The fossil record provides evidence that

• Fossils cannot be dated.

• All species were formed during Earth’s formation and have changed little since then.

• The fossilized species have no connection to today’s species.

• Older species gave rise to more-recent species.

Review the diagram which shows the outline of two continents. The outlines of the continents seem to correspond in shape where indicated by the arrows. Which is the best inference that can be made from this?

• The continents have similar geography and climate.
• The continents have similar weather patterns.
• The continents were once joined together in a large land mass.
• Africa contains more fossils than South America.
