오리너구리는 진화론적으로 매우 학술적 가치가 높은 동물로
알을 낳고 부화하면 젖을 먹이는 포유동물입니다.
아래는 위키피디아에서 부분 발췌한 오리너구리 관련 글입니다
----------------------------------------------------
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),[64] 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.[65] The platypus genome also has both reptilian and mammalian genes associated with egg fertilisation.[34][66] Since the platypus lacks the mammalian sex-determining gene SRY, the mechanism of sex determination remains unknown.[67] 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.[34]

대강 살펴보면 오리너구리의 성염색체 (sex chromosomes)는 조류에 가깝다 할 수 있고,
알을 낳는 것에 관해서는 관해서는 파충류와 포유류의 유전자를 가지고있으며
유전자(genes)의 80% 이상이 포유류이지만
아직까지 새, 양서류, 어류에서만 발견된 두개의 유전자를 가지고 있다고 하네요.
창조론자 입장에서 오리너구리는 신의 실수 같을 겁니다.
