Evolution shapes the diversity of life from "summary" of The Biology Book by DK
Evolution is the force that drives the diversity of life on Earth. It is the process through which new species emerge, existing species change, and life adapts to its environment. Evolution occurs through the mechanism of natural selection, where individuals with favorable traits are more likely to survive and reproduce, passing those traits on to their offspring. Over time, these small changes accumulate, leading to the formation of new species. One of the key aspects of evolution is genetic variation. Genetic variation is the raw material upon which natural selection acts. It is generated through processes such as mutation, gene flow, and genetic recombination. This variation allows populations to adapt to changing environmenta...
