Summary:

Two closely related viruses that have been introduced to northern Spain in recent years have already led to the collapse of three different species of amphibian -- the common midwife toad, the common toad, and the alpine newt -- in the protected area of Picos de Europa National Park. In all, six amphibian species have suffered from severe disease and mass mortality and researchers say that the viruses appear to be on the move.

Neanderthals in Northern Spain Had Knowledge of Plants' Healing Qualities, Study Reveals

ScienceDaily (July 17, 2012) — An international team of researchers, led by the Universitat Autònoma de Barcelona and the University of York, has provided the first molecular evidence that Neanderthals not only ate a range of cooked plant foods, but also understood its nutritional and medicinal qualities.

Until recently Neanderthals, who disappeared between 30,000 and 24,000 years ago, were thought to be predominantly meat-eaters. However, evidence of dietary breadth is growing as more sophisticated analyses are undertaken.

Researchers from Spain, the UK and Australia combined pyrolysis gas-chromatography-mass spectrometry with morphological analysis of plant microfossils to identify material trapped in dental calculus (calcified dental plaque) from five Neanderthals from the north Spanish site of El Sidrón.

Their results, published inNaturwissenschaften - The Science of Nature this week, provide another twist to the story -- the first molecular evidence for medicinal plants being used by a Neanderthal individual.

The researchers say the starch granules and carbohydrate markers in the samples, plus evidence for plant compounds such as azulenes and coumarins, as well as possible evidence for nuts, grasses and even green vegetables, argue for a broader use of ingested plants than is often suggested by stable isotope analysis.
