The of evolution explains how species change over time through the process of . This theory, first proposed by , suggests that individuals with traits better suited to their environment are more likely to survive and reproduce. Over many generations, these advantageous traits become more common in the population, leading to the gradual transformation of species.
Genetic variations arise from mutations, which can be caused by various factors including and . These variations are crucial for the process of evolution, as they provide the raw material upon which natural selection can act. When a mutation results in a favorable trait, it may enhance an organism's fitness, increasing its chances of survival and reproduction within its environment.
The concept of adaptation is central to understanding how organisms evolve. Adaptations are traits that have evolved through natural selection, making an organism better suited to its . There are various types of adaptations, including , behavioral, and physiological changes that aid in improving survival rates. Over time, these adaptations can significantly affect the diversity and complexity of life forms on Earth.
