A species of a large brown bear lived in Siberia about a million years ago. Over time, the northern population became white-colored and acquired heavier fur as it blended into the snowy landscape. The southern population acquired lighter, darker-colored fur as it adapted to forest ecosystems. Eventually, they could no longer reproduce with each other. Which of these terms describes this transition?
a. transmofrification
b. coincidence
c. providence
d. lost in translation
e. speciation

e. speciation

Explanation:

The definition of speciation is:  the evolutionary process by which populations evolve to become distinct species.

In this scenario, the bears that were once of the same species evolved in order to adapt to their environment. Once they evolved, they could no longer produce with each other, as they are now different species.
