The glyptodont fossils and living armadillos that Darwin observed during his voyage are related to which pattern of biodiversity?

• species vary globally

• species vary locally

• species vary over time

• all of these patterns

Evolution works by 

• individuals changing to suit their environment
• Individuals learned new traits and pass them on
• sudden change in the environment cause a species change 
• small changes pass down through many generations

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Dogs such as Chihuahuas are examples of....

• Artificial Selection 
• Natural Selection 
• Mutations 

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

The study of embryos and their development is called

• embryology

• biology

• avianology

• ecology

Structures found in different species derived from the same embryonic/ancestral origin and are similar in basic structure and development are called

• homologous structures

• analogous structures

• evolutionary structures

• homeopathic structures

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals
• They live in similar environments
• They have a common ancestor
• All organisms resemble humans

Bird wings and butterfly wings are an example of

• Homologous structure
• Analogous structure
• Mimicry
• Camoflague
