GCSE Evidence for Evolution

The remains of organisms from millions of years ago that are found in rocks, peat, ice or amber are called:

• Dinosaurs

• Fossils

• Igneous rocks

• Waste

A now widely accepted theory that has been supported by evidence such as fossils, the theory suggests organisms can change over time due to natural selection. What is the name of this theory?

• The theory of natural selection

• The theory of evolution by natural selection

• Gene theory

• The theory of acquired inheritance

Fossils have been found that are very similar to existing organisms, suggesting modern organisms may have __________ from or share a common ancestor with these ancient organisms.

• Evolved

• Selectively bred

• Changed

• Devolved

Footprints, burrows, shell impressions, rootlet traces are preserved as fossils known as:

• Ice

• Trace fossils

• Amber

• Artificial fossils

Issues with the fossil record includes: (Choose 3)

• Fossils are not real

• Scientists are unable to accurately estimate the age of fossils

• Not all organisms will fossilise

• Fossils will not form if the conditions for decay are present

• Some early life forms were soft-bodied so have not left fossils

When organisms die they typically _____________ due to the action of microbes such as bacteria, however _____________ may not occur if conditions for _____________ are absent.

• Digest

• Decay

• Respiration

• Destruction

True or false?

Fossils will form when there is plentiful oxygen.

• True

• False

True or false?

Fossils can form when parts of an organisms are replaced by minerals.

• True

• False

What is the process where variation gives rise to phenotypes that are best suited to an organism's environment, increasing the chances that the organism will successfully reproduce.

• Natural Selection

• Artificial Selection

• Selective Breeding

• Acquired Inheritance

Differences in the characteristics of individuals in a population is called:

• Mutation

• Variation

• Selection

• Evolution
