Phylogeny of the Primates
As promised, you are going to get your chance to create a phylogenetic tree from some
molecular clock data. We are going to give you some mutation differences in DNA.
This is just like the bird phylogeny we did. Below is a table of REAL data. This date
represents difference in DNA. It is obtained by actually letting strands of DNA stick
together. The tighter they stick, the more closely their sequences align. In the table,
the higher the number, the less well it stuck, meaning the less closely aligned it was.
We can use these numbers to draw a phylogenetic tree. To make things simpler, the
data have been smoothed out a bit.

You can use these data just as we did with the bird data to create a phylogenetic tree
showing relationships between these primates. If you need to see how to do this again,
refer back to the assignment where we did this with bird DNA.

You will place the 7 organisms across the top above the 0 line. The scale on the left is
percent DNA difference. Don't worry if you can't figure out exactly where to put 2.79 or
whatever; put it in approximately the right spot.
