Early mammals lived longer      (via sciencedaily.com)     Original source 

What distinguishes the growth and development patterns of early mammals of the Jurassic period? Paleontologists have been able to gauge the lifespan and growth rates of these ancient animals, and even when they reached maturity, by studying growth rings in fossilized tooth roots.

When mammoths roamed Vancouver Island      (via sciencedaily.com)     Original source 

Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.

Elephants on the move: Mapping connections across African landscapes      (via sciencedaily.com)     Original source 

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.

The race to discover biodiversity: 11 new marine species and a new platform for rapid species description      (via sciencedaily.com)     Original source 

A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.

Smallest arm bone in human fossil record sheds light on the dawn of Homo floresiensis      (via sciencedaily.com)     Original source 

A new study reports the discovery of extremely rare early human fossils from the Indonesian island of Flores, including an astonishingly small adult limb bone. Dated to about 700,000 years old, the new findings shed light on the evolution of Homo floresiensis, the so-called 'Hobbits' of Flores whose remains were uncovered in 2003 at Liang Bua cave in the island's west.

Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.

Half a billion-year-old spiny slug reveals the origins of mollusks      (via sciencedaily.com)     Original source 

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).

The ancestor of all modern birds probably had iridescent feathers      (via sciencedaily.com)     Original source 

Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
