Natural Selection: 100

Define natural selectionOrganisms w/ advantageous traits

survive longer, and pass those traits to offspring.

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.

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

Natural Selection : 400

Natural selection acts on _________________.phenotype

Adaptations: 100

What is adaptation that some male birds

have to attract mates?Brightly colored feathers

Adaptations : 200

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

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

Adaptations : 400

What are some adaptations for genetic

drift?There are none. Genetic drift is random! (Ex: environmental disaster)

Speciation: 100

What is speciation?

The formation of a new species

Speciation : 200

What is a group of animals that can only breed with

each other? A species

Speciation : 300The image below shows

speciation caused by what?

Geographic barrier

Speciation : 400

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

Human Evolution: 100

True or False: Humans are primates

True

Human Evolution : 200

What is the evolutionary relationship between humans

and Neanderthals?

We share a common ancestor, but are not descended FROM Neanderthals

Human Evolution : 300

How many species of hominids are present today?

Just 1, US! (homo sapiens)

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
