In-class Exercise: Sources of Variation in Populations part of Cutting Edge:Paleontology:Activities
Students identify sources of morphological variation (genetic, ontogenetic, sexual, and ecophenotypic differences) among the individuals of populations for three different species, one of which is colonial.
Introduction to Skeletons part of Cutting Edge:Paleontology:Activities
This lab presents a specimen-based study of the different skeletal systems of animals and plants. The emphasis is on understanding the functional roles mineralized skeletons play in the major skeletonzied phyla comprising the fossil record, how skeletons grow and develop and what biological information they contain. As background for the main topic, students also learn about processes of biomineralization, the coelom as a hydrostatic skeleton and the Cambrian Explosion of skeletal invertebrates at the base of the Cambrian Period..
Introduction to Paleontology part of Cutting Edge:Paleontology:Courses
The course presents an overview of the evolution of our biosphere based on the data of the fossil and molecular records. There is an emphasis on the geological and biological factors that appear to have regulated biodiversity over geologic time. The course emphasizes an understanding biological relationships and processes. This is generally at the expense of detailed systematic (classification-based) treatments of fossil groups.
