Would you have agreed with the theory of evolution if you lived at the time it was originally presented? Do you believe it is well supported now? Why or why not?

Theories are backed by lots of evidence.

Let’s look at the evidence Darwin used to support

Evolution by Natural Selection.

Darwin’s Evidence

●Fossil Record showed
changes over time

○Today there are many
more fossils to look at

●Anatomical Evidence

○Finches had different
beaks based on the
food they had
available in their
environment

Evidence Available Today

●DNA Evidence

○Strongest piece of
evidence

○Shows how similar /
different species are

●Embryo Evidence

○All organisms start
out the same, so
could have been
related
