Darwin's theory of evolution

Darwin's theory of evolution posits that species change over time through a process called natural selection. Individuals with traits that better suit their environment are more likely to survive and reproduce. Over generations, these advantageous traits become more common in the population, leading to gradual changes in the species. This process explains the diversity of life on Earth and how complex organisms evolved from simpler ancestors. Darwin's insights challenged traditional views by suggesting that species are not fixed but constantly adapting to their surroundings.
