Speciation! Speciation occurs when a single species becomes two or more separate populations by a geographical barrier. This changes each population’s environment which forces them to adapt. Eventually these populations will become so different from each other that they will not be able to interbreed populations and create fertile offspring. This is what makes them different species, but they still share a common ancestor.

According to the theory of natural selection, adaptive traits that enable organisms to survive in an environment are selected by the forces of natural selection.
<u>When a particular trait is not needed for survival in an environment, the trait gradually degenerates within the population as natural selection ignores the existence of such trait. The degenerated trait is inherited by the subsequent generations of the population.</u>
The mechanism is also consistent with the law of use and disuse of organs by Jean Larmack.
The correct option is B.
I'm pretty sure its so the evidence isn't tampered with...
The factors that affect temperature or altitude latitude and distance from sea the height measured from sea level is called altitude when the latitude increases the distance from the Sun Also increases so the temperature gradually decreases
