Proof of Evolution

How do the fossils found in the upper layers of Earth compare to present-day organisms?

• They are identical to present-day organisms

• They are completely different from present-day organisms

• They tend to look more like present-day organisms

• There is no relation to present-day organisms

What can be inferred about the relationship between organisms that have more similar DNA, amino acid sequences, proteins, and enzymes?

• They are less likely to be closely related.

• They are more likely to be from the same habitat.

• They are more likely to be closely related.

• They have no significant relationship.

What does the presence of vestigial structures in an organism imply?

• The organism is not fully evolved

• The organism's environment has remained constant

• The organism's ancestors had different adaptations that are no longer functional

• The organism has no evolutionary history

What are vestigial structures?

• Structures that are fully functional in an organism's environment

• Features that were an adaptation for the organism's ancestor and are now non-functional

• Structures that have evolved recently

• Features that are essential for an organism's survival

Missing Link

• gaps in the fossil record that provide proof of Evolution

• similar structures that related species have inherited from a common ancestor (example – bones in bird’s wing, dolphin fin, and dog leg are very similar)

• process where scientists look at the half-life of chemicals contained in rocks around a fossil to determine the age of that fossil.

• the disappearance of all members of a species from Earth

is there evidence of evolution

• No, there is no evidence of evolution.

• Yes, but there is very little

• Not really, there is some but it proves nothing

• Yes, there is a lot of proof behind evolution.
