Answer 1

Theory that describes the way in which organisms change over time as a result of natural selection.

Question 2

Answer 2

Process whereby organisms that are better adapted to their environment are more likely to pass on their characteristics through their genetic makeup.

Question 3

Palaeontology

Answer 3

The study of the history of life on Earth based on fossils. Is evidence for evolution as similarities and advancements can be seen in the earliest of fossils.

Question 4

Fossils record

Answer 4

Collection of fossils documenting the history of life on Earth

Question 5

Comparative anatomy

Answer 5

Study of similarities and differences in the anatomy of different living species.

Question 6

Homologous structure

Answer 6

Structure that appears superficially different in different organisms, but has the same structure. Eg pentadactyl limb of vertebrates.

Question 7

Divergent evolution

Answer 7

Describes how different species can evolve from a common ancestor. Includes different adaptive features.

Question 8

Comparative biochemistry

Answer 8

Study of similarities and differences in proteins and other molecules that control life processes. Can help to determine evolutionary links
