evolutionary history
Evolutionary history traces how living organisms have changed over millions of years through processes like natural selection, where beneficial traits become more common. This gradual change results in the diverse species we see today, all sharing common ancestors if we look far enough back in time. Fossils, genetics, and comparative anatomy help scientists understand these links, revealing an ongoing story of adaptation and survival. It's a foundational concept that explains the interconnectedness of all life on Earth and how species evolve in response to their environments over generations.
