Example of how natural selection occurs?

Answer 1

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.

Answer 2

When a species contains few mutations

Natural selection has been, is, and will always be an ongoing process. A member of a species is born with a major or minor modification.

• If the change makes it easier to survive in its environment, it will flourish, procreate and spread the mutation to its progeny.
• If the change makes it more difficult to survive, it is more likely to not live long enough to procreate and spread its genetic change.

Answer 3

Natural selection would occur in evolution. Only those with the best traits will be able to continue on the species.

Answer 4

a population of salmon with different skin colors that attract mates

Answer 5

When there are to many of the same species, the animals with the better adaptations survive.

Answer 6

No scenarios, but......

What results from natural selection in the long run is adaptive change and this can, under the right environmental conditions, lead to speciation.

Which example best illustrates a condition necessary for natural selection to occur?
