Unit 10 Review - Evolution

The law of superposition states

• the oldest rock layer is on the top, the younger rock layer is on the bottom
• rock layers are always in sequence from oldest to youngest
• the youngest rock layer is on the bottom and the oldest is on the top
• the oldest layer is on the bottom and the youngest is on the top when it is undisturbed

Ostrich wings are examples of

• homologous structures
• vestigial structures
• adaptations
• traits

Dolphins have the same arm structure as wolfs, what type of evidence for evolution does this represent?

• DNA
• vestigial structures
• homologous structures
• embryology

What is embryology?

• the age of organisms
• the oldest stage of development
• the life span of an organism
• the earliest growth stage of development

Why do embryologist study embryos?

• to see if they are related
• to understand adaptations
• to determine the age
• to learn what parents are vestigial

Change over time is

• evolution
• generation
• growth
• biogenesis

Natural selection is

• survival of the fittest
• humans change
• two species are the same
• more animals survive

This makes an organism more suited to its enviornment

• species
• lifespan
• adaptation
• mutation

What is one reason that strawberries are surviving in the winter season?

• they have larger leaves
• they have genetic variations allowing them to be resistant to cold
• they reproduce more
• the color is dark

Who was Charles Darwin?

• A naturalist who came up with the theory of evolution
• A scientist who studied plants
• A geologist who looked at rocks and fossils
• A paleontologist who studied dinosaurs
