Natural selection.
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.

Demographic transition
This term is known as natural selection. It is a fundamental mechanism of evolution, where organisms with advantageous traits are more likely to survive, reproduce, and pass on those traits to future generations.
Demographic transition
Demographic transition
A sampling variability is the tendency of the same statistic computed from a number of random samples drawn from the same population to differ.
Demographic transition
Natural selection tends to decrease genetic variation within a population by favoring certain traits that are advantageous for survival and reproduction.
Aversion is the antonym for the word tendency.
