I'm collecting this information in case it helps support further development of the notes. What's new? More questions throughout the book. I have an answer key to the previous version of the book please email me if you would like a copy. There's a summary at the end of each chapter. An equation sheet at the front of the book, with each equation linked to where the equation appears later in the book. This release has benefited from numerous people carefully reading over sections. A special thanks to Michael Whitlock who gave me corrections throughout the book. Additional examples, figures, illustrations. Kind of lost track of the new additions during the %#* show that is 2020, but the largest single addition is a new section on multivariate fitness landscapes. An expanded introduction with a section on the eugenics and scientific racism.
