JAC

JAC is named in loving memory of Professor Jenny Clack, a world-class palaeontologist, widely acknowledged as the leading authority on the evolution of land vertebrates from fish. The name JAC was chosen by Jenny's husband Rob who said "It seemed appropriate I should contribute to this important scientific study of cuckoos in memory of a top-class scientist, whom I adored."
