Answer:

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 may result in the loss of some alleles (including beneficial ones) and the fixation.

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).

Why can’t your body heal an amputation, such as the loss of a finger, the same way it can heal a cut?

Answer:

For a limb to regenerate, you need bone, muscle, blood vessels and nerves. There are adult stem cells, a kind of undifferentiated cell that can become specialized, that regenerate muscle, but they don't seem to activate.
