In more technical terms, biological evolution is defined as change in the gene pool of a population, measurable as changes in allele frequencies in a population over time In the earlier reading, we touched on evolution by natural selection and evolution by mutation

The evolution of species is not a ladder but a vast, branching tree—one with roots deep in ancient seas and branches reaching toward every corner of the Earth From microbes to mammals, from dinosaurs to dolphins, from cyanobacteria to chimpanzees, the story of evolution is the story of life adapting, surviving, and transforming in response
