Which process results in the evolution of organisms best adapted to their environment?

• A. Gene Flow
• B. Natural Selection
• C. Genetic Drift
• D. Speciation

Answer: (B)

The process that results in the evolution of organisms best adapted to their environment is natural selection. This concept, originally proposed by Charles Darwin, is based on the premise that within a given population, individuals possess variations in their traits. Some of these variations confer advantages in survival and reproduction relative to others in a specific environment. When individuals with advantageous traits reproduce, they pass those traits to the next generation, gradually leading to a population that is better suited to its environment. This process enhances adaptive traits over generations, ultimately shaping the species' evolution in a way that maximizes their fitness in a changing or specific context. Natural selection is an ongoing process and is fundamental to the theory of evolution, influencing the traits that get passed on from one generation to the next. Other processes, such as gene flow and genetic drift, also contribute to evolution but do so in different ways. Gene flow involves the transfer of genetic material between populations, which can introduce new genetic variations but does not specifically favor the adaptation to an environment. Genetic drift refers to random changes in allele frequencies in a population, especially in small populations, but it does not lead to adaptations based on environmental pressures. Speciation is the process by which new species arise and is often a result of prolonged natural
