DEVO@CU is an attempt to build a coherent introduction to the key ideas, observations, and model systems used in the study of developmental biology. 

DEVO is part of a larger curricular redesign effort that includes biofundamentals, CLUE: Chemistry, life, the universe & everything & Organic CLUE (O!CLUE)(testimonial).
