A wave traveling to the right on a stretched string is shown below. The direction of the instantaneous velocity of the point P on the string is:
Uniformitarianism
The principle suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present, and that this consistency accounts for all geological changes.
Allopatric Speciation
Speciation pattern in which a physical barrier arises and separates populations, ending gene flow between them.
Geographic Isolation
A form of reproductive isolation in which two populations are separated by physical barriers, leading to the development of distinct species.
Rapid Evolutionary Change
A process where species undergo significant alterations in their genetic makeup over relatively short geological periods, often in response to dramatic environmental shifts.
