The Evolutionary Insights of Charles Darwin and His Journey Through Natural Selection

Charles Darwin, born in 1809, is renowned for his theory of evolution and natural selection. His studies on tortoises and finches led to the understanding that species adapt over time. Modern scientists have expanded on Darwin's work, using DNA analysis to explore human evolution and brain development, highlighting the impact of genetic mutations.
