Geneticist Francisco J. Ayala's book "Darwin's Gift to Science and Religion" was in my list of recommended reading, but after an investigation found he had sexually harassed both faculty and graduate students, I have removed it from the list. Citing articles written or co-written by Ayala - who prior to this was a highly-respected geneticist - is one thing, but I don't feel comfortable recommending a book he has written in the light of this revelation.
