(From Wikipedia, the free Encyclopedia)
A bottleneck is literally the neck of a glass or pottery bottle. An hourglass has a bottleneck at its mid-point whose diameter governs the time that granular contents of a given mass will take to pass through.Metaphorically a bottleneck is a section of a route with a carrying capacity substantially below that characterising other sections of the same route.
This is often a narrow part of a road, perhaps also with a smaller number of lanes, or a reduction of the number of tracks of a railway line.
It may be due to a narrow bridge or tunnel, a deep cutting or narrow embankment, or work in progress on part of the road or railway.
More generally, a bottleneck is one process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain.

(From Wikipedia, the free Encyclopedia)
In evolution theory, a population bottleneck (or genetic bottleneck) is an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing, and the population is reduced by 50% or more, often by several orders of magnitude. A graph of this change resembles the neck of a bottle, from wide to narrow; hence the name.
In evolutionary theory, population bottlenecks are thought to accelerate the processes of natural selection and genetic drift.
Humans today are a legacy of a population bottleneck which occurred 70,000 years ago. This has had the result of limiting the overall level of genetic diversity in the human species, possibly by a large amount.
