Question
You are a substitute teacher in a high school biology lab class on the day the students are dissecting fetal pigs. One student finds that his pig's lungs, liver, pancreas, and digestive organs are either missing or small and malformed. The student scratches his head with his clean hand and says, "What went on here?" Although there may be more than one reason, what might you propose as an explanation based on embryonic development?
