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?
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)
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
slide12
Adaptive Radiation: Population undergoes divergent evolution until it fills all areas of the environment
slide15
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
