Aoccdrnig to a rscheearch at Cmabrigde
Uinervtisy, it deosn't mttaer in waht oredr the
ltteers in a wrod are, the olny iprmoetnt tihng is

Many scientists use
embryologic
developments as
evidence of
evolution from a
common ancestor.

diagram on the
right, at which step
can the species of
one embryo first be
distinguished?
Many scientists use DNA sequences to
determine ancestral relationships.

Questions:
1. Explain why you chose to shade part of
your map as once covered in water?
(What fossil clues helped you?)
Questions:
2. Describe
how the
environment
changed over
time.
Questions:
3. One member of the team wished to look
for dry climate fossils of dry climate plants
at the site. Which layer or layers do you
think would be most likely to yield fossils of
this kind? Explain your answer.
Questions:
4. When the paleontologists were analyzing
these data, they proposed several hypotheses
to explain the changing climate. One of them
suggested that tectonic uplift had occurred,
causing the area to gain elevation over time.
A second paleontologist disagreed, stating
that the area probably lost elevation over
time. Whom do you agree with? Explain your
answer.
