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
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 : 400
What is it called when species can no longer breed and produce viable offspring.A reproductive barrier
Human Evolution : 200
What is the evolutionary relationship between humans
and Neanderthals?
We share a common ancestor, but are not descended FROM Neanderthals
