Fossil track sites on the Cape south coast show ancient evidence of Knysna elephants

2021-12-21 - Cape Town, South Africa. Charles Helm

In the 19th century, a population that came to be known as the “Knysna elephants” (a reference to the nearest big town) were the most southerly group of elephants in Africa. Over time they became the only free-ranging elephants in South Africa. Their numbers were decimated by the ivory market and habitat transformation. Evidence indicates that only one elephant, an adult female in her forties, remains. Now, about 18km from the area that lone elephant occupies, we have found new evidence of h...

2021-06-23 - Palermo, Italy.

A team of UK and international scientists has confirmed that one of the largest land mammals that ever lived lost 8,000kg to evolve into a now-extinct species of dwarf elephant. In addition, the animal that once lived an isolated existence on the Italian island of Sicily also reduced in height by two metres to create a remarkable transformation.

According to information released by the University of York in the UK, the Sicilian dwarf elephant – thought to have become extinct abo...

First million-year-old DNA extracted from Siberian mammoth teeth

2021-02-17 - Stockholm, Sweden.

For the first time, preserved DNA has been recovered from animal remains over a million years old. The DNA belonged to two mammoths that lived around 1.2 million years ago. “Instead of there being one species [or lineage] of mammoth up in Siberia around 1-2 million years ago, it now looks like there are two,” says Love Dalén at the Centre for Palaeogenetics in Stockholm, Sweden. The genetic sequences change our understanding of mammoth evolution. They reveal that, at that time, Siberia was ...

Why do elephants and tigers still roam in India? Study offers clues

2020-12-08 - Delhi, India.

Tropical Asia and Africa are the only regions on Earth that retain diverse populations of large, land-dwelling mammals, such as elephants, rhinos, and big cats. A new study co-authored by Yale researcher Advait M. Jukar suggests that the persistence of mammalian megafauna in the Indian Subcontinent is related to the great beasts’ long coexistence there with homo sapiens and other human ancestors.

Reviving Extinct Species: Is It Worth the Cost?

Reviving extinct animals like the woolly mammoth could divert funds away from protecting living species, some scientists say.

2017-02-27 - , United States.

A new study of de-extinction — the potential to use genetic techniques to recreate lost animals and plants — finds that given limited conservation dollars, the benefits of bringing back one lost species would probably cost the extinction of more species that are currently on the brink. For example

DNA proves mammoths mated beyond species boundaries

2016-04-23 - Hamilton, Canada.

Several species of mammoth are thought to have roamed across the North American continent. A new study in the open-access journal Frontiers in Ecology and Evolution, provides DNA evidence to show that these mammoths, which should only mate within their species boundaries, were in fact likely to be interbreeding.

Alarm over elephant inbreeding in Sabah

2016-02-26 - Kota Kinabalu , Malaysia.

Experts believe that the state’s 2,500 Bornean elephants were at risk of inbreeding in fragmented areas of its jungles as they are unable to meet elephants from other parts to mate and strengthen their gene pool.

North American Mammoths Actually Evolved in Eurasia

The European mammoth species, Mammuthus meridionalis, likely never made it to North America, a new study finds.

2015-11-13 - London, United Kingdom.

The famous Columbian mammoth — an 11-ton creature known for traversing North America during the last ice age — might actually be the same species as the Eurasian steppe mammoth, said study co-researcher Adrian Lister, a research leader of paleontology at the Natural History Museum in London. The discovery suggests that the first mammoth to enter North America was the Eurasian steppe mammoth, and not its ancestor, a European creature called Mammuthus meridionalis.

The extinct woolly mammoth was as smart as African elephant, says pioneering new brain analysis

The brain of Yuka was very well preserved, and we could compare it to the brain of an African elephant

2015-11-12 - Yakutia, Russian Federation.

Elephants are famed for their intelligence, and now it seems likely that the long-gone woolly mammoths were just as clever. Scientists from Russia and South Africa combined to undertake the first-ever comparison between the brains of the two creatures, using remains of adolescent Yuka, found five years ago close to the Laptev Sea in the Ust-Yansky district of the Sakha Republic, also known as Yakutia.
