Directional Selection
genetic drift
Many polygenic traits are represented by a bell cure because they are controlled by many genes and result in gradations where each gene has an effect.
It is called "natural selection", also known popularly as "survival of the fittest". This mechanism suggests that organisms will flourish if they are compatible with their environment (light, food, water, predators, weather), and will die and cease reproduction if they are not.

A selection of multiple cells is oftenreferredto as a range.
It's usually called stabilizing selection.
This is designated as the organisms fitness.

Yes, that is more or less what we call natural selection. Although we usually speak of the adaptation of entire populations, not individuals - and a population has adapted if its average fitness (reproductive rates) has reached some optimal value, which means that natural selection has already acted. So it would be more accurate to say that it is called natural selection when the fitter members of a population reproduce to a greater degree than the less fit members.

Yes, it is called evolution. It happens because individuals in the species die and new ones are born. The new individuals are slightly different than the old individuals. Selection processes of many different types cause more individuals that are less well adapted to the selection criteria to die, resulting in shifts that result in the species being better adapted overall to those selection criteria.
Natural Selection is a process which individuals are better adapted to their enviorment are more likely to survive and reproduce. Say there are turtles barely hatching and there are hungry seagul waiting to be fed, the fastest ones will make it to the water safely while the slow ones are being eaten. so eventually all the turtles in the sea will become faster to get away from predators. hopefully that answered your question.
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
