Human embryo

Book: This book is required, but you don't need to get the loose leaf version

Course Description: This course will give you some basic understanding about the morphological changes that occur during the development of select animals, as well as the underlying molecular events that produce those morphological changes.

Learning Outcomes: When you have completed this course you will be able to describe, compare, and contrast the events of early development and morphogenesis in some animals. You will be able to give the details of the molecular mechanisms of cell-cell, cell-matrix, and tissue interactions during development. You will be able to explain how the common genetic makeup shared by all cells comprising an organism can be regulated to produce a large variety of cell types, and you will be able to explain how changes in developmental programs result in evolutionary change at the gross morphological level.

Be careful in your reading, if you search for macroevolutionary change. "Macroevolution" is one of the buzzwords used by creationists and searching for this term brings up many creationist websites (e.g. talkorigins and icr=institute for creation research)
