Question

1. what is the difference between natural selection and artificial selection?

Explanation:

Natural selection is a process where environmental pressures (like predation, resource availability) drive the survival and reproduction of organisms with advantageous traits, leading to evolutionary change over generations (e.g., peppered moths adapting to pollution - dark moths surviving better in polluted areas). Artificial selection is when humans deliberately choose organisms with desired traits (e.g., specific fur color in dogs, high - yield crops) to breed, guiding the evolution of the population towards those traits. The key difference is the agent of selection: nature (environmental factors) for natural selection, and humans for artificial selection.

Answer:

• Natural Selection: Driven by environmental factors (e.g., climate, predators, resource availability). Organisms with traits that increase survival and reproductive success in their natural environment are more likely to pass on their genes. Over time, this leads to adaptations that enhance fitness in that environment (e.g., camouflage in prey species, drought - resistant plant traits in arid regions).
• Artificial Selection: Driven by human choice. Humans select organisms with desirable traits (e.g., large fruit size in plants, docile behavior in animals) and breed them. The goal is to produce offspring with those desired traits, often for human use or aesthetic purposes (e.g., breeding different dog breeds, selecting for high - milk - producing cows). The main difference is the selector: nature (environmental pressures) for natural selection, and humans for artificial selection.
