The key points from this module are:
Developmental biology is the science that investigates how a variety of interacting processes generate an organism.
Developmental Biology is divided into several categories :
Cellular differentiation
Morphogenesis
Growth
Reproduction
Evolution
Environmental Integration

There are three approaches to Developmental Biology
Anatomical
Experimental
Genetic

Anatomical Approaches are divides in 4 categories
Comparative embryology
Evolutionary embryology
Teratology
Mathematical Modeling

There are three germ layers
Ectoderm: Outermost layer of the embryo
Brain, Nerve cells, the surface layer of sin
Mesoderm: Middle
Heart, blood, kidney, Gonads, Bone
Endoderm: Inner
Intestine, lung
