Lets say you have two bunnies. One has a long tail, the other has short tail. The one with the long tail died because a predator was able to catch onto the long tail and eat it. Therefore, the long tailed bunny can't pass on the characteristic of a long tail and that trait is no longer seen in bunnies. However, the bunny with the short tail isn't caught by predators as easily, and as a result, passes on the trait of a short tail to its offspring. After a long amount of time, no bunnies will have long tails because all the bunnies with long tails were killed out, and as a result, can't pass on the characteristic of a long tail. Bunnies then evolve to always have short tails.
when there is competition
To begin with, a theory can not prove or disprove anything until it is proven itself.
Adaptation does not allow for natural selection: natural selection causes adaptation.
natural selection occurs when animals need it
Natural selection is the means by which living things are selected to reproduce. It is called natural because it is what happens in what is considered ordinary living conditions. It works by allowing only those creature capable of surviving getting to reproduce. If a creature is incapable of living/surviving in the environment that it finds itself in then it doesn't reproduce and becomes extinct.
No, natural selection is the mechanism that drivesevolution.
natural selection occurs due to natural phenomena (e.g. changes in diet or predators).artificial selection occurs due to human generated phenomena (e.g. breeding or domestication).
natural selection
natural selection
It is an example of Natural Selection, Modern Theories of Evolution.
False, dog breeding would be an example of Artificial Selection.
False, dog breeding would be an example of Artificial Selection.
no, at the individual level
All modern lifeforms are examples of natural selection, since they are all the result of it.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
Think GMO crops. Not natural selection, we selected them artificially
is dog breeding an example of natural selection
