Homework Answers
The correct option is e) both a and b.
Natural selection favors phenotype which are better adapted to the environment.
It favors trait having higher chances of survival and reproduction in the given environment.
It is not a random process but mutation is.
It does not lead to perfectly optimal organisms but organisms having traits better suited in the environment.

Evolution by Natural Selection can be described as: A) individuals with traits that increase survival will become more common, even if they don't reproduce B) individuals with genes that allow them to sacrifice themselves for the species are the more evolved C) Species evolve as a whole with all individuals within the population evolving at the same time D) Individuals with traits that increase survival and produce more offspring as a result, their genes become more common in the population
