The Genetic Basis of Evolution

The genetic basis of evolution stems from changes in the DNA of living organisms. These changes, or mutations, can occur naturally and may affect traits that help or hinder an organism's survival and reproduction. When organisms reproduce, they pass on their genes to their offspring. Over time, beneficial traits become more common in a population, leading to evolution. This process is driven by natural selection, where individuals with advantageous traits are more likely to thrive and reproduce. Ultimately, the diversity of life we see today is the result of millions of years of genetic variation and selection processes.
