This is odd, since mammals are not on the bird lineage according to Darwinians. The article begins telling a story of how humans lost all 3 of them and replaced them with casein genes, but the platypus lost two of the vitellogenin genes. The press release discusses genes for milk, called vitellogenin genes. It has preserved many of its ancestors’ original features - which probably contribute to its success in adapting to the environment they live in,” says Professor Zhang.Īssertions held together by speculations is not helping. But genetically, it is a mixture of mammals, birds and reptiles. “Indeed, the platypus belongs to the Mammalia class. The platypus belongs to an ancient group of mammals - monotremes - which existed millions of years prior to the emergence of any modern-day mammal. Notice this fur-covered mammal has a duckbill, webbed duck feet and a body with short legs like a Dachshund. We look for demonstrations of evolution, not assertions.įigure 1. First we need to know if the genome answers how platypus features “ emerged” (a magic word till demonstrated). That appears to be an unwarranted extrapolation. Whether it improves understanding of human evolution remains to be seen.

It holds the key as to why we and other eutheria mammals evolved to become animals that give birth to live young instead of egg-laying animals,” explains Professor Guojie Zhang of the Department of Biology. At the same time, decoding the genome for platypus is important for improving our understanding of how other mammals evolved - including us humans. “The complete genome has provided us with the answers to how a few of the platypus’ bizarre features emerged. Their findings are published in Nature, they say we’ll get back to that later. They mapped the platypus genome, which is legitimate work.

They will not give a full account of all the bizarre characteristics just some of them. Now, an international team of researchers led by University of Copenhagen has conducted a unique mapping of the platypus genome and found answers regarding the origins of a few of its stranger features. Often considered the world’s oddest mammal, Australia’s beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes. Anticipating some good scientific work, let us approach the story with an open mind, seriously and respectfully. Here comes the Kipling-form JSS (just-so story): “How the X got its Y.” This will be a test of the explanatory power of Darwinian evolution.

How Earth’s oddest mammal got to be so bizarre ( University of Copenhagen). Has the mystery of platypus evolution been solved since the 2016 Aug 1 attempt?

Its original scientific name Ornithorhynchus paradoxus, “bird-snouted paradox,” (now Ornithorhynchus anatinus) indicated the puzzled looks its 1798 discoverers wore when first looking at it. The platypus looks like a hodgepodge of unrelated animals. They lay eggs instead of bearing live young. The duck-billed platypus and the echidna are the only two members of a group of marsupial mammals called monotremes. It’s been a long time since scientists have tried to Darwinize the platypus.
