Steps involved in natural selection include:
1) Differing survival rates when faced with environmental challenges.
2) Preservation of genetic traits of best-adapted offspring.
3) Overproduction of offspring that have different variations in genetic traits.
Which of the following is the sequence in which these steps take place?

Natural selection is the process by which organisms that are better suited to their environment are able to survive and produce more offspring. As a result of natural selection, the proportion of organisms within a species that have favorable adaptations to a given environment will increase with each generation.
Organisms (within populations) have differences in appearance and behavior on an individual basis. These differences, or variations, can include characteristics such as body shape or size, skin or hair color, physical markings or structures, or behaviors such as methods of obtaining food.
Organisms, within a species, that possess physical and behavioral traits that allow them to be more successful in obtaining resources will be more likely to survive and reproduce.
When organisms are faced with environmental changes, we often see a shift in what is considered a "favorable" trait within the species. This then has an effect on the overall population of organisms in terms of their physical and behavioral characteristics.
These "best adapted" traits will be passed onto the next generations given that individuals with these traits will be more likely to survive and continue reproducing.
