  • how forensic scientists take advantage of genomic
    variations in noncoding regions of DNA
  • the techniques of polymerase chain reaction (PCR)
    and gel electrophoresis
  • Introduction In recent years, law enforcement
    has been revolutionized by molecular biology.
    When human tissues are left behind at crime
    scenes, these tissues can be collected and
    processed to yield samples of DNA, which can then
    be treated to isolate specific DNA fragments that
    are highly variable in the human population.

  •  
  • Examine the graphs in the Lab Book, and describe
    any trends you observe among kelp, purple sea
    urchin, and sea otter populations.
  • What happened to all three populations when
    catastrophe struck the sea otters? Which
    populations were wiped out, and in what order?
  • Why do you think the removal of the otters caused
    the other two populations to crash as well?

  •        
  • There is a fierce competition among individuals
    within any species, humans included, to gain
    access to reproductive privileges. The fittest
    a term that signifies the largest, prettiest,
    and most sexually attractive members, succeed in
    predominantly mating and having offspring, while
    the less attractive ones often do not. What is
    the role of such sexual selection from an
    evolutionary standpoint?

    Primate Color Vision by Gerald H. Jacobs and
    Jeremy Nathans, Scientific American, April 2009

    the framework of Darwinian evolution, how natural
    selection crafted such an organ.

  •      
  • How do you think we could trace back the
    evolution of organs within our body by hundreds
    of millions of years from our reptile ancestors
    by examining coevolution patterns and fitness
    landscapes?Discuss, for instance, the missing
    link, Tiktaalik, that has made headlines around
    the world (see Your Inner Fish by Neil
    Shubin).What kind of selection pressures could
    have been at work here, based on species
    adaptations, climate changes, and shifting
    landmasses?

    evolution of vertebrates.- Description of the
    primate adaptations for living in trees.-
    Comparison of the three main groups of primates,
    noting examples of each.- An explanation as to
