There are many different types of dog breeds, despite the fact that they are all one species, Canis familiaris and all have a common ancestor, the wolf, Canis lupus. Many breeds, such as the Alaskan malamute and the Siberian husky look remarkably like wolves and even retain some of their habits. Other breeds like the daschund above, do not strongly resemble wolves.

What part of the theory of evolution by natural selection would explain why there are no wild wolves that resemble dachshunds?

A) Natural selection leads to evolution.
B) There is very little genetic variation in all living species.
C) There is over-reproduction in all living species to ensure their survival.
D) Competition favors the most fit organism.

D) Competition favors the fittest organisms.
This is correct because, in different parts of the world, different organisms need different things to survive, which means if Wolves in Alaska need warm coats to survive, but animals in some parts of America don't, each animal that is the fittest to live in those conditions will survive, while the others with unfavorable genes will not.
