Congratulations! You are in charge of the future evolu-
tion of life on the earth. What are the three most impor-
tant things you would do?
CRITICAL THINKING
1.
An important adaptation of humans is a strong oppos-
able thumb, which allows us to grip and manipulate
things with our hands. Fold each of your thumbs into the
palm of its hand and then tape them securely in that po-
sition for an entire day. After the demonstration, make a
list of the things you could not do without the use of
your thumbs.

How would you respond to someone who tells you
that he or she does not believe in biological evolu-
tion because it is “just a theory”?
b.
How would you respond to a statement that we
should not worry about air pollution because nat-
ural selection will enable humans to develop lungs
that can detoxify pollutants?
3.
How would you respond to someone who says that
because extinction is a natural process, we should not
worry about the loss of biodiversity?
