Which is the best possible hypothesis for explaining changes in cortical robusticity over time? a.) The decrease in cortical robusticity associated with the appearance of modern humans was rapid and dramatic and resulted in more lightly constructed skeletons. b.) The increase in cortical robusticity associated with the appearance of modern humans was gradual and resulted in larger brain size coupled with a greater ability to deal with predators l. c.) The decrease in cortical robusticity associated with the appearance of archaic Homo sapiens is a part of a long term trend beginning with australopithecines and ending with modern Homo sapiens. d.) None if these statements are an appropriate hypothesis for changes seen in cortical robusticity.

Which of the following best describes the evolution of smell in chordates?     A) Ancestrally, jawless fish had few ancestral scent genes that coded for receptors resembling a combination of water and air receptors. Subsequently these genes were duplicated and specialized through natural selection either for use in water or air.     B) Ancestrally, all olfactory receptors where specialized for water as the ancestor of all vertebrates was aquatic. Only once did olfactory genes become duplicated and specialized and this was in the transition to land for receptors that work in air.     C) All chordates share the same number of scent receptor genes. However, they have become variously deactivated through natural selection due to either unuse or a tradeoff for sight genes.     D) None of the above.
