Evolution is the process by which living organisms change over time in response to changes in their environment. It is driven by the mechanisms of variation, inheritance, and natural selection. Evolutionary changes can occur at various levels, including within a population, across different populations of the same species, and even over long periods of time leading to the emergence of new species.
Charles Darwin’s theory of evolution, often referred to as Darwinism or the theory of natural selection, is a scientific explanation for how evolution occurs. Darwin’s theory proposes that all species of organisms have descended from common ancestors through a process called descent with modification. According to Darwin, the driving force behind evolution is natural selection, which acts on heritable variations in a population.
Natural selection occurs when individuals with certain heritable traits are more likely to survive and reproduce than individuals with other traits. Over time, these advantageous traits become more common in the population because they are passed on to the next generation. This process leads to the adaptation of species to their environment, as individuals with traits that enhance their survival and reproduction are more likely to pass on their genes.
Darwin’s theory of evolution has provided a comprehensive explanation for the diversity of life on Earth and has been supported by extensive evidence from various fields of study, including paleontology, genetics, and comparative anatomy. It remains one of the fundamental concepts in biology and has had a profound impact on our understanding of the natural world.
