In each of the conditions below identify the process of natural
selection may be stabilizing, directional or disruptive.
1) Malaria management protocols include regular
spraying of pesticides to kill the mosquitoes that carry the
parasite that causes this disease. For many years these
global spraying programs helped to keep malaria under good control.
However, in the past 10 years malaria has resurged, often to
epidemic levels, due to an explosion in the population of pesticide
resistant mosquitoes.
a) Directional selection
b) Stabelizing selection
c) Disruptive selection
2) Seasonal floods regularly kill off most members
of a frog population. Over time two distinct sub species
emerge. One species is very like the original population
except that it has longer claws on its front legs that allow it to
burrow safely into the sediments during floods. The other
species has suction cup like structures on its toes that allow it
to live above the floods in the trees.
a) Directional selection
b) Stabelizing selection
c) Disruptive selection
3) 5600 humans have been traveling in the
controlled environment of an interstellar starship for over 500
years.
a) Directional selection
b) Stabelizing selection
c) Disruptive selection
4) Animals with low metabolic rates are slow
moving, sluggish and survive on very few calories, but are poor at
evading predators. Animals with high metabolic rates are
energetic, vigilant, and good at evading predation, but quickly die
when high calorie foods are unavailable. Human evolution has
favored a more metabolically moderate individual that maintains
moderate activity levels on as few calories as
possible.
a) Directional selection
b) Stabelizing selection
c) Disruptive selection
