Evolution is a continuous process shaped by natural selection and genetic variation from "summary" of Seeds of Science by Mark Lynas
Evolution is a process that has been continuously occurring throughout life's history on Earth. It is a natural phenomenon that is shaped by two key factors: natural selection and genetic variation. Natural selection refers to the process by which certain traits or characteristics that increase an organism's chances of survival and reproduction are passed on to future generations. Genetic variation, on the other hand, is the diversity of genes within a population. This variation is the result of mutations, which are random changes in an organism's DNA. Mutations can lead to new traits or characteristics that may provide an advantage in certain environments. Over time, these advantageous traits become more common in a population through natural selection. The combination of natural selection and genetic variation results in the evolution of species over time. As the environment changes, organisms must adapt in order to s...
