BIO 101 Module 1 Discussion Life’s Extreme Environments TUI
Discussion: Life’s Extreme Environments
Discussion Topic
Everything we know about life comes from studying our own
planet. Recent discoveries about life forms in extreme environments have
renewed scientists’ interest in looking for life elsewhere.
Organisms that thrive in a wide variety of harsh
conditions –called extremophiles—are broadening scientists’ understanding of
the diverse environmental conditions life can withstand. Scientists have had to
modify their theories and expand their view of what types of environments are
habitable based on the new information presented by the existence of
extremophiles.
Watch the following 1.5 minute NOVA video on
extremophiles. Complete your initial post by answering the questions below:
Life’s Extreme Environments
- What is an extremophile?
- What kinds of extreme environments can life thrive in?
- Explain why the study of extreme environments on
Earth is important to the search for life on other planets. Do you think
this could change the way scientists view our understanding of life? Why
or why not?
