In natural selection, those variations in the genotype that increase an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous ones.

Natural selection leads to adaptive evolution. An adaptation is a trait that an organism has that increases its chance of surviving and reproducing in its specific environment. An adaptation is.

Natural Selection Is Not Evolution! The supposed vehicles of evolution are mutations, natural selection, and other mechanisms that—when combined with that pixie dust of time—allegedly led to the development of all life forms present today.

In this resource, students focus on the role of natural selection in evolution, by considering the extent to which the winged fruits from a tree are adapted for successful dispersal. A great activity for a STEM science club, or as a a backup activity for a gardening club when it rains!

Futuyma: Natural selection is the process by which species adapt to their environment. Natural selection leads to evolutionary change when individuals with certain characteristics have a greater survival or reproductive rate than other individuals in a population and pass on these inheritable genetic characteristics to their offspring.

Natural selection is the cornerstone of Darwin’s theory of evolution; adaptations are the traits that allow organisms to survive the selection process.

Recent studies suggest that natural selection and adaptation may play a more significant role in the early stages of divergence and the evolution of reproductive isolation than previously thought.

In the 1920s and 1930s the so-called modern synthesis connected natural selection and population genetics, based on Mendelian inheritance, into a unified theory that applied generally to any branch of biology. The modern synthesis explained patterns observed across species in populations, through fossil transitions in palaeontology, and complex cellular mechanisms in developmental biology.
