Early in 2010, on the strength of the Russian translations of his novel "Only Begotten Daughter" (1990) and collection "Bible Stories for Adults" (1996), Morrow was invited to participate in the Fifteenth International Tolstoy Conference. After spending a week in Moscow, he and Kathryn traveled to Tolstoy’s estate, where the author delivered a paper titled, “Charles Darwin Comes to Yasnaya Polyana,” a scholarly thought-experiment spun from Morrow’s "Galápagos Regained", his novel (then in progress) about the coming of the Darwinian worldview.
