Document Summary
Asks why the body is not better designed - extraordinary is some ways while also flawed in others, all with an evolutionary purpose. Define proximate and ultimate causes of disease and provide examples. Proximate: addresses how things work by describing the function of a trait, its anatomy, physiology, biochemistry and development from embryonic form to adult form. Taste buds = describe their structure, the composition of the tissue, chemical reactions that happen when tasting something. Ultimate: addresses why certain things came to be or operate the way they do. Ultimate reason humans have evolved a specific trait in the first place or why we have dna that encode for a certain kind of structure and not another. Taste buds = asks the question what would disadvantages be from not having taste buds, what ancestral structures (if any) were slowly shaped to give taste buds their present form.
