Answer:
Population Bottleneck
Explanation:
Population Bottleneck refers to the evolutionary events that result in drastic reduction in population size of a species. It may be caused by any environmental factors such as natural disasters or man activities such as hunting. Population bottleneck reduces the population size to the level of its extinction.
However, species conservation programs could have resulted in increased in the population size back. Hence, the population experienced "population bottleneck".
Answer:
Population Bottleneck
Explanation:
The bottleneck effect occurs when changes occur in the environment, so as to dramatically reduce the size of a population. The name “bottleneck effect” stems from the fact that only part of the population resists a certain pressure from the environment. It would be like a bottle full of marbles, with only a few going through the neck and some not. An example of this occurs when a small population of an almost extinct species of animals has survived and reproduced.
