Which of the following best describes the difference between selective breeding and natural selection?
A.
Selective breeding is the process of creating entirely new species, while natural selection modifies currently living species.
B.
Selective breeding is performed by humans to achieve desired traits, while natural selection occurs without human involvement.
C.
Selective breeding is performed by humans to change a trait in a currently living species, while natural selection is performed to change future offspring.
D.
Selective breeding is a type of breeding that organisms in the wild carry out, while natural selection is a type of breeding that domestic organisms carry out.
B. Selective breeding is performed by humans to achieve desired traits, while natural selection occurs without human involvement.

The best answer would be B. Selective breeding is performed by humans to achieve desired traits, while natural selection occurs without human involvement.
The correct answer is B. Selective breeding is performed by humans to achieve desired traits, while natural selection occurs without human involvement.
To arrive at this answer, let's break down the differences between selective breeding and natural selection:
Selective breeding is a process where humans deliberately choose specific individuals within a species to breed together in order to produce offspring with desired traits. This can be done to enhance certain characteristics, such as increasing crop yield, improving livestock for agricultural purposes, or breeding pets with specific physical or behavioral traits. Selective breeding is a conscious and directed process carried out by humans in order to achieve specific goals.
On the other hand, natural selection is a process that occurs in nature without any human interference. It is a mechanism by which organisms with traits that are advantageous for their environment are more likely to survive and reproduce, passing on those advantageous traits to future generations. Natural selection is driven by environmental factors, such as competition for resources, predation, or changes in habitat. It acts on the variability already present within a population and selects for traits that increase an organism's chances of survival and reproductive success.
Based on these explanations, option B is the best answer. It accurately describes that selective breeding is performed by humans to achieve desired traits, while natural selection occurs without human involvement.
