Match the following terms with the correct definition.

• Adaptation

• Heritable characteristics the increases the organism's ability to survive and reproduce in an environment.

• Evolution

• Body parts that share a common function, but not structure.

• Biogeography

• Selective Breeding of plants and animals to promote the occurrence of desirable traits to offspring.

• Analogous Structures

• Change over time; the process of which modern organisms have decided from ancient organisms.

• Artificial Selection

• Study of past and present distribution of organisms.

What was the most significant adaptation Charles Darwin observe, while studying the differences between Finches?

• The different beak shapes the different Finches had.

• The different shapes and sizes of eggs each type of Finches laid.

• How all the Finch Embryos were the same for each type of Finch.

Match the following terms with the correct definition.

• Natural Selection

• Process by which organisms that are most suited to their environment survive and reproduce successfully.

• Homologous Structures

• How well an organism can survive and reproduce in its environment.

• Fossils

• Structures that are similar in different species on common ancestry.

• Vestigial Structures

• Preserved remains of ancient organisms.

• Fitness

• Structure that is inherited from ancestors but has lost much or all of its original function.

A theory is an idea supported by lots of evidence.

• True

• False

​ (a)   is when a common ancestor splits into many different species, where each is adapted for slightly different habitats. However, when a species from different ancestors evolve similar traits due to similar environmental pressures it is ​ (b)   .

• Divergent Evolution
• Convergent Evolution
• Theory
• Artificial Selection

The Theory of evolution is based on _____ changing in specific environments over time.

• Fossils

• Organisms

• Natural Selection

The beak of a bird, just like the beak of a giant squid evolved to serve the same function and independently. This is an example of_____.

• Analogous Structures

• Natural Selection

• Homologous Structure
