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.

GameBoard

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.

GameBoard

Darwin’s 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

Darwin’s 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.

Darwin’s 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).

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:Ex: stripes of a tiger to make it more stripes of a tiger to make it more camouflage, the long legs of an ostrich camouflage, the long legs of an ostrich

to increase speed, etc.to increase speed, etc.GameBoard

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.

GameBoard

Evidence of Evolution 300 - Answer

Homologous structures- From a common ancestor

GameBoard

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.

GameBoard

Evidence of Evolution 500 - Answer

1. Fossil record2. Comparative anatomy (homologous structures AND

vestigial structures)3. Comparative embryology4. Comparative Biochemistry (DNA)5. Geographic Distribution

***Why is each evidence for evolution??? Be specific (I’m leaving this one up to you )

GameBoard

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

Disruptive selection

GameBoard

Shaping Evolutionary History 300 - Answer

Directional Selection

GameBoard

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. GameBoard

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

b) Convergent evolution

GameBoard

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.
