In your foldable:
Color each event
Add the name of each event
Label the time (on the clock model)
Clock Model Key:
All 4.6 billion years represented in 12 hours. Each hour represents 383 million years.
Use pgs 73-77 in FOSS: Heredity & Adaptations to fill out the table in your foldable. You can also find out more about major extinction events on the American Museum of Natural History Website.
Use the graph to the left to answer the two questions in your foldable.
1) Describe what a mass extinction looks like on the graph.
2) Why would the number of families be a good indicator of biodiversity in the fossil record? Remember these are taxonomic families!
Evolution: the process of biological change by which populations (not individuals!) become different from their ancestors over many generations.
Common Ancestry: the idea that two or more species evolved from a common ancestor.
Ex:) Humans and Chimpanzees share a common ancestor in the Hominini genera.
Anatomy: An organisms body structure and its structural traits.
Using what you have learned from the activities in this unit (like Whale of a Tale), or using this link, How is DNA used to infer how closely related species are? Why is DNA always the most important piece of evidence for determining how closely species are related?
Using what you have learned from the activities in this unit (like embryology) What evidence is left behind in early embryos that all species have a common ancestor?
Using what you have learned from the activities in this unit (like Comparative Anatomy), what can we learn from bone structure and placement about how fossil animals would use their limbs?
