GEOGRAPHIC DISTRIBUTION • Example: Many pouched mammals (marsupials) in Australia • Few placental mammals • ( deer, squirrels)
SIMILARITIES IN STRUCTURE • Homologous structures
SIMILARITIES IN DEVELOPMENT • Similar development in embryos
MOLECULAR BIOLOGY • Similarities in DNA • Same four bases • Some have similar sequence of bases
