Introduction

Learning objectives

  • Science: Variation between species and between individuals of the same species means some organisms compete more successfully, which can drive natural selection.
  • Changes in the environment may leave individuals within a species, and some entire species, less well adapted to compete successfully and reproduce.

Students’ outcomes

  • To be able to explain the process and effect of natural selection on the finches of Daphne Major.
