In the Insight into National Geographic Explorer, Dr. Hand suggests that studying life in extreme
environments is important for what reason?
a. It can improve our understanding of earth’s early evolution
b. Extreme environments have highly adapted organisms
c. These environments could mimic conditions on other planets
d. New species of organisms are being discovered
ANS: C
It was thought that life could not exist in these harsh, dry, cold, environments but in the 70’s rocks
from Antarctica had complex microbial communities of lichens and cyanobacteria. Dr. Hand explains
that studying microbes is tricky because if you bring the rocks up from the extreme environments they
often change what they’re doing. Information can be found in the section Insight from a National
Geographic Explorer
