Natural selection is when 'nature chooses' the organism with the favourable characteristics to survive. E.G. Giraffe's Long-necked giraffes are 'chosen by nature' because they have the favourable characteristic of being tall, which allows them to reach higher branches in higher trees. Whilst shorter-necked giraffes cant reach this food source and as the shorter trees run out of vegetation, the shorter-necked giraffes will end up dead.
Artificial selection is when 'man-chooses' the organism that he wants because of their favorable characteristics,
E.G Choosing the 'fat' cows to breed to produce more fat cows because they have more meat in them. This will in-turn affect the numbers of the 'skinner' cows with undesirable characteristics.
Artificial selection is where man selects organisms with useful characteristics to him whereas natural selection is the process whereby nature selects the fittest organisms.
A2. Some social insects such as ants employ aphids to grow fungi, it follows that the ants also have a part to play in Artificial Selection, in both the aphids and the fungi. So it is not just man.
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.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
The difference is the same as in other contexts.* "Artificial" means that something was created by humans. * "Natural" means that it was NOT created by humans.
Natural selection and artificial selection are not opposites; rather, they are both mechanisms of selective breeding. Natural selection occurs in nature with environmental factors determining which traits are passed on to offspring, while artificial selection is guided by human intervention to produce specific desired traits in organisms. Both processes involve the differential survival and reproduction of individuals based on their inherited characteristics.
Think GMO crops. Not natural selection, we selected them artificially
the difference between the 2 r that natural is the best looking or tasting and artificial is fake
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).
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.
Technically, yes, but only because they are using virtually the same processes, the only real difference between the two, is like the difference between choosing your own mate and having someone choose your mate for you.
Natural selection is more efficient ad more precise.
Natural selection - is allowing the species to breed at their own convenience - with whichever member of the opposite sex they choose. Artificial selection is human intervention in that natural process - allowing breeders to choose the best genes for the species.
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.
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
The difference is the same as in other contexts.* "Artificial" means that something was created by humans. * "Natural" means that it was NOT created by humans.
natural has no added chemicals, colours etc.. artificial has, like sweetners, salts, colours etc..
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.
