The goal of this course is to understand plant diversity
from an historical and phylogenetic perspective. Both neobotanical and paleobotanical
data are brought to bear on the analysis of significant evolutionary events/processes
in the history of photosynthetic life. Information from cell biology, morphology,
life history theory, and development are all incorporated into the discussion
of these most significant evolutionary events. Topics covered include the origin
of photosynthetic life, the origin and diversification of eukaryotes, the colonization
of land by plants, the evolution of roots, leaves and arborescence as a cause
of the great Paleozoic CO2 drawdown (90%), the origin of the seed habit, and
Darwin's "abominable mystery," the origin of flowering plants.
The concepts and information from class are applied to a hands-on set of laboratory sessions in which students study plant diversity. Labs range from an examination of the diverstiy of cyanobacteria to the preparation of fossil peels from Carboniferous coal balls. The goal of every lab is to insure that students experience and interact with the actual data that are the basis for the interpretation of evolutionary history and diversification. |
