摘要: The sequencing of the platypus genome represents a significant milestone in study mammalian evolution. is an egg-laying mammal, member order Monotremata, most divergent clade. It first monotreme to have its sequenced. Its unique evolutionary position, as offshoot between early divergence birds and later emergence therian (eutherian marsupials) mammals, provides unrivalled opportunity understand evolution all mammals. Much like physical characteristics platypus, shows traces amalgamation reptilian traits. Key findings emerge from project include complex sex chromosomes, transition live birth immune genes venom molecules this species.
