Artificial selection is the human practice of selectively breeding plants or animals for specific traits. Unlike natural selection, where environmental factors drive evolution, humans intentionally choose which traits to pass on in artificial selection.

Yes, evolution can be observed in real time, particularly in species with short life cycles, such as bacteria. For example, the development of antibiotic resistance in bacteria is an example of rapid evolutionary change.

Environmental changes can drive evolution by creating new challenges for survival. Organisms with traits that help them adapt to these changes are more likely to survive, while those that cannot adapt may become extinct.

Homologous structures are body parts that share a common evolutionary origin but may serve different functions, such as the forelimbs of humans and bats. Analogous structures, on the other hand, serve similar functions but do not share a common ancestry, such as the wings of birds and insects.

Yes, evolution is an ongoing process. Populations continue to adapt to changing environments, and genetic mutations continue to introduce new variations.
