(After reading PZ Myers's post on the matter, I've decided to stop using "weird" to describe the platypus's genome. However, I still think the animal itself can aptly be described as weird.)
Nature reports today that the platypus genome has been sequenced by a large international team (note: subscription needed for full article). Fittingly, it seems that the genome is just as delightfully
weird interesting as the platypus itself - a mixture of mammal genes interspersed with ancestral reptilian and avian sequences, with a bit of novelty thrown in, all of which tells us a great deal about mammalian evolutionary history.
Further study of the genome will certainly add to the uniqueness of the platypus and will be helpful in understanding early mammal evolution. I think it's rather poetic that such a
