Theory of evolution (Darwin)

The theory of evolution by Charles Darwin explains how living organisms change over time. It states that individuals within a species vary naturally, and some variations give them advantages in survival and reproduction. These advantageous traits are more likely to be passed on to future generations. Over many generations, this process leads to gradual changes and the development of new species. Evolution occurs through natural selection, where the environment "selects" the traits that help organisms thrive. This process explains the diversity of life on Earth and how species have adapted to their environments over millions of years.
