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
