Natural selection takes place when individuals with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Over time, this process leads to the accumulation of beneficial traits in a population and the adaptation of species to their environment. Random genetic mutations provide the variation on which natural selection acts.
Genetic change is necessary for natural selection to take place
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
Yes, natural selection occurs without human control. It is a process by which individuals with favorable traits are more likely to survive and reproduce, passing those advantageous traits to their offspring. This process shapes the evolution of populations over time based on the environment and genetic variability.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
