DNA and Evolution

We have been looking at the evolution of our common ancestor - the first eukaryotic cell. Earlier this week we did an online activity to review the organelles of a cell. That activity can be found at Mrs. Sliwinski's site in the biology folder - Virtual Cell Tour. Today we are going to look at the role DNA plays in evolution. There are two web based activities that you are going to do to introduce you to this idea. The directions for the activity can by found by CLICKING HERE.

Common Ancestors December 9, 2008

We have spent the last week of class assembling a cladogram of caminacules so that we could begin to understand the process of evolution by looking at lineage and common ancestry. Today we are going to begin to look at our common ancestors and our evolutionary cladogram by starting at the beginning with the evolution of eukaryotic cells.

We will be doing THIS ACTIVITY in the computer lab today.
