This text delves into the various mechanisms of natural selection, including directional, disruptive, and stabilizing selection. It provides insights into how these processes influence the evolution of species, with specific examples such as Darwin's finches. It also highlights how stabilizing selection can manifest in human traits, such as birth weight. By exploring these concepts, we gain a deeper understanding of the dynamics of evolution and the factors that contribute to biodiversity.
