Dr. Hana Kucera and Dr. David Riddel will be guest speakers via video conferencing in our biology course.  Stay tuned for an opportunity to learn about ecology and evolution from marine educators .  Ask questions and interact with Canada's premiere marine science station.   We will arrange for our video conferencing session in the next two weeks.

Evolution notes - Quiz next tuesday

There will be a Quiz on evolution next tuesday.  We will go over these notes today in detail.

The following notes summarize our lessons in evolution
How evolutionary change occurs

also images from a discussion on
punctuated equilibrium
natural selection
For those of you following along in the Miller and Levine text, this material is covered in chapters 13 and 14.

Quiz will be based on the notes and include multiple choice and short answer.  When you hand this in, there will be an open book portion where you will be expected to identify fossils.  You may use your lab notes for this portion of the quiz.

Fossil Lab

There was a lecture on Geological time, a video on why we ought to be grateful to be related to jawed ancestors, and also box sets of fossils, which, like chocolate boxes, come with a nice legend so you can see which one to sample first.  This lab will take two periods, after which, you will hand in your colour coded geological timeline with your observations of known and unknown fossil specimens.

Fossil stations include:
1.  comparative anatomy of modern and fossil animals:  boxed samples
2.  Wards fossil box (little samples, use the lenses)
3.  unknown sample set, mainly plants,  including a gingko fossil, with some modern gingko for comparison
4.  Texas Cordova Shell limestone, dating back to the cretaceous, and featuring Trigonia, a clam-like shell and turritella, a tightly spiraled snail-like creature.

Draw, observe, place in the correct location on the timeline and hand in wednesday.
