2 Natural Selection: 100 Define natural selection Organisms w/ advantageous traits survive longer, and pass those traits to offspring.

3 Natural Selection : 200 During the natural selection activity (jelly beans) why did we end up with more brown jelly beans than green? “Organisms” had camouflage adaptation to make them less visible to predators.

4 Natural Selection : 300 How did natural selection occur with giraffes? Giraffes w/ longer necks could eat more/ were better suited to environment, left more offspring who had long necks

5 Natural Selection : 400 Natural selection acts on _________________. phenotype

6 Adaptations: 100 What is adaptation that some male birds have to attract mates? Brightly colored feathers

7 Adaptations : 200 How did peppered moths adapt to their environment after industrialization? Dark colored moths became the dominant phenotype

8 Adaptations : 300 What are some adaptations that polar bears have to help reduce heat loss? Large volume to produce lots of heat, small surface area to prevent heat loss, thick fur coat, layer of blubber

9 Adaptations : 400 What are some adaptations for genetic drift? There are none. Genetic drift is random! (Ex: environmental disaster)

10 Speciation: 100 What is speciation? The formation of a new species

11 Speciation : 200 What is a group of animals that can only breed with each other? A species

12 Speciation : 300 The image below shows speciation caused by what? Geographic barrier

13 Speciation : 400 What is it called when species can no longer breed and produce viable offspring. A reproductive barrier

14 Human Evolution: 100 True or False: Humans are primates True

15 Human Evolution : 200 What is the evolutionary relationship between humans and Neanderthals? We share a common ancestor, but are not descended FROM Neanderthals

16 Human Evolution : 300 How many species of hominids are present today? Just 1, US! (homo sapiens)

17 Human Evolution : 400 “Lucy” is an Australopithecus, the oldest known species of hominids. What did they do that we do? Stood upright and walked on 2 legs
