Scientific progress requires that we clearly define the question we wish to answer. A clear, sharp definition of a scientific question is often the most difficult step in the process of discovery. Which of the following is the most accurate and complete description of the specific scientific question or problem we will address in this course?

a.
Humans have no individually unique properties; however, the specific combination of properties we have is not seen in other animals and these properties evolved very rapidly after our divergence from the other apes.

b.
Humans have specific objectively measurable properties no other animals have and we acquired these properties over a short evolutionary time period when other ape lineages were changing relatively little.

c.
Humans have no individually unique properties; however, the specific combination of properties we have is not seen in other animals and these properties evolved very slowly after our divergence of the other apes.

d.
Humans have objectively measurable properties no other animals have and we acquired these properties over a long period of slow change after our lineage's divergence from other ape lineages.
