Warm-up 2/6:

1. Warm-up 2/6: • What are the three experiments to discredit the ideas of spontaneous generation & the vital force? • Include the names of the experimenters and what experiments were conducted. • What was the composition of the Earth’s early atmosphere? • Which scientists wrote a paper in the 1920’s predicting that the atmosphere could be responsible for organic molecules? • Which scientist recreated the early atmosphere to synthesize primordial soup?

2. Exam • Wednesday February 12. • Study Guide: Due Tuesday February 11. • Will be stamped on 2/11 & Collected on 2/12 • Intervention/Study Lab • Directed Test Prep: 45 minutes • In this classroom • Monday: 2:45- 3:30 pm • Tuesday: 6:50 – 7:35 am • 5% Extra credit on test • Up to 75% Test Score • Must be on time, stay 45 min, complete all assignments

3. Flightless Bird • A Flightless bird ends up on two different islands. The bird is medium height, has a medium length weak beak and is slow moving. • How will the bird adapt on Islands #1 & #2: • Make 2 columns. • How many birds can survive without competing for food? • For Each Bird Describe: Amount of feathers, Beak style, speed and height. • Hints: Weak Beaks are OK for insects. Strong Beaks are required for seed pods. • Short beaks are Ok for food on the ground. Long Beaks are required for food inside bark.

4. Make 2 Columns: 1 for each Island Island #1 Island #2 Climate: Cold and Wet Food Sources: Plants in seed pods in tree bark. Slow moving insects on ground Slow insects inside tall tree bark. • Climate: Hot and Dry • Food Sources: • Plants in seed pods on ground. • Fast moving insects on ground • Slow insects inside tall tree bark.

5. Warm up 2/7 • For your flightless birds from yesterday’s activity. • Did the birds change to be more similar or more different? • What things increased the birds similarities? • What things increased the birds differences?

6. 15-3 Notes: EVOLUTION IN ACTION pp. 308-311

7. EVOLUTION DEFINED… • Evolution of a population is due to environment and the interactionof other species

8. Artificial Selection • humans breed for specific traits causing differences in species (i.e. dog breeding)

9. Types of Evolution • Convergent evolution: • Organisms with very different ancestors become more alike due to a common environment • compare analogous structures: same functions but different development • (EX: fish and whales)

10. Ex: whale and fish, bird and insect

11. Types of Evolution • Divergent evolution: populations become more and more dissimilar to adapt to the environment • -compare homologous structures: similar body part but may have different functions

12. Adaptive Radiation: Population undergoes divergent evolution until it fills all areas of the environment

15. EX: Rough-skinned newt and garter snake • Newt evolved to produce neurotoxins then the snake evolved resistance to this toxin through genetic mutations. Birds and flowers, Humans and bacteria are other examples

16. COEVOLUTION • When two species each evolve in response to each other over a long period of time.  • This leads to a close relationship

18. 4-square Model Word

19. Classwork • “Types of Evolution Tree Map” • Vocabulary 4-squares • Convergent evolution • Divergent evolution • Artificial selection • Coevolution Word
