Warm up 2 6

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?

Flightless bird

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.


Make 2 columns 1 for each island

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.


Warm up 2 7

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?

15-3 Notes: EVOLUTION IN ACTION

pp. 308-311


Evolution defined

EVOLUTION DEFINED…

  • Evolution of a population is due to environment and the interactionof other species


Artificial selection

Artificial Selection

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


Types of evolution

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)


Warm up 2 6

  • Ex: whale and fish, bird and insect


Types of evolution1

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


Warm up 2 6

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


Warm up 2 6

  • 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


Coevolution

COEVOLUTION

  • When two species each evolve in response to each other over a long period of time. 

  • This leads to a close relationship
