What is the process by which organisms adapt to their environment over many generations?
Answer
Natural selection
Natural selection is the mechanism of evolution proposed by Charles Darwin, where organisms with advantageous traits for their environment are more likely to survive and reproduce, passing those traits to offspring. Over many generations, beneficial traits become more common in a population while disadvantageous traits diminish. Natural selection acts on genetic variation within populations, favoring traits that enhance reproductive success. This non-random process explains the tremendous diversity of life on Earth and how species adapt to environmental challenges over evolutionary time.
