7.1 Evidence for Evolution (Teachers Pet)

What type of rock contains the most fossils?

• Sedimentary rock

• Basalt rock

• Igneous rock

• Metamorphic rock

What is the law of superposition?

• All rock layers are of the same age

• Older layers are on the bottom and younger layers are on top

• Younger layers are on the bottom and older layers are on top

• Rock layers do not indicate any age

Which dating method counts the rings in a tree?

• Radiometric dating

• Amino acid dating

• Luminescence dating

• Dendrochronology

What does the presence of vestigial structures suggest?

• Structures fully functional in current organisms

• Newly developed structures

• Structures unrelated to evolution

• Evolutionary remnants of functional structures

What are homologous structures?

• Structures that appear during embryological development

• Structures in different species with a common ancestor

• Random structures without any evolutionary significance

• Structures with the same function but different evolutionary origins

Which species is used as a transitional species linking birds and reptiles?

• Archaeopteryx

• Pterodactyl

• Velociraptor

• Tyrannosaurus Rex

What is the purpose of the molecular clock in evolutionary studies?

• To determine the absolute age of fossils

• To measure the speed of continental drift

• To measure the rate of mutations and determine evolutionary relationships

• To keep time in geological studies

What is the significance of analogous structures?

• They perform similar functions but do not have a common evolutionary origin

• They have a common evolutionary origin

• They are unrelated in function and form

• They are always vestigial

What does absolute dating help to estimate?

• The numerical age range of rocks or fossils

• The relative age of rocks

• The color and texture of rocks

• The size of the fossils

What was the initial thought about the human appendix?

• It was crucial for digestion

• It was a newly developed organ

• It was a vestigial organ

• It was unrelated to any function
