Natural selection occurs when ecological pressures "select" for one trait over another. For example, if it is cold, an animal with a heavier coat will survive longer than one with a thin coat. The one with the heavy coat will have more offspring and that gene will be more frequent in the gene pool than the gene for a thin coat.
Artifical selection occurs when a desirable trait is selected and an undesirable one is not. For example, a long flowing coat on a dog may be more desirable to a breeder than a short, ragged coat. The breeder selects the genes.

Compare and contrast natural selection and artificial selection?
Natural selection is when contemporary species rose from ancestors that survived due to their physical characteristics in their habitats. A well-known example is the Galapagos Islands and how the animals on the islands adapted to their environments. Darwin convinced the biology world that diversity in organisms came from evolution (descent without modification). Artificial selection is when humans intentionally breed animals for certain traits. Unlike natural selection, where only the fittest survive, artificial selection is for human's likings. Many crops that are grown are part of artificial selection.
Is nizam sagar a natural lake or an artificial lake?
It is an artificial lake.
What is the relationship between adaptation and natural section?
Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

When Charles Mendel developed the theory of natural selection in the 1800s he did not include a genetic explanation. True of false?
False. Charles Darwin developed the theory of natural selection in the 19th century, but he did not have a genetic explanation for inheritance as it was not understood at the time. The principles of genetics were later established by Gregor Mendel, whose work on inheritance patterns was published around the same time but remained largely unrecognized until the early 20th century. Thus, while Darwin's theory of natural selection focused on variation and adaptation, it did not include a genetic framework.
What are the release dates for Natural Selection - 2004?
Natural Selection - 2004 was released on: USA: 15 December 2004 (Cinema Slam Film Festival)
What principles includes variation and competition?
Natural selection.
What is one factor that affects natural selection and artificial selection?
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.
What is the difference between the processes of natural selection and artificial selection?
the difference between the 2 r that natural is the best looking or tasting and artificial is fake

What role does the environment play on natural selection?
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.
What is the difference between artificial selection and natural selections?
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).
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
What drives the rate of diversity change?
Natural selection, Evolution, Artificial selection, disasters
Artificial selection example?
Think GMO crops. Not natural selection, we selected them artificially
