Evolution & Classification 2022-23

Which statement is true?

• Species with similar evolutionary histories are not classified together.
• Species with different evolutionary histories are classified more closely together.
• Species with similar evolutionary histories are classified more closely together.
• Species with similar evolutionary histories are classified in the same species.

To determine whether two organisms are related, scientists may compare the ___________ of their cells.

• size
• nucleic acids
• shape
• number

____________________ is the process by which individuals that are better adapted to their environment are more likely to survive.

• evolution
• natural selection
• branching tree diagram
• convergent evolution

A(n) ____________ is usually a homologous structure that is shared by all organisms in a group.

• cell
• species
• branching tree diagram
• shared derived characteristic

The theory of evolution was proposed by

• Carolus Linneus
• Albert Einstein
• Charles Darwin
• Darlis Charwin

If two species have very similar structures, they may have evolved from

• the same parent
• a common ancestor
• a branching tree diagram
• similar offspring

Branching tree diagrams tell you the order in which a specific set of characteristics may have evolved.

• True
• False

Similar looking organisms that are NOT related are an example of

• natural selection
• convergent evolution
• divergent evolution
• common ancestor

Two groups of organisms with similar characteristics may share

• a common ancestor
• an evolutionary history
• both a common ancestor and evolutionary history
• neither a common ancestor and evolutionary history

Of the following, the best definition of evolution is

• a rapid change in species over time
• the adaptation of an organism to its environment
• the ability of an organism to survive and reproduce
• a gradual change in a species over time
