4 postulates of natural selection
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species. Select from these resources to teach your classroom about this subfield of evolutionary biology. a. Natural selection can be used by farmers to generate organisms with desirable traits. b. Natural selection occurs in opposition to evolution. c.

(3) Fitness is based on characteristics which are inherited. (4) Adaptive ability is inherited.natural selection acts on traits, mutations for advantageous traits are more likely to be passed on to the next generation, and natural selection favors some mutations.
