Detailed explanation-1: -The fossils of an extinct amphibian can be found in South America, Africa, and Australia. Which of the following statements best describes this occurrence? These continents were once next to one another before the process of continental drift separated them.

Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-3: -Explanation: In selective breeding, individuals possessing desired traits are bred in the hope that they will pass on the alleles for the desired trait to their offspring.

Detailed explanation-4: -Natural selection is driven by environmental factors that limit survival and reproduction, such as harsh environments or competition for mates. Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.

Detailed explanation-5: -Artificial selection, also called “selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
