Charles Darwin (theory of evolution)

Charles Darwin's theory of evolution explains how species change over time through a process called natural selection. He proposed that individuals with traits better suited to their environment are more likely to survive and reproduce. Over generations, these advantageous traits become more common in the population. This gradual change can lead to the emergence of new species. Darwin's work, particularly in his book "On the Origin of Species," revolutionized our understanding of biology by providing evidence that all living organisms share a common ancestry and have adapted to their environments through evolutionary processes.
