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 daschunds?
Responses
A Natural selection leads to evolution.Natural selection leads to evolution.
B There is very little genetic variation in all living species.There is very little genetic variation in all living species.
C There is over-reproduction in all living species to ensure their survival.There is over-reproduction in all living species to ensure their survival.
D Competition favors the most fit organism
D Competition favors the most fit organism.
D Competition favors the most fit organism
The correct answer is D: Competition favors the most fit organism.
The theory of evolution by natural selection states that in any population, there is variation in traits, and these traits can be inherited. In the case of dog breeds, there is a wide range of genetic variation that has been selectively bred by humans over many generations.
Natural selection occurs when individuals with certain advantageous traits have a greater chance of surviving and reproducing in their specific environment. This leads to the passing on of those advantageous traits to future generations.
In the case of wild wolves, their traits are shaped by the process of natural selection. Wolves have evolved traits that make them well-suited for survival in their specific environments, such as their sharp teeth, powerful muscles, and social hunting behavior.
On the other hand, dachshunds have been selectively bred for specific traits, such as their long bodies and short legs. These traits were not naturally selected but rather intentionally bred by humans for their unique appearance or specific purpose, such as hunting badgers.
In the wild, the traits of dachshunds would not provide them with an advantage for survival or reproduction. Their long bodies and short legs would likely hinder them from effectively hunting or escaping predators. As a result, dachshunds would not have been selected for in the process of natural selection.
Therefore, the lack of wild wolves resembling dachshunds can be explained by the principle of natural selection favoring traits that are best suited for survival and reproduction in a particular environment.
