• Ranchers historically have used genetics to
  produce new varieties of cattle. Buffalo can
  tolerate both hot and cold temperatures but have
  meat that is not as tasty and tender as beef.
  Cattle that are subjected to severe temperature
  extremes produce meat that is neither tender nor
  good-tasting. What good qualities might a
  beefalo (cross between cattle and buffalo)
  possess?
• Animals that tolerate cold but do not have
  good-tasting meat
• Animals that tolerate heat and cold but do not
  have good-tasting meat
• Animals with good-tasting meat but not tolerance
  to heat
• Animals that tolerate heat and cold and have
  good-tasting meat

53
D. Animals that tolerate heat and cold and have
good-tasting meat
54

• Changes in DNA are known as mutations and can
  sometimes produce beneficial changes in
  populations. A mutant form of the normally
  light-colored peppered moth is dark colored. The
  dark-colored moth blends in with soot-covered
  trees in heavily polluted areas. Why would the
  dark-colored mutation be beneficial in a polluted
  area?
• Dark-colored moths taste bad to most of their
  predators.
• Dark-colored moths produce more young than
  colored moths.
• Dark-colored moths cant be seen well.
• Dark-colored moths have a longer life span than
  light-colored moths

65
C. Dark-colored moths cant be seen well.
66
What most likely happened to species that are
found in the fossil record but have no living
members? A. They mutated to other species. B.
They never really existed. C. They became
extinct. D. They had offspring of a different
species.
67
C. They became extinct.
68
Finches found on the isolated Galopagos islands
are different species with different beak sizes
and shapes, but are otherwise similar to a finch
species found on the South American mainland.
What might be the cause of the differences in the
development of the beaks of these Galapagos
finches?
A. The original source of the finches B. The
differences in the types of nests the birds
built C The different types of food available on
the islands   D. The type of predators found on
the islands
69
C The different types of food available on the
islands

Final Jeopardy
What does survival of the fittest mean?
71
The organism best adapted to its environment
will survive to reproduce. The offspring will
have inherited traits that will make survival in
that environment possible.
