Which environments did ancient Aboriginal peoples forage in Australia’s Western Desert?

Habitat suitability model. Excavated rockshelter sites with long archaeological sequences (lime green) include: (1) Karnatukul (Serpent’s Glen), (2) Bushturkey-3, (3) Kaalpi, (4) Puntuntjarpa, (5) Parnkupirti, (6) Puritjarra, (7) Glen Thirsty, (8) Tjungkupu, and (9) Kulpi Mara.

Scientists have used more than two decades of satellite-derived environmental data to suggest the possible foraging habitats of pre-contact Aboriginal peoples living in the Western Desert.

Don’t focus on genetic diversity to save our species

Once found throughout the semi-arid range country in South Australia, New South Wales and south-west Queensland, the yellow-footed rock wallaby is now endangered in Queensland and NSW and vulnerable in SA. Image by Philip Barrington from Pixabay.

Scientists have challenged the common assumption that genetic diversity of a species is a key indicator of extinction risk.

Ancient DNA research reveals evolutionary secrets of Game of Thrones dire wolves

Artwork credit: Mauricio Antón/Nature. Caption: Somewhere in Southwestern North America during the late Pleistocene, a pack of dire wolves (Canis dirus) are feeding on their bison kill, while a pair of grey wolves (Canis lupus) approach in the hopes of scavenging. One of the dire wolves rushes in to confront the grey wolves, and their confrontation allows a comparison of the bigger, larger-headed and reddish-brown dire wolf with its smaller, grey relative.

University of Adelaide scientists have sequenced the ancient DNA of dire wolf fossils for the first time and uncovered new secrets of the animal made famous by the TV show Game of Thrones.
