Neanderthals ate mussels, fish, and seals too

Over 80,000 years ago, Neanderthals fed themselves on mussels, fish and other marine life. The first evidence has been found by an international team in the cave of Figueira Brava in Portugal. The excavated layers date from 86,000 to 106,000 years ago, the period when Neanderthals settled in Europe. Sourcing food from the sea at that time had only been attributed to anatomically modern humans in Africa.

In Earth's largest extinction, land animal die-offs began long before marine extinction

Because of poor dates for land fossils laid down before and after the mass extinction at the end of the Permian, paleontologists assumed that the terrestrial extinctions from Gondwana occurred at the same time as the better-documented marine extinctions. But a new study provides more precise dates for South African fossils and points to a long, perhaps 400,000-year period of extinction on land before the rapid marine extinction 252 million years ago.

As the ocean warms, marine species relocate toward the poles

Since pre-industrial times, the world's oceans have warmed by an average of one degree Celsius (1°C). Now researchers report that those rising temperatures have led to widespread changes in the population sizes of marine species. The researchers found a general pattern of species having increasing numbers on their poleward sides and losses toward the equator.

Ancestor of all animals identified in Australian fossils

Geologists have discovered the first ancestor on the family tree that contains most animals today, including humans. The wormlike creature, Ikaria wariootia, is the earliest bilaterian, or organism with a front and back, two symmetrical sides, and openings at either end connected by a gut. It was found in Ediacaran Period deposits in Australia and was 2-7 millimeters long, with the largest the size of a grain of rice.
