My 2 .- In this course the ability to memorize vast quantities of information will only get you half way there. Whenever possible I will emphasize comprehending concepts, not memorizing facts. You must understand these concepts such that you are able to recognize them in different situations, and apply them in new and unexpected ways. You will be tested on your ability to synthesize, summarize, comprehend and extrapolate, rather than on your ability to memorize.

The lectures will cover the evolutionary history of vertebrates, with particular attention to the evolution of their organ systems. The laboratories will provide you with a comparative perspective of vertebrate anatomy and morphology, and will be integrated with the lectures as much as possible. This course represents a unique chance to examine 400 million years of evolution of familiar but seldom well-known group of animals. The course should lead you to view Homo sapiens in a more realistic perspective, as merely one among many thousands of vertebrates, and certainly not as the pinnacle of creation. Evolution has no pre-ordained aims; the vertebrate lineage just happens to have produced animals with trunks, animals with slimy scales, animals with colourful plumages and animals with big heads.
