) over generations, a larger proportion of the population becomes adapted to the environment.
2) The population produces more offspring than the environment can support.
3) Members of a population have heritable variations.
4) The more adapted individuals survive and reproduce to a greater extent than those individuals lacking adaptions.
