Question 2
Complete the statement below.(1 point)
Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family’s geographical origin provide evidence that all these animals
Question 3
In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered species of big cat. Based on the evidence, scientists hypothesize that big cats branched off from smaller wild cats about 6 million years ago. Which of these resources did the scientists most likely rely on to form their hypothesis?(1 point)

Question 4
Natural selection is the process through which populations of living organisms adapt and change.
An example of this is the peppered moth, which maintained it's ability to camouflage itself (hide in it's environment) through natural selection of darker colored wings in response to a darkening of it's environment.
Which of the following would be another example of natural selection? (MARK ALL THAT APPLY)
