Newly recovered DNA shows the predators share little genetic ancestry with domestic dogs and are descended from ancient animals from China

Scientists have for the first time recovered DNA from the remains of dingoes between 400 and 2,700 years old to find the predator’s population was well established across the Australian continent thousands of years ago.

According to the researchers, modern dingoes share little genetic ancestry with domestic dogs introduced into Australia from Europe but are instead descended from ancient dogs and wolves from China and the Tibetan plateau. Dingoes were closely related to modern New Guinea singing dogs, the research confirmed, with both sharing a common ancestor.

Code will remove grey area around stem cell-based technology and ensure responsible research, say scientists

Biological models of human embryos that can develop heartbeats, spinal cords and other distinctive features will be governed by a code of practice in Britain to ensure that researchers work on them responsibly.

Made from stem cells, they mimic, to a greater or less extent, the biological processes at work in real embryos. By growing them in the laboratory, scientists hope to learn more about how human embryos develop and respond to their environment, questions that would be impossible to answer with real embryos donated for research.

About 2.5 metres long, creature was an apex predator 280m years ago, before age of dinosaurs, say scientists

A giant 280m-year-old salamander-like creature that was an apex predator before the age of the dinosaurs has been discovered by fossil hunters in Namibia.

The creature, Gaiasia jennyae, was about 2.5 metres long, had an enormous toilet seat-shaped head and fearsome interlocking fangs. It lurked in cold swampy waters and lakes with its mouth wide open, preparing to clamp down its powerful jaws on any prey unwise enough to swim past.

Discovery of ‘echidnapus’ and two more species show the furry egg-layers predated marsupials

Some time about 100m years ago in what is now an Australian opal field, a weird, furry, egg-laying, rabbit-sized mammal was gliding through a waterhole across a massive polar floodplain.

This mammal – Opalius splendens but which scientists have thankfully blessed with the nickname “echidnapus” – was among the ancient descendants of one of the planet’s most unique orders of animals, the monotremes.

Experts believe remains belong to a type of ichthyosaur that roamed the seas about 202m years ago

Fossils discovered by an 11-year-old girl on a beach in Somerset may have come from the largest marine reptile ever to have lived, according to experts.

The fossils are thought to be from a type of ichthyosaur, a prehistoric marine reptile that lived in the time of dinosaurs. The newly discovered species is believed to have roamed the seas towards the end of the Triassic, about 202m years ago.

The French aristocrat who understood evolution 100 years before Darwin – and even worried about climate change

Georges-Louis Leclerc proposed species change and extinction back in the 1740s, a new book reveals

Shortly after Charles Darwin published his magnum opus, The Origin of Species, in 1859 he started reading a little-known 100-year-old work by a wealthy French aristocrat.

Its contents were quite a surprise. “Whole pages [of his book] are laughably like mine,” Darwin wrote to a friend. “It is surprising how candid it makes one to see one’s view in another man’s words.”

In later editions of The Origin of Species, Darwin acknowledged Georges-Louis Leclerc, Comte de Buffon, as one of the “few” people who had understood that species change and evolve, before Darwin himself.

Fossil of giant river dolphin found in Peru, whose closest living relation is in South Asia, gives clues to future extinction threats

Scientists have discovered the fossilised skull of a giant river dolphin, from a species thought to have fled the ocean and sought refuge in Peru’s Amazonian rivers 16m years ago. The extinct species would have measured up to 3.5 metres long, making it the largest river dolphin ever found.

The discovery of this new species, Pebanista yacuruna, highlights the looming risks to the world’s remaining river dolphins, all of which face similar extinction threats in the next 20 to 40 years, according to the lead author of new research published in Science Advances today. Aldo Benites-Palomino said it belonged to the Platanistoidea family of dolphins commonly found in oceans between 24m and 16m years ago.

Discovery was made after First Nations tipped off ecologists about groups of fish gathering in a fjord off British Columbia

Deep in the hostile waters off Canada’s west coast, in a narrow channel surrounded by fjords, lies a coral reef that scientists believe “shouldn’t exist”. The reef is the northernmost ever discovered in the Pacific Ocean and offers researchers a new glimpse into the resilience – and unpredictability – of the deep-sea ecosystems.

For generations, members of the Kitasoo Xai’xais and Heiltsuk First Nations, two communities off the Central Coast region of British Columbia, had noticed large groups of rockfish congregating in a fjord system.
