as they were published. There was no textbook because it covered the forefront of research in the field.
In my Biodiversity course we took 6 laboratory practicals (plus other exams) identifying organisms in the entire biological world. It was thousands of specimens. The evolutionary relationships were not only apparent, but undeniable. My professor was a big fan of Lynn Margulis and we covered the endosymbiotic theory quite a bit.
I have similar stories for all of them.
You're anecdote about taking a joke 'biology' class is irrelevant.
Why would you laugh about your ignorance in a field and brag about passing on an opportunity to study it?
Donvino I challenge you to go take some biology courses. Real biology courses designed for pre-meds and future PH.Ds. Go find out for yourself. Take courses like Biodiversity, Comparative Anatomy, Neurobiology, Developmental Biology, Genetics, Molecular Biology, Animal Physiology, and Microbiology. (Also some chemistry and physics so you can truly appreciate how everything ties together).
