Demise of Australia\u2019s large kangaroos likely not caused by climate change, study suggests<\/strong><\/p>\n\n\n\n

ADELAIDE, Australia \u2013<\/strong> A new study has shed light on the extinction of many of Australia<\/a>\u2019s prehistoric kangaroos, challenging beliefs that their demise was closely linked to climate change.<\/p>\n\n\n\n

In university research published in the journal Science<\/a>, researchers said they used dental analysis to determine feeding habits, which turned out to differ from previous assumptions.<\/p>\n\n\n\n

Wildlife biologists had assumed that climate change transformed ecosystems in ways the giant mammals couldn\u2019t adapt to, but dental analysis now suggests these animals were actually able to adjust to the changing environment.<\/p>\n\n\n\n

\u2026<\/p>\n\n\n\n

\u201cOur study shows that most prehistoric kangaroos at Naracoorte had broad diets. This dietary flexibility likely played a key role in their resilience during past changes in climate<\/a>,\u201d Dr. Samuel Arman, one of the lead researchers on the project, told staff at Flinders University in Australia.<\/p>\n\n\n\n

So, what caused many of the continent\u2019s large kangaroos to go extinct?<\/p>\n\n\n\n

Researchers suggested the arrival of humans played a more significant role than previously thought more than 40,000 years ago.<\/strong><\/p>\n\n\n\n

Hunters primarily used the animals for their meat, with their skins turned into leather and other materials.<\/strong><\/p>\n\n\n\n

Dietary breadth in kangaroos facilitated resilience to Quaternary climatic variations<\/strong><\/p>\n\n\n\n

Editor\u2019s summary<\/strong><\/p>\n\n\n\n

Much can be said about what a species ate based on the form of their teeth. In Australia, it has been hypothesized that the extinction of many large marsupial species by about 40,000 years ago may have been due to a narrow diet in the face of a changing climate. Arman et al<\/em>. looked at extant and extinct kangaroo species using a tooth microwear approach and concluded that most species were generalists, not specialist grazers or browsers, and thus were adapted to deal with climate-driven vegetation changes. Thus, their demise was likely not driven by climate change, leaving humans as the probable cause. \u2014Sacha Vignieri<\/p>\n\n\n\n

Abstract<\/strong><\/p>\n\n\n\n

Identifying what drove the late Pleistocene megafaunal extinctions on the continents remains one of the most contested topics in historical science. This is especially so in Australia, which lost 90% of its large species by 40,000 years ago, more than half of them kangaroos. Determining causation has been obstructed by a poor understanding of their ecology. Using dental microwear texture analysis, we show that most members of Australia\u2019s richest Pleistocene kangaroo assemblage had diets that were much more generalized than their craniodental anatomy implies. Mixed feeding across most kangaroos pinpoints dietary breadth as a key behavioral adaptation to climate-driven fluctuations in vegetation structure, dispelling the likelihood that late Pleistocene climatic variation was a primary driver of their disappearance.

The varied diet argument seems pretty conclusive \u2013 an animal which could adapt its diet to changed conditions would be resilient to changes in conditions.<\/p>\n\n\n\n

Reading the Wikipedia description<\/a>, Procoptodon was likely slow moving compared to modern kangaroos, more of a lumberer than a hopper. Easy prey for early humans with sharp sticks.<\/p>\n\n\n\n
