Detailed explanation-1: -Without evolution, every living thing would get extinct. Q: How does evolution happen? Evolution happens when environmental conditions change, and species need to adapt to the new conditions slowly to survive, otherwise, they will die out.

Detailed explanation-2: -Biological evolution explains both the unity and the diversity of species and pro-vides a unifying principle for the history and diversity of life on Earth. Biological evolution is supported by extensive scientific evidence ranging from the fossil record to genetic relationships among species.

Detailed explanation-3: -Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms’ genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.

Detailed explanation-4: -What happens to a population when biological evolution takes place? A change takes place in the genetic traits passed from one generation of the population to the next.
