Natural Selection Overview
Natural selection stands as one of the most fundamental concepts in the realm of evolutionary biology, shaping the diversity of life on our planet. Proposed by Charles Darwin in the mid-19th century, this process serves as the cornerstone of modern evolutionary theory. At its core, natural selection acts as a mechanism for the differential survival and reproduction of organisms based on their heritable traits. By favoring those traits that confer advantages in a given environment, natural selection drives the gradual adaptation of populations over successive generations. This essay will delve into the intricacies of natural selection, exploring its mechanisms, implications, and significance in understanding the complexity of life.
