Watch this video about natural selection plate tectonics. The movement of the plates can contribute to the natural selection of organisms. What is another natural process that contribute to evolution of a species Juneau? How does process affect evolution?

Bottleneck effect

Explanation:

The bottleneck effect is when a natural disaster happens, like an earthquake, hurricane, etc. and the population narrows tremendously. This only allows the surviving traits to be passed on and continue with evolution.

A natural disaster, such as an earthquake or a volcanic eruption, could affect the evolution of a species’ genome. These disasters could kill a large number of organisms at once, decreasing the genetic variation in the gene pool. In some cases, large populations may become separated, which can lead to several smaller populations evolving in different ways.
