“A Study of the Evolution and History of Bile Acids” by Lee R. Hagey, Ph.D.

Note to the reader: The following pages began both as a means to keep track of the various species analyzed, and for writing down my ideas before they drifted away into forgetfulness. It was only after being encouraged to make this data public, that I put these notes into “book-like” form. This rearrangement is far from complete, with many omissions. Should you believe that your favorite species has been short-changed, please do not hesitate to contact me at lhagey@ucsd.edu. I intend to make periodic updates to these pages, adding new species, and additional changes to the text.
