Practice: Evolution Vocabulary – Study Guide & Revision Notes
vestigial structures - correct answer ✔✔The wings of flightless birds, like the ostrich, are an
example of this
biochemistry - correct answer ✔✔study of nucleic acids
gene flow - correct answer ✔✔migration
adaption - correct answer ✔✔a physical trait that increases an organism's ability to survive in its
environment
mass extinction - correct answer ✔✔sudden elimination of a species due to a catastrophic
event
punctuated equilibrium - correct answer ✔✔rapid evolutionary change
evolution - correct answer ✔✔biological change over time that causes descendants to be
different from their ancestors
descent with modification - correct answer ✔✔principle of natural selection that explains how
beneficial traits should become more common over time, causing a change in allelic frequencies
homologous structures - correct answer ✔✔body structures that are similar in orientation, but
completely different in function due to organisms living in different environments
embryology - correct answer ✔✔study of embryological development in vertebrates that has
led to support the theory of common ancestry among vertebrates
