I am a student of the arts and am currently putting together a thesis for my final paper, which may be around 8 pages. Our subject has to relate to Darwin. After reading On the Origin of Species I found that it was Darwin who first scientifically observed albinism. In his journal, he suggested that melanin may affect development, not only pigment. He also made the connection between albino cats and deafness. Local libraries and online and college databases seen to offer me NOTHING. Here is what I need: Any and all information on Darwin connecting to albinism. Offer sources. Thank you all so much! I really need the help, and soon.
