Evolution and Natural Selection
Since Darwin's groundbreaking observations in the Galapagos Islands, evolutionary theory has revolutionized scientific understanding of species development and biodiversity. Through evolutionary mechanisms, organisms adapt to environmental pressures over successive generations, leading to the emergence of new traits and species.
Natural selection serves as the primary driver of evolution, where organisms with advantageous characteristics survive and reproduce more successfully than those without these traits. This process occurs through genetic variation, inheritance, competition for resources, and differential survival rates. Environmental factors, such as climate changes, predation, and resource availability, influence which traits become more prevalent in populations over time. Modern evolutionary biology integrates genetics, molecular biology, and paleontology to explain both gradual and rapid changes in species across geological timescales.
