2. Wolves have genes that give them a very powerful sense of smell much more
powerful than humans, this is an adaptation by natural selection. The wolves that
reproduced more offspring with a better sense of smell thereby increasing the
frequency of those genes in the population that survived longer. Give an example of
adaptations in other organisms that may have resulted from variations that were
favored by natural selection.

According to the evolutionary theory proposed by Darwin, natural selection is a mechanism that acts on heritable phenotypic variation among individuals within a population. Genetic variation can be considered as the primary source of heritable phenotypic variation. Those organisms that are better adapted for a particular environment will have more chances to survive and reproduce, thereby passing these heritable traits to the next generation. For example, during his work, Darwin observed that the shape and size of beaks in finch species from different islands in the Galapagos archipelago varied as a consequence, i.e., as an adaptation, to the availability of food resources present in each island.

An example of adaptations in other organisms that may have resulted from variations that were favored by natural selection. - The light-colored mice are an adaption favored by natural selection as they were able to live longer.

Adaptations are physical or behavioral traits that make an organism better suited to its environment. The inheritable variation comes from random mutations.

the example of such variations caused by natural selection are:

The Deer mouse adapted to the environment by developing a lighter color.
The light-colored mice were able to live longer.

Thus, The light-colored mice are an adaption favored by natural selection as they were able to live longer.
