25 lut 2021 · Researchers interested in exploring what makes monotremes unique have two new genetic resources to work with: an improved reference genome for the platypus Ornithorhynchus anatinus, filled in...
16 mar 2022 · Advances in dating and systematics have prompted a revision of monotreme evolution to refine the timing of adaptative trends affecting body size and craniodental morphology. The oldest known...
28 mar 2022 · Monotremes are iconic Australasian species. But the origins of these species have continually raised questions for scientists; why aren’t they more present in the fossil record and why can we only find them in Australia and New Guinea?
21 lis 2015 · Particular attention is given to a recent paradigm shift on monotreme evolution, with the latest research suggesting that monotremes are part of an ancient, Gondwanan radiation of mammals...
Professor Flannery said the research reveals that 100 million years ago, Australia was home to a diversity of monotremes, of which the platypus and the echidna are the only surviving descendants. “Today, Australia is known as a land of marsupials, but discovering these new fossils is the first indication that
1 gru 2003 · Within the last 40 years, more and more details of monotreme physiology, histology, reproduction and genetics have been revealed. Some show similarities with birds or reptiles, some with therian mammals, but many are very specific to monotremes. The genome is no exception to monotreme uniqueness.
28 mar 2022 · The only living egg-laying mammals, these weird and wonderful animals – the echidna and platypus, now found only in Australia and New Guinea – are the last survivors of a diverse set of fossil species that once roamed the southern continents.
