Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.

Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Sediment cores off the Nile mouth reveal insights into the effects and causes of heavy rainfall episodes about 9,000 years ago. That will help to prepare for weather extremes in a changing climate.
A fossil found in the Namib desert has been described as a 2.5-metre long predator that resembled a giant salamander
The egg hatch rate of one shark species may plummet by up to 90 per cent by the end of the century, suggesting that other egg-laying sharks are at risk
Ants are one of the few animals that tend to the injuries of their peers, and now it seems they are also the first non-humans known to perform life-saving amputations
Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.

Ammonites were not in decline before their extinction, scientists have found.

The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic diversity but not to the extent that it can explain their ultimate (and mysterious) extinction.
Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and are being referred to by scientists as 'Pompeii' trilobites due to their remarkable preservation in ash.

Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.

Trilobites are one of the most common fossils we know, but normally only their hard exoskeleton is preserved. Now, researchers have discovered a site that was buried by a Pompeii-style volcanic eruption, leaving the arthropods outlined in exquisite detail
A genetic study of woolly mammoths found on an isolated Arctic island shows they reached a stable population that lasted millennia, so were probably wiped out by a random event rather than inbreeding
Researchers have identified the likeliest timeline of the famous Hellenistic-era Kyrenia shipwreck, discovered and recovered off the north coast of Cyprus in the 1960s.
