Which of the following statements about natural selection is most accurate?
a) Mammals in cold climates need warm fur so they evolve thick coats.
b) Natural selection results in organisms that are perfectly adapted to their environment.
c) Natural selection can only act on populations with genetic variation.
d) Natural selection is a random process. - (answer)c) Natural selection can only act on
populations with genetic variation.
In the case study for Tutorial #1, you learned about the "Evolution Canyons" that exist in the
mountains of Israel. Singaravelan et al (2010) investigated how the melanin content of the hair of
spiny mice (Acomys cahirinus) has evolved in response to alternative selection pressures
inflicted by contrasting colored habitats of Evolution Canyon I (ECI). The results of this study
show that spiny mice that live on the African slope of ECI have
a) higher pheomelanin than eumelanin content in their hair.
b) lower pheomelanin than eumelanin content in their hair.
c) coloration that is the same as spiny mice living on the European slope.
d) darker hair than their counterparts on the European slope. - (answer)a) higher pheomelanin
than eumelanin content in their hair

b) C12H24O12
c) C12H22O11

Sweat plays an important role in thermoregulation due to the high heat of vaporization of water.
That is, it takes energy to not only raise the temperature of water, but additional energy is
required to make the phase change from water to gas. In individuals with HED (hypohidrotic
ectodermal dysplasia), sweat gland numbers are reduced. Predictably, what symptoms occur in
HED-affected individuals?
