Station 1
There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce.

3. What are the variations in the worm population?
4. What will the population turn to overtime?

Station 3
In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour. Jackals love to eat ostrich, and they can reach speeds of up to 35-40 miles per hour. A flock of ostrich will lay ~ 10 eggs (each mother only lays 1), but many rodents break into the eggs and eat the fetus before they hatch.

Station 5
Ryan believes that giraffes have long necks because the ones with long necks were able to reach the food, and those with short necks could not and died. The long necked giraffes reproduced, and soon all of the giraffes had long necks

Station 7
There are two types of rabbits: those that strictly eat grass and those that strictly eat berries and flowers. A drought occurs one year, and the plants have difficulty producing any extras (flowers, berries, etc.). They can only try and keep themselves green. The rabbits have had babies all year long but many are eaten by foxes or hawks due to the drought, many have starved to death.

It has been proved that peahens will choose males with brighter colors. There for, if they continue to only mate with the brightest males, then only the brightest males will pass on their genes, and then only the brightest of that generation will pass on their genes.

21. ________ Enable(s) an organism to blend with it’s surroundings
22. _________ Provide(s) protection for an organism by copying the appearance of another species.

Identify the following as being MIMICRY, CAMOUFLAGE, or BOTH
23. ___________The coloration of a flounder that allows the fish to avoid predators.
24. ___________ Involve(s) changes to the appearance of an organism.

Station 13
Some colonies of bacteria develop a resistance to an antibiotic resulting from a mutation that simplifies the bacteria's DNA instructions. This allows the bacteria to eat more types of food, including the antibiotic which previously would have killed them. While this is a helpful mutation for bacteria developing in the presence of antibiotics, placed in normal environments these bacteria are less viable than those without the mutation.

Station 15
The change in color of the peppered moth after the Industrial Revolution is a classic example of evolution in action.
When newly industrialized parts of Britain became polluted in the nineteenth century, smoke killed lichens growing on trees and blackened their bark.
Pale colored moths which had been well camouflaged before when they rested on tree trunks became very conspicuous and were eaten by birds. Rare dark moths, which had been conspicuous before, were now well camouflaged in the black background.
