These wolves had to emigrate due to lack of food, they traveled to find a new home.
One day, a river grew between them. This can also be seems an isolating mechanism.
An isolating mechanism is any property of two species that stops them from interbreeding.
They decided to go their separate ways. Over time this caused variation.
Variation is any difference between cells, individual organisms, or groups of organisms of any species.
Selection is the preferential survival and reproduction or preferential elimination of individuals with certain genotypes, by means of natural or artificial controlling factors.
The wolves who were separated ended up in a completely new environment causing selection to occur.
This means that over time, some of the wolves developed gills and webbed feet to survive in their new location.
Since their new traits were so useful, it ranged to being a trait in more and more of the wolves over time. In other words, it was became an inherited trait that every wolf had.
Inheritance is the transmission of traits or information from one generation of individuals or cells to the next.
This resulted in overall Speciation.
Speciation is the evolutionary process by which populations evolve to become distinct species.
