Exploring Evolution: Evidence and Relationships

What does comparative embryology compare?

• Fossil records of embryos

• Embryos of different species

• Metabolic processes in adults

• Genetic sequences of adults

Which set of bones is shared across different species according to anatomical evidence?

• Rib bones

• Skull bones

• Vertebrae

• The basic set of limb bones

What is the closest living relative of a bear?

• Dog

• Wolf

• Seal

• Cat

What kind of organisms share genetic sequences?

• All life forms

• Only multicellular organisms

• Only vertebrates

• Only mammals

What does the fossil record provide evidence for?

• The unchanging nature of species

• Evolution and change over time

• The recent origin of all species

• The absence of common ancestry

How do scientists determine the age of fossils?

• By comparing DNA

• Through chemical evidence

• By observing the size of the fossils

• Using comparative embryology

What new evidence changed our understanding of dinosaurs' closest living relatives?

• DNA evidence

• Fossil evidence of feathers

• Structural evidence of bones

• Comparative embryology

Why is science considered a growing collection of knowledge?

• It constantly seeks new evidence

• Because it never changes

• Because it ignores new discoveries

• Due to its reliance on ancient texts
