A woolly brown rhinoceros that weighed two tons once roamed northeastern Siberia before mysteriously disappearing around 14, years ago. Was its demise caused by humans, or the warming climate of the time? A new study by a Swedish and Russian team of scientists who examined DNA fragments from the remains of 14 of these prehistoric mammals lets our species off the hook. They say the population of the animal – also known by its scientific name Coelodonta antiquitatis – remained stable for millennia as they lived alongside humans, before dropping sharply toward the end of the last ice age. Dalen led the study that was published in the journal Current Biology on Thursday. How did they reach that conclusion from DNA strands taken from the remains of animals frozen in the soil for thousands of years? The size of a population of a species is proportional to its level of genetic diversity and the degree of inbreeding, said Dalen. The team were able to analyze the complete genome of one rhinoceros dating from 18, years ago. By comparing the chromosomes inherited from the mother and from the father, they determined inbreeding was low and diversity was high.

We can be confident in these results because they used several independent dating methods that are all in agreement. Who butchered the rhino?
This exciting new finding, published today in Nature , suggests that early hominins were more widespread than previously thought in Wallacea — the vast network of islands located east of continental Eurasia. The work is published by an international research team, including French, Filipino, Australian and Dutch scientists. Marks on the bones indicate slicing with sharp-edged stone tools, showing that hominins removed flesh and fat from this large animal which they either killed or found recently deceased.
Simple stone tools were found near the rhino. Read more: Ancient stone tools found on Sulawesi, but who made them remains a mystery. The rhino and tools were buried in river sediments. We can be confident in these results because they used several independent dating methods that are all in agreement. Prior research shows that archaic hominins had reached the islands of Sulawesi and Flores to the south of Luzon by at least , years ago and one million years ago, respectively.
Given that archaic hominins were able to colonise Sulawesi and Flores, it stands to reason that they also could have made it to the Philippines — but until now conclusive evidence for this has been lacking. However, the most likely candidate is Homo erectus , a widespread species that inhabited Java from 1. That said, it is now clear that Wallacea is a highly enigmatic region with a complex role in the human evolutionary story, so I would not rule out the possibility that an entirely unknown species inhabited Luzon.
The Luzon team concludes that hominins of some kind had established a presence in the northern Philippines during the Middle Pleistocene epoch between , and , years ago , that they must have come originally from Borneo to the southwest or Taiwan to the north, and that they could potentially have used boats.
World’s last male rhino getting help from Tinder dating app
A rhinoceros dubbed the world’s most eligible bachelor is debuting on Tinder, and a swipe right could help save his species. Ol Pejeta Conservancy in Kenya partnered with dating app Tinder to launch a campaign to raise awareness about the rhino, named Sudan, who the conservancy says is the only remaining male northern white rhino in the world. Matt David, Tinder’s head of communications and marketing, says he is optimistic Sudan’s profile will be seen on Tinder in countries and over 40 languages.

The life he lived: Photos of the last male northern white rhino
A fisherman in a kayak works the waters below Ford Dam on the Mississippi River. Just two animals remain, and both are female. The viable embryo is just the third to be created in a lab with eggs taken from the females and inseminated with frozen sperm from dead males, according to Wednesday’s statement. The embryos are stored in liquid nitrogen to be transferred into a surrogate mother — a southern white rhino — in the coming months.
The ultimate goal is to create a herd of at least five animals that could be returned to their natural habitat in Africa. That could take decades.

Many scientists had assumed that the woolly rhinoceros, a shaggy beast that sported an enormous horn, suffered the same fate. The animal was common in northern Europe and northern Asia 30, years ago, when the first humans arrived. Shortly after, it disappeared. In a paper published in Current Biology , they use data from ancient DNA to argue that, this time at least, humans might be innocent. Until recently, information on the fate of the great ice-age mammals had been limited to what could be gleaned from fossilised bones.
While useful, bones can only tell you so much. They can reveal the number of animals of different ages present at a specific location at a specific time. With some species sex can be determined. Occasionally the cause of death can be detected. In the past couple of decades, though, scientists have learned to tap another, richer source of information: ancient genomes.
By itself, DNA degrades quickly, attacked by water and sunlight. But DNA encased within bones and teeth can survive for longer, especially if those bones and teeth are themselves encased in permafrost. Working with a team of colleagues, the researchers obtained DNA from 12 woolly-rhinoceros bones collected from permafrost in Siberia, dating from the beginning of the Late Pleistocene, about , years ago, until the animals were on the verge of extinction. Extra DNA was recovered from one sample of rhino hair and one piece of tissue found in the stomach of a frozen wolf that had been preserved by the cold.

The year-old rhino named Sudan, listed as “The Most Eligible Bachelor in the World” on the Tinder dating app last year as a fundraiser, lives.
Nairobi, Kenya: There’s just one male northern white rhino left in the world, and he’s getting some help from the Tinder dating app. A Kenyan wildlife conservancy is teaming up with Tinder for a campaign called “The Most Eligible Bachelor in the World,” focusing on the rhino named Sudan. They are raising money for research to save the species from extinction. The year-old Sudan and his last two female companions are unable to breed naturally because of issues that include old age.
