Scientists said they have mapped the genetic makeup of the platypus — one of nature's strangest animals with a bill like a duck's, a mammal's fur and snake-like venom.The researchers, whose analysis of the platypus genome was published Thursday in the journal Nature, said it could help explain how mammals, including humans, evolved from reptiles millions of years ago.The platypus is classed as a mammal because it has fur and feeds its young with milk. It flaps a beaver-like tail. But it also has bird and reptile features — a duck-like bill and webbed feet, and lives mostly underwater. Males have venom-filled spurs on their heels."At first glance, the platypus appears as if it was the result of an evolutionary accident," said Francis S. Collins, director of the U.S. National Human Genome Research Institute, which funded the study."But as weird as this animal looks, its genome sequence is priceless for understanding how mammalian biological processes evolved," Collins said in a statement.The research showed the animal's multifaceted features are reflected in its DNA with a mix of genes that crosses different classifications of animals, said Jenny Graves, an Australian National University genomics expert who co-wrote the paper."What we found was the genome, just like the animal, is an amazing amalgam of reptilian and mammal characteristics with quite a few unique platypus characteristics as well," she told the Australian Broadcasting Corp.Scientists believe all mammals evolved from reptiles, and the animals that became platypuses and those that became humans shared an evolutionary path until about 165 million years ago when the platypus branched off.

Unlike other evolving mammals, the platypus retained characteristics of snakes and lizards, including the pain-causing poison that males can use to ward off mating rivals, Graves said.More than 100 scientists from the United States, Australia, Japan and other nations took part in the research, using DNA collected from a female platypus named Glennie.

''And God said unto Noah, make yourself an ark of cypress wood, bring forth with thee every creature eh! You will bring with thee very kind of animal according to its kind, and of every kind of creature that crawls on the ground according to its kind, two from all these will go with you to stay alive and thy shalt map out their Genetic DNA later on for thee ok!?''

I saw one not to long ago at Jenolan Caves swimming in a stream. Even though they sound bizarre with the whole reptilian/mammal business they are actually very cute
