What are the random and nonrandom factors that drive evolution?

Answer 1

Evolution is driven by both random and nonrandom factors. Random factors include genetic mutations and genetic drift, which introduce variability without regard to whether the changes are beneficial or harmful. Nonrandom factors encompass natural selection, where organisms with advantageous traits are more likely to survive and reproduce, leading to the propagation of those traits in the population. Together, these factors shape the genetic makeup of populations over time, influencing the course of evolutionary change.
