Transcript What is Natural Selection?

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
that the frist and lsat ltteer be at the rghit pclae.
The rset can be a total mses and you can sitll
raed it wouthit porbelm.
Tihs is bcuseae the huamn mnid deos not
raed ervey lteter by istlef, but the wrod as a
wlohe.
amzanig huh?

Many scientists use
embryologic
developments as
evidence of
evolution from a
common ancestor.
Based on the
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.
Based on the
diagram on the
right, which of
the organisms
are the most
closely
related?

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.
