platypus evolution tree

The semi-aquatic monotreme is a venomous, duck-billed mammal that lays eggs, nurses its young and occupies a lonely twig at the end of a sparse branch of the vertebrate evolutionary tree. In the mid-1990s in Tasmania, 40% of platypus deaths were due to attacks by domestic dogs (Connolly et al. 2010; Marchant and Grant 2015). Platypuses do not have teeth, so the bits of gravel help them to "chew" their meal. From the minds that brought you Cow Evolution and forever changed the way you see bovines, comes a new game that somehow manages to be even crazier and more nonsensical. 2001; Fish et al. Spatial-organization and movement patterns of adult male platypus. Bethge, P., S. Munks, H. Otley, and S. Nicol. Yes, platypus are already odd by nature. Blood oxygen levels fall rapidly during diving, with rapid restoration of arterial O2 saturation following dives (Johansen et al. Respiratory properties of blood and responses to diving of the platypus, Mechanistic niche modelling: combining physiological and spatial data to predict species’ ranges, Australian Journal of Experimental Biology and Medical Science, Better smelling through genetics: mammalian odor perception, Habitat loss and landscape degradation: the disastrous outlook for vertebrate fauna in central western NSW, Ecological impacts of dams, water diversions and river management on floodplain wetlands in Australia, Major conservation policy issues for biodiversity in Oceania, Platypus in a changing world: impacts of land use and climate, Trophic relationships of the platypus: insights from stable isotope and cheek pouch dietary analyses, Early response of the platypus to climate warming, Platypus venom: source of novel compounds, The history and relationships of northern platypus (Ornithorhynchus anatinus) populations: a molecular approach, Ph.D. thesis, James Cook University, Townsville, Australia, Regional population structuring and conservation units in the platypus (, Brunner’s glands of the duckbilled platypus (, What can monotremes tell us about brain evolution, Philosophical Transactions of the Royal Society B, Husbandry, diet and behaviour of platypus, The tectonic history of Drake Passage and its possible impacts on global climate, Aquatic versus terrestrial insects: real or presumed differences in population dynamics. comm., 2018), suggesting more directed efforts are needed to understand breeding requirements, including habitat and mate selection. Rich, T., P. Vickers-Rich, A. Constantine, T. Flannery, L. Kool, and N. Van Klaveren. 1998; Otley et al. 2014) were not recaptured after their first year, suggesting high dispersal or mortality (Bino et al. Taken together (Fig. 2001). Water resource development, including the building of dams, extraction of water, and development of floodplains, has caused widespread degradation of freshwater habitats within the platypus’ range (Kingsford 2000; Grant and Fanning 2007). 1). When he is all alone, a beam of light raises him into the sky. A dreamtime story of the platypus from the upper reaches of the Darling River (McKay et al. 2016). 1987; Iggo et al. (Also see "Venomous Primate Discovered in Borneo."). B) Dentition of O. dicksoni (upper two rows) and Obdurodon insignis (bottom row—Archer et al. 2010), consuming most invertebrates of a reasonable size, according to availability (Faragher et al. Home ranges vary spatially and temporally with breeding season, age, and sex (Grant et al. 2009), the location of that split is difficult to pinpoint. The platypus is among the most peculiar animals the world has ever seen. 2013; Ornithorhynchus artwork by Rod Scott, Australian Geographic Magazine). Platypuses are amphibious, inhabiting creeks, rivers, shallow lakes, wetlands, and their riparian margins, in agricultural land, urban areas, and natural environments (Connolly et al. 2009; Gust and Griffiths 2011). Our understanding of how threatening processes impact individual health, population dynamics (e.g., survival, dispersal), and habitat quality remains largely qualitative in nature, demanding we develop quantitative models that allow predicting population viabilities, critical for prioritizing conservation management strategies. 2005; Pian et al. 2009). Platypus thumbs its nose (or bill) at evolutionary scientists Recent publication of the platypus genome makes evolution even more problematic. 2008; Phillips et al. In contrast, individuals from New South Wales appear to have had higher and relatively stable genetic diversity through their history. 5), the fossil record of ornithorhynchids provides a disquieting deep-time perspective on the conservation status of the living platypus that suggests that the species may be less environmentally resilient than commonly presumed. 2012; Martin et al. Another incredible adaptation is how they forage for food. The Riversleigh species appears to have lived in pools within cool, temperate, lowland rainforest (Archer et al. Hydrologic connectivity critically maintains the ecological integrity of river systems, mediating transfer of organic and non-organic matter, energy, as well as organisms (Pringle 2003). 2010), though small chironomid species may also be important in the diet (McLachlan-Troup et al. 3). the flippers, the duckbill, the tail, internal features), and look for commanalities with possible ancestors and relatives. Ecosystem management and sustainability, A dangerous idea in action: the hegemony of endangered species legislation and how it hinders biodiversity conservation, Dangerous? McLachlan-Troup, T. A., C. R. Dickman, and T. R. Grant. 2011). This split happened before the evolution of the placenta, Young says, “so in that sense they are somewhere between a lizard and what we think of as a human-like placental mammal,” retaining some reptilian and mammalian features. Nature. Pascual, R., F. J. Goin, L. Balarino, and D. Udrizar Sauthier. Effective conservation of platypus populations hinges on controlling threatening processes, supported by investment in systematic long-term monitoring of trends in population sizes, demographics, distribution, genetics, and diseases. Koh, J. M. S., P. S. Bansal, A. M. Torres, and P. W. Kuchel. 2). High flow events may increase foraging energetics for platypuses (Gust and Handasyde 1995); summer flood events can reduce recruitment (Serena et al. In this synthesis, we review the evolutionary history, genetics, biology, and ecology of this extraordinary mammal and highlight prevailing threats. Dowiedz się, w Platypus Evolution (Ewolucja Dziobaka)! Today, the platypus (Ornithorhynchus anatinus) maintains an even more restricted area, the river systems of eastern Australia (modified after Archer 1995; Steropodon image by Peter Schouten; Monotrematum image by James McKinnon—Archer 1995; Obdurodon image by Peter Schouten—Pian et al. 2018c). Photo by Doug Gimesy. The platypus, along with its fellow monotreme, the echidna, was believed to have evolved in isolation when the land mass that would become Australia (Gondwana) broke away from the other continents supposedly 225 million years ago. 2012; Bino et al. This study was funded by an Australian Research Council Linkage grant LP150100093 and the Marcia Evelyn Williams Bequest, School of Veterinary Science, University of Sydney. 2004; Bethge et al. Accumulating knowledge and technological advancements have provided insights into many aspects of its evolutionary history and biology but have also raised concern about significant knowledge gaps surrounding distribution, population sizes, and trends. 2014). Fyke nets (checked every 2–4 h and allowing unimpeded access to air) are effective in small streams, although capture rates may vary substantially by age, sex, and season, and may also be affected by learned avoidance (Serena and Williams 2012b; Griffiths et al. 1996; Proske et al. Though monotremes' fossil record is limited, some skulls have been found, such as the extinct Obdurodon dicksoni. Thomas, J. L., M. L. Parrott, K. A. Handasyde, and P. Temple-Smith. (Related: "Platypus Genome Reveals Secrets of Mammalian Evolution."). These gaps limit our ability to assess the current status and to develop conservation strategies for safeguarding the future of platypus populations. 1966; Evans et al. 2016). Archer, M., S. J. 2001) begins with a young duck who disregarded her tribe’s warning of Mulloka (or Waaway), the water devil (Pike 1997). Connolly, J. H., T. Claridge, S. M. Cordell, S. Nielsen, and G. J. Dutton. Amato, G., O. Ryder, H. Rosenbaum, and R. DeSalle (eds.). Walsh, C. J., T. D. Fletcher, and M. J. Burns. 2009). A. Webb. 1992), the signal may be amplified by large numbers of receptors in the bill being stimulated at the same time. 2017a). 2017b). 2008; Macgregor et al. The body temperature of the platypus is maintained close to 32°C in air and water, with an ambient temperature tolerance of 0–30°C (Grant and Dawson 1978; Grant 1983; Grant et al. Consequently, Victorian Fisheries Authority announced a state-wide ban on use of enclosed traps from 2019 (VFA 2018). Find out in Platypus Evolution! Mammal-like reptiles diverged from the lineage they shared with birds and reptiles about 280 million years ago. Breeding in a free-ranging population of platypuses, Draft plan of management for the platypus, Ornithorhynchus anatinus, in New South Wales, NSW National Parks and Wildlife Service, Sydney, New South Wales, Australia, Philosophical Transactions of the Royal Society of London B: Biological Sciences, Growth of nestling and juvenile platypuses (. Assessing the reproductive status of females remains reliant on inducing milk let-down using injected synthetic oxytocin (Grant et al. 1992a, 1992b, 2002; Archer et al. Death may also result from secondary bacterial infections or impaired thermoregulation and mobility. 1992; McLeod 1993; Serena 1994; Gardner and Serena 1995; Gust and Handasyde 1995; Serena et al. 2012). Connolly, J., D. Obendorf, R. Whittington, and D. Muir. 2014). The platypus’ distribution coincides with many of Australia’s major threatening processes, including highly regulated and disrupted rivers, intensive habitat destruction, and fragmentation, and they were extensively hunted for their fur until the early 20th century. 2015). A vomeronasal (Jacobson’s) organ inside the front of the upper bill opens into the oral cavity (Griffiths 1978). Monotremes are considered primitive mammals, and platypuses are the remaining members of the family Ornithorhynchidae. Young notes that there is "some randomness to how we acquire things over time," plus mutations and adaptations that happen more quickly. Platypuses hunt underwater, where they swim gracefully by paddling with their front webbed feet and steering with their hind feet and beaverlike tail. Hand, R. M. D. Beck, and A. Cody. Although the spurs and venom may have had a defensive function in evolutionary history, as hypothesized for Mesozoic mammals (Ligabue-Braun et al. The male venom gland may be a derived sweat gland, which enlarges during the breeding season along with increased venom production and male aggressiveness (Temple-Smith 1973). 2015). Distribution of the platypus coincides with major threatening processes (Kingsford et al. Given records of skin sales account for 10–100% of current population estimates (30,000–300,000—Woinarski and Burbidge 2016) and the slow reproductive rate of platypuses (1.5 young per year, with only half of females breeding in a given year—Bino et al. 2016). © 1996-2015 National Geographic Society, © 2015- River regulation alters the natural flow regime including both magnitude and frequency of flow events, degrading the ecological health of impacted river sections (Gilligan and Williams 2008). Although the electric field strengths of common prey species are not within the range detectable by the electroreceptors (Taylor et al. 1992; Serena 1994; Gardner and Serena 1995; Gust and Handasyde 1995; Serena et al. Dives have an aerobic limit of 40–59 s (Bethge et al. Koch, N., S. Munks, M. Utesch, P. Davies, and P. McIntosh. Unfortunately, because of a lack of fossil tachyglossids more plesiomorphic than the extant long-beaked (Zaglossus spp.) "Top billing for platypus at end of evolution tree Monotreme's genome shares features with mammals, birds and reptiles. During courtship, female and male platypuses engage in a dance, during which the male holds the tail of the female with his bill, and the female leads them both through a series of slow circles, twists, and turns on the surface of the water, followed by mating (Holland and Jackson 2002; Hawkins and Battaglia 2009; Thomas et al. 2004). 2001; Munks et al. The underfur retains air during dives, providing efficient insulation against heat loss, which is aided by a counter-current heat exchange in the cardiovascular system supplying the bare extremities (Grant and Dawson 1978). Relatively little attention has been paid to biofluorescence in Australia's animals. 2017b). 2018b), but is much higher (90–100%) in lactating females (Holland and Jackson 2002), suggesting increased energy expenditure. Altering the natural flow regime can impact resources required by platypuses, as well as reproduction (Serena and Grant 2017). As the sun sets, Buck and Chuck decide to go home before it gets dark. 2008; Martin et al. Platypuses show bradycardia on submersion, from a normal heart rate of 140–230 beats per minute (BPM) to 10–120 BPM. Bino, G., R. T. Kingsford, T. Grant, M. D. Taylor, and L. Vogelnest. Martin, E. H., C. J. Walsh, M. Serena, and J. Thomas, J., K. Handasyde, M. L. Parrott, and P. Temple-Smith. Haematology and blood chemistry of the free-living platypus, Novel venom gene discovery in the platypus, A viral infection causing cytomegalic inclusion disease in the renal epithelium of the platypus (, Serological responses against the pathogenic dimorphic fungus, Age-related change in spurs and spur sheaths of the platypus (, Proteomics and deep sequencing comparison of seasonally active venom glands in the platypus reveals novel venom peptides and distinct expression profiles, The first Tertiary monotreme from Australia, Comparative retinal morphology of the platypus. 2009). This review began with a conference and workshop at Taronga Zoo that brought together many of Australia’s platypus researchers to discuss the current status and challenges for this unique species. In deep pools (> 2 m), unweighted mesh nets, often set an hour before dark, require continuous monitoring to ensure the welfare of platypuses and non-target species (e.g., fish). 1992; Serena 1994; Gardner and Serena 1995; Gust and Handasyde 1995; Otley 1996; Serena et al. A product of Tapps Games. 2010). Overall, the record appears to be one of continuous geographic and taxonomic decline with representatives disappearing from Patagonia within the last 60 million years and from most of mainland Australia, apart from the relatively well-watered eastern coast, within approximately the last 15 million years (Fig. 2000; Temple-Smith and Grant 2001; Grant et al. Despite this increasing research effort, key knowledge gaps remain, particularly with regards to the species’ past and present distribution and numbers, and the impacts of threatening processes on population viability. Current and historical occurrence of platypuses. Gilad Bino, Richard T Kingsford, Michael Archer, Joanne H Connolly, Jenna Day, Kimberly Dias, David Goldney, Jaime Gongora, Tom Grant, Josh Griffiths, Tahneal Hawke, Melissa Klamt, Daniel Lunney, Luis Mijangos, Sarah Munks, William Sherwin, Melody Serena, Peter Temple-Smith, Jessica Thomas, Geoff Williams, Camilla Whittington, The platypus: evolutionary history, biology, and an uncertain future, Journal of Mammalogy, Volume 100, Issue 2, 24 April 2019, Pages 308–327, In 1985, teeth and a nearly complete skull (Fig. A single rug or garment needed more than 50 platypus skins (75 platypus skins were used for a rug on display at the Australian Museum), making their skins more valuable than any other Australian animal (Goulburn Herald 1905). An appropriate level of listing for the platypus on State and Federal threatened species schedules (e.g., Environment Protection and Biodiversity Conservation Act 1999) is also needed based on improved understanding of distributional patterns and demographic processes, focused research, and management of the many threats raised in this review. 2018a). Delineating the thermal tolerance of the species is needed to better predict the impacts of increasing temperatures (Kearney and Porter 2009). Extended droughts can dry up creeks, likely reducing the extent of critical refugia, forcing platypuses to move overland where risk of predation is high, and exacerbating competition within decreasing numbers of pools. 2014), indicating platypuses are impacted by the altered flow regimes of urban streams. Platypus' evolutionary roots are highly controversial. 2018). Juvenile males have been found to travel greater distances (Bino et al. The first breakthrough came with discovery of two well-formed teeth in Oligocene (~26 Mya) clay deposits in central South Australia (Fig. Money is made by platypuses, being their poop. The venom has a chemically complex composition (de Plater et al. 2013). Egg-laying, duck-billed, beaver-tailed, otter footed mammals... And venomous! The oldest estimate suggests this split may have occurred during the mid-Cretaceous (~80–100 Mya—Musser 2003). 1993). 1992; McLeod 1993; Serena 1994; Gardner and Serena 1995; Gust and Handasyde 1995; Serena et al. Like all mammals, the platypus as a single lower jaw bone and three middle ear bones. Grant, T. R., G. C. Grigg, L. A. In a subalpine Tasmanian lake, radiotagged individuals occupied areas of 2–58 ha over periods of 22–90 days (Otley et al. Health assessments include external physical examination, collection of parasites, sampling excreta for reproductive hormones, corticosteroid analysis or pathogens, and sampling blood for hematology, serum biochemistry, and serology (e.g., Mucor enzyme-linked immunosorbent assay [ELISA], Leptospira serovar antibody titers—Connolly et al. In turn, runoff has increased dramatically, adding to soil loss and in-channel sedimentation (Walker et al. Mark–recapture methods that take into account detection probabilities can produce robust estimates of population size (Bino et al. Following the introduction of trout species, the use of nets or traps in headwater streams was banned in New South Wales in 1902, providing some protection to platypuses in these regions (Grant 1993). Longitudinal rows of these electroreceptors, and uniformly distributed mechanoreceptors, provide electric and tactile senses, presumed to allow platypuses to navigate and locate weak electric fields produced by macroinvertebrate prey species (Scheich et al. Clearing, grazing, and watering access by livestock have severely degraded river banks and riparian vegetation (Lunney et al. Given that O. agilis DeVis, which is a junior synonym of O. anatinus, is known to have existed in the middle Pliocene at ~3.8 Mya, the possibility cannot be excluded that other events of divergence may have occurred at some point that genetic studies of modern specimens are unable to shed light on. Torres, A. M., D. Alewood, P. F. Alewood, C. H. Gallagher, and P. W. Kuchel. A. M. Graves. 2004). 2009) produced by 88 toxin genes (Whittington et al. Some were also exported to London, although many more were undoubtedly smuggled, disguised as other small mammal skins (Burrell 1927). 1985; Flannery et al. Furthermore, it was possible to establish the relatedness among 28 of the individuals from the same river system and estimate a de novo mutation rate of 4.1 × 10−9–1.2 × 10−8/bp/generation, considered intermediate for a mammal, lower than humans and chimpanzees but higher than laboratory mice (Martin et al. Both the oesophagus and presumptive stomach are small, thin-walled, and lined with non-keratinizing stratified squamous epithelium. Manger, P. R., L. S. Hall, and J. D. Pettigrew. But why platypuses “stopped evolving and losing these components that make a mammal a mammal,” remains a mystery, says Warren. 1995; de Plater 1998; Torres et al. What would happen if mutations started happening to them? 4A and 4B) of a species named Obdurodon dicksoni were discovered in Middle Miocene freshwater limestones (~15 Mya) in the Riversleigh World Heritage Area, Queensland (Lester and Archer 1986; Archer et al. Despite sweat glands in the skin, platypuses are not able to withstand environmental temperatures exceeding 30°C (Robinson 1954); its crepuscular and nocturnal activities and burrow use during the day are likely strategies to avoid extreme heat (Grant and Dawson 1978; Bethge et al. E) Three views of a lower right dentary fragment with RM1-3 of Kollikodon ritchiei. However, there are counter arguments that Ornithorhynchidae may well be paraphyletic, with tachyglossids having evolved from ancestral ornithorhynchids sometime during the Cenozoic (Pascual et al. Newly emerged juvenile platypuses are 65–70% of their adult mass and 83–87% of their adult length (Grant and Temple-Smith 1998b). Mucormycosis was accidentally introduced to toads and frogs on the Australian mainland (Northern Territory, Queensland, New South Wales) by captive frogs from Melbourne and Perth, but the infection has not been recorded in mainland platypuses. Gastric glands and the genes involved in gastric function are absent, and there is therefore no acid secreted and peptic digestion, but Brunner’s glands are present at the end of the stomach (Krause 1971). Observations of the platypus in the wild suggest acute eyesight, especially sensitive to movement (Burrell 1927). Synergistic impacts of habitat destruction and barriers, along with forecasted increasing frequency and intensity of droughts due to climate change that will reduce thermally suitable habitat (Klamt et al. The odd Australian mammal has an intriguing family tree. 2013). Current projections predict both drought frequencies and severity are likely to increase (CSIRO and Bureau of Meteorology 2015), further threatening small and isolated populations. Australian National Parks and Wildlife Service by Mt. 4C) from Paleocene deposits (63–61 Mya) in Argentina, it became clear that platypuses formerly existed on a continent that is now far beyond Australia (Fig. By-catch mortality in fishing gear (Grant and Fanning 2007; Serena and Williams 2010a), diseases, and predation by invasive foxes and feral dogs (Serena 1994; Connolly and Obendorf 1998; Grant and Fanning 2007) also impact platypus populations.
