Mystery of Life

1. Mystery of Life Unit 2-2 Ms. Darlak

2. Warm-up 03/05 • The dinosaurs in Jurassic Park are portrayed based on what scientist proposed based on fossil evidence of them. (velociraptors, diplosaurus, triceratops, brachiosaurus, brontosaurus, and t-rex) • Do you believe all the movements, sounds and behaviors of these dinosaurs depicted in the film? • What were the most believable scenes? • What were some unbelievable scenes?

3. Agenda 03/05 • The Lost World Activity • Jurassic Park Essay due Tues. • Scholarly Article Review Due 3/16

4. Warm-up 03/06 • What kind of diet does your specimen eat? • Hint (What kind teeth do they have?) • Is your specimen a predator or prey? • Hint (Where are the eyes located on the face?) • Does your specimen walk on four or two legs? • Hint (Where are eye in skull? Is the skull flat or more rounded?)

5. Agenda 03/06 • Lost world Activity • Due at end of class • Jurassic Park Essay due Today. • Scholarly Article Review Due 3/16

6. Warm-up 03/07 • What do you think scientists use to categorize hominid fossils in the human evolutionary tree? • What characteristics would make a fossil more closely or more distantly related to humans? • Was it Bipedal? • Do its teeth and jaws indicate that its diet was made up of harder or softer foods? • How large was its brain?

7. Agenda 03/07 • Intro to Human Evolution • Bones of Contention (Computer Lab)

8. What is a Hominid vsHominin? • Hominid • Group consisting of all modern and extinct Great Apes. • Examples: modern humans, chimpanzees, gorillas, and orangutans plus all their immediate ancestors • Homindae is taxonomical the family • Hominin • Group consisting of modern humans, extinct human species, and all our immediate ancestors • Examples: members of genera Homo, Australopithecus, Parathropusand Ardipithecus

10. Who’s who in Human Evolution

11. Bones of Contention Your Task: • Use the database to classify each of ten mystery fossils by comparing them to fossils of known hominid species. Or, if the fossil is unique, assign it a species name of your choice. • Compare and defend their classifications. • Revise their findings if necessary. Link

12. Computer Lab B • Use Darlak4sceince for links.

13. Warm-up 03/08 • In Bones of Contention, what did you find out about Mystery bone #1? • How would you classify it? More closely related to us or chimpanzees? Why? • How did scientists categorize it? • Let’s see……

14. Mystery Fossil #1 • Scientists gave this fossil the name Sahelanthropustchadensis. • Though its foramen magnum is positioned further toward the back of the skull than more recent bipeds, many scientists note that its slightly forward position shows that it was bipedal, the earliest known biped to date. • Still, scientists disagree about precisely where this species falls in our ancestral family tree. Some scientists think Sahelanthropustchadensismay represent a common ancestor of humans and chimpanzees; others think it could be their relative but not an ancestor; still others question whether it even belongs to the hominid family tree.

15. Agenda 03/08 • Becoming Human Part 1

16. Becoming Human Part 1 (Nova) • First Steps: Six million years ago, what set our ancestors on the path from ape to human? • Link
