History of the Earth400 - Answer

• Once living organisms (contained Carbon) that are
  less than 100,000 years old.
• The half-life of Carbon-14 is approximately 5,700
  years, so there would be too little Carbon-14
  left to measure after 100,000 years.

32
History of the Earth500 - Answer

• As continents slowly moved, populations of
  species were separated. Those that adapted to
  new climates probably evolved into new species
  after many generations.

Game Board
33
Darwins Theory of Natural Selection 100 - Answer

• True

Game Board
34
Darwins Theory of Natural Selection 200 - Answer

• It shows that organisms have changed over time.
  Earth is old enough (4.6 billion years old) for
  these changes to occur.

Game Board
35
Darwins Theory of Natural Selection 300- Answer

• Maybe the different species of finches on
  different islands had once been part of the same
  species. They had adapted over time to the
  conditions on each island.

Darwins Theory of Natural Selection 400 - Answer

1. Variation
2. Heritability
3. Overproduction
4. Reproductive Advantage

Game Board
37
Darwins Theory of Natural Selection 500 - Answer

• Natural selection is one way of how evolution
  works. Evolution is how species change over time
  (generally due to natural selection).

38
Evidence of Evolution 100 - Answer

• Many answers could be correct as long as it is
  a characteristic that increases the survival and
  reproductive success of that animal.
• Ex stripes of a tiger to make it more
  camouflage, the long legs of an ostrich to
  increase speed, etc.

Game Board
39
Evidence of Evolution 200 - Answer

• When populations are separated by barriers such
  as rivers or mountains. They become isolated and
  will eventually evolve into separate species.

Game Board
40
Evidence of Evolution 300 - Answer

• Homologous structures
• - From a common ancestor

Game Board
41
Evidence of Evolution 400- Answer

• Analogous structures
• - They appear to be similar on the outside, but
  are different on the inside structurally
  (anatomically). They did NOT evolve from a
  common ancestor.

Game Board
42
Evidence of Evolution 500 - Answer

• Fossil record
• Comparative anatomy (homologous structures AND
  vestigial structures)
• Comparative embryology
• Comparative Biochemistry (DNA)
• Geographic Distribution
• Why is each evidence for evolution??? Be
  specific (Im leaving this one up to you ?)

Game Board
43
Shaping Evolutionary History 100 - Answer

• Random chance
• (NOT due to natural selection)
• - Natural disaster could wipe out a large portion
  of the population, or overhunting (elephant
  seals), or a small group moves away

Game Board
44
Shaping Evolutionary History 200 - Answer

• Disruptive selection

Game Board
45
Shaping Evolutionary History 300 - Answer

• Directional Selection

Game Board
46
Shaping Evolutionary History 400 - Answer

• Speciation
• - A new species evolves because they eventually
  evolve enough changes that they no longer
  reproduce with the original population.

Game Board
47
Shaping Evolutionary History 500 - Answer

• Adaptive radiation new species evolve from a
  common ancestor (branching tree), generally rapid
  growth as the organisms adapt to new conditions
• Convergent evolution unrelated species evolve
  similar adaptations (analogous structures), but
  they do not share a common ancestor

Game Board

• Vestigial Structures

Game Board
51

• Adaptive radiation
• Convergent evolution

Game Board
52
MISC 500 - Answer

• C. Though disruptive selects for the shortest AND
  longest necks, it is the only graph shown that
  does select for short necks. Stabilizing stays
  stable (middle lengths). The directional graph
  moves in the direction of the longer necks.
