Hint: Organs that differ in origin but are similar in function are called analogous organs. Examples of such traits are the wings of insects, bats, and birds, which evolved independently of each line after being separated from their wingless ancestors. The insect's wings begin on the inner or outer surface of the insect's body. Bird feathers come from the forelimbs, while the wings of bats come from the forelimbs and abdominal skin.
Complete answer: Evolution is the change in the genetic characteristics of a biological population over the next several generations. These traits are expressions of genes that are passed from parent to offspring during reproduction. There are different traits in a population due to mutations, genetic recombination, and other causes of genetic variation.
Convergent evolution- Convergent evolution is the process by which disparate or distant organisms develop similar body shapes, colors, organs, and adaptations. Natural selection can lead to evolutionary convergence in a wide variety of situations. Examples of such traits are the wings of insects, bats, and birds, which evolved independently of each line after being separated from their wingless ancestors. The insect's wings begin on the inner or outer surface of the insect's body. Bird feathers come from the forelimbs, while the wings of bats come from the forelimbs and abdominal skin.
Divergent evolution- Divergent evolution is defined as the differences between closely related populations within a species, leading to speciation. Differential development usually occurs when two populations are separated by a geographic barrier.
Adaptation evolution- Natural selection only affects the genetic characteristics of a population. By natural selection beneficial alleles are selected, their frequency increases in a population, making decisions about harmful alleles, and their frequency decreases (a process known as adaptive evolution).
Parallel evolution- Parallel evolution is the development of similar traits in separate species with similar initial characteristics in response to similar evolutionary pressures,
So, the correct answer is “Option A”.
Note:
When the characteristics of two species are similar, evolution is defined as parallel if the ancestors are similar, and convergence otherwise. Some scientists argue that there is a continuum between parallel and convergent evolution, while others argue that there is some overlap, but there are still significant differences between the two.
As long as evolution proceeds without convergence, phylogenetic and hereditary reconstruction will continue. However, convergent models can occur at a higher level of phylogenetic reconstruction, and sometimes researchers are clearly looking for them. How one can infer that convergence has evolved depends on whether model or process convergence is expected. Model-driven convergence is a broader term when it comes to the independent development of models in which two or more lines have similar characteristics. The convergence process occurs when convergence occurs under a similar force of natural selection.
