Natural selection is the result of natural factors, which favour certain variations. Artificial selection is the deliberate selection of certain traits (by humans), for example a Poodle is the result of artificial selection.
Natural selection occurs when a particular feature gives an organism a survival or mating advantage-- so for example, giraffes with longer necks were better able to feed themselves than those with shorter necks. Over time longer necked giraffes were better able to survive and breed. So longer necks were selected for naturallly.

Artificial selection is when humankind chooses certain traits and breeds organisms for that trait. Example-- the domestic dog. The original organism was the wolf. Humans chose certain traits, such as size or temprement and bred together those with the desired trait(s). Hence the various breeds we have today.
Natural selection is largely determined by environmental factors, where nature chooses organisms with the best traits for survival.

  • Tigers developed stripes so they could sneak up on their prey easier. The stripy tigers caught more prey, became healthier than tigers that have more trouble catching prey, and produced more stripy offspring.
  • For example, long-necked giraffes are chosen by naturebecause they're tall and can reach higher leaves, while shorter-necked giraffes can't reach as high and might starve to death.

Artificial selection is controlled by humans, where a person chooses which traits of the organism that he wants it to have.

  • Pug dogs have pug faces because people bred male dogs with pug-ish faces and female dogs with pug-ish faces to produce offspring with totally pug faces.
  • People choose the fat cows to breed more fat cows because they've more meat. This decreases the eventual number of skinnier cows.

What is the difference between natural selection and artificial selection?

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).

What is the difference between artificial and natural selection?

Natural selection is when genes are passed on naturally through animal intercourse. Artificial selection is when they are passed on unnaturally through human intervention examples would be breeding and artificial insemination.

Explain the difference between artificial and natural selection?

Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.


Is artificial selection part of natural selection?

NO. Both artificial and natural selection are forms of Evolution in general. Both cause variation by selection within a particular population. The only difference is who is doing the selection, humans or nature.


Explain the difference between natural selection and artificial selection?

natural selection is basically survival of the fittest (antelope v. lion), arteficial selection is the basic human breeding and selection of species (carrots, cows, chickens, lettuce)


What role does nature play in artifcial selcetion?

Nature plays no direct role in artificial selection. That is the difference between artificial selection and natural selection. Nature does play some indirect roles in artificial selection. One indirect role is in providing the organisms with which one beings the artificial selection. Another is in influencing the choices of the organism performing the artificial selection.


Artificial selection is similar to natural selection in that both processes?

The similarity between artificial and natural selection is that they are both weeding out unfavorable traits for favorable traits to be well equipped for survival.


How are artificial selection and natural selection the same?
