Show transcript
Natural selection can cause the common characteristics of a species to change (evolve) over generations.
Scientists explain evolution using the theory of evolution by natural selection.
A scientific theory is a general explanation, developed from evidence, that explains many different examples.
Evolution is not planned in advance; new advantageous features appear randomly and are maintained by natural selection.
Changes in the features of an individual within its lifetime are not evolution.
