Its hilarious that you creationists smugly bring up the platypus so often, as if it strikes a blow against evil evolution. In fact, it supports the theory that mammals evolved from reptiles, because it is a mammal with reptilian traits. This is evidenced even at the DNA level.
Because of the early divergence from the therian mammals and the low numbers of extant monotreme species, the platypus is a frequent subject of research in evolutionary biology. In 2004, researchers at the Australian National University discovered the platypus has ten sex chromosomes, compared with two (XY) in most other mammals (for instance, a male platypus is always XYXYXYXYXY),[66] although given the XY designation of mammals, the sex chromosomes of the platypus are more similar to the ZZ/ZW sex chromosomes found in birds.[67] The platypus genome also has both reptilian and mammalian genes associated with egg fertilisation.[35][68] Since the platypus lacks the mammalian sex-determining gene SRY, the mechanism of sex determination remains unknown.[69] A draft version of the platypus genome sequence was published in Nature on 8 May 2008, revealing both reptilian and mammalian elements, as well as two genes found previously only in birds, amphibians, and fish. More than 80% of the platypus' genes are common to the other mammals whose genomes have been sequenced.[35]Platypus - Wikipedia, the free encyclopedia
Yes this is funny. They scream for a missing link and then when they have one they complain because it does not fit nicely into either box.
