Meeting Abstract 69.1  Tuesday, Jan. 6 08:00  On homology of Pancrustacean Compound Eyes OAKLEY, T.H.; Univ. of California, Santa Barbara oakley@lifesci.ucsb.edu Compound eyes are quintessential complex traits, comprised of numerous parts that work together to perform exquisite functions. How and how often does such complexity evolve? One approach to this question is to trace the evolutionary histories […]
