About this worksheet
Natural selection is the process in which organisms better suited to their environment survive and reproduce, passing on their helpful traits. This worksheet builds the vocabulary – variation, trait, adaptation, fitness, species, and environment – and connects natural selection to evolution.
The reference box and Section A are on page 1. The reference box defines eight terms about natural selection. Section A has eight clue-matching items. Section B on page 2 has four short-response questions, including giving an example of an adaptation.
Page 3 is a complete answer key with the term for each clue and a sample answer for every short-response question. The worksheet pairs well with the Animal Adaptations and Inherited and Learned Traits worksheets.
