Differences between individuals that are caused by the environment are known as environmental variation.

Differences between individuals that are caused by the genetic material they inherit are known as genetic variation.

Heritable traits are features that can be passed on from a parent to their offspring via instructions stored in genetic material (DNA).

Heritable variation

Science

Pupils will learn that the fossil record provides evidence of evolution from common ancestors through transitional species to modern species, and that the theory of evolution by natural selection can be used to explain phenotypic changes in populations of species over generations.

Pupils learned that variation (differences in the features of individuals of the same species) can be caused by environmental and genetic factors.
