Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
Because they have the nutrients humans need to survive, if you stopped eating vegetables you'd get really weak.
This is False as they have actually had an increase in motorcyclists which have been killed and injured.
