The human race nearly became extinct when the population dropped to just 1,280. Research suggests early humans were nearly wiped off the face of the Earth 900,000 years ago when the planet ...

The first such event took place 900,000 years ago, when a “ population bottleneck ” is theorized to have occurred, leading to suggestions that humanity may have almost become extinct.

The bottleneck, potentially caused by a period of global cooling, continued until 813,000 years ago, the study said. Then there was a population boom, possibly sparked by a warming climate and ...

(MENAFN) Evolutionary scientists have uncovered evidence that Indian elephants experienced a significant population bottleneck nearly 2,000 years ago, lasting for around 1,500 years.

A bottleneck, however, reduces the diversity of segments. Because of recombination events over time, the lengths of these segments gradually shorten (moving clockwise around clock).

Check out this cool paper in PLOS Genetics: In this first application of the approximate Bayesian computation approach using the serial coalescent, we demonstrated the estimation of historical ...

Monitoring temporal changes in genetic variation can provide estimates of effective population size (Ne) that are useful for detecting population bottlenecks. We used Monte Carlo computer simulations ...

We apply new analytical methods to understand the consequences of population bottlenecks for expected additive genetic variance. We analyze essentially all models for multilocus epistasis that have ...
