We have no complete skeleton of the ancient megalodon shark, but new evidence points to it being more long and slender than previous depictions, say researchers
For primates, being born with a missing limb or experiencing a major injury isn’t necessarily disabling if their environment or social connections help them thrive – just like humans
An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
The new theoretical research proposes that animal size over time depends on two key ecological factors.

Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.

When tardigrades encounter harsh environments, high levels of free radicals in their cells trigger the onset of a dormant state in which they can endure extreme hardship
New Year, new tree? You can ignore advice to stake out your sapling – and get better results in the process, says James Wong

Researchers estimate that 17,000 baby elephant seals have died from avian flu in Argentina and it is likely that the virus is spreading among marine mammals
On hot days, Alpine ibex increase their activity at nighttime to avoid the heat – but this might increase the risk of predation by wolves
Fossils of kelp along the Pacific Coast are rare. Until now, the oldest fossil dated from 14 million years ago, leading to the view that today's denizens of the kelp forest -- marine mammals, urchins, sea birds -- coevolved with kelp. A recent amateur discovery pushes back the origin of kelp to 32 million years ago, long before these creatures appeared. A new analysis suggests the first kelp grazers were extinct, hippo-like animals called desmostylians.

A feeding method of the extinct jawless heterostracans, among the oldest of vertebrates, has been examined and dismissed by scientists, using fresh techniques.
A healthy rhesus monkey has been born after being cloned from fetal cells, but creating a clone of an adult human being would be much harder

New research has precisely dated some of the oldest fossils of complex multicellular life in the world, helping to track a pivotal moment in the history of Earth when the seas began teeming with new lifeforms -- after four billion years of containing only single-celled microbes.
