experienced what is known as a "bottleneck event." In simple terms, the population of these species was reduced so much that the genetic diversity within the population had significantly decreased.

Chemical reactions are often interpreted using transition state theory (TST) where the transition barrier often forms a bottleneck between reagents and products. The detailed dynamics near a TS can be ...

Homo sapiens evolved through a series of significant genetic events. A population bottleneck approximately 900,000 years ago is thought to coincide with genomic rearrangements, the fusion of ...
