Fossils - Evolution and Behaviour Quiz

What are fossils?

• Minerals found in rocks

• Types of sedimentary rocks

• Traces of past life

• Types of volcanic ash

What is the chance of fossilization dependent on?

• Proximity to sediment

• Proximity to water

• Proximity to fire

• Proximity to air

Answer explanation

The chance of fossilization is dependent on proximity to sediment, as this is necessary for the preservation process to occur.

What is permineralization in the context of fossil formation?

• Hard minerals leach out of rocks and impregnate the remains

• Soft minerals dissolve in water

• Fossils are formed in the air

• Fossils are formed in space

How can fossils be dated using volcanic ash?

• Paleomagnetic dating

• Relative dating

• Carbon dating

• Potassium and Argon dating

What does the molecular evidence from fossils reveal?

• Information about current species only

• No information about evolution

• Decreasing amounts of information about evolution

• Increasing amounts of information about evolution

What is the characteristic of the Cambrian 'explosion'?

• Rapid evolution

• Slow evolution

• No evolution

• Stagnant evolution

What does the fossil record show about evolution?

• Lineages appear, change, and disappear

• No changes in lineages

• Lineages only appear

• Lineages remain constant
