How do you study a group of organisms with over 300,000 species, dispersed across all seven continents, and with up to 50 times as much DNA content as the human genome? This is the question posed to biologists studying the evolutionary history of flowering plants, called angiosperms, whose rapid diversification […]

If rocks from Earth containing microbial life entered Venus’s orbit in the past, this life may have adapted to Venus’s atmospheric conditions. The death of the dinosaurs 66 million years ago was caused by the impact of a huge asteroid on the Earth. However, paleontologists have continued to debate whether […]

The period preceding the emergence of behaviorally modern humans was characterized by dramatic climatic and environmental variability – it is these pressures, occurring over hundreds of thousands of years that shaped human evolution. New research published today in the Cambridge Archaeological Journal proposes a new theory of human cognitive evolution entitled ‘Complementary […]

A glasswing butterfly feeding at flowers in Costa Rica. The remarkable transparency of these butterflies allows them to be “invisible,” and the antiglare coating of their wings helps to prevent them from being given away by any glare of sunlight off their wings.

In a paper published in Science, biologists at Baylor College of Medicine, the Netherlands Cancer Institute and Rice University studying the tree of life unveil a new classification system for cell nuclei and the discovery of a method for transmuting one type of cell nucleus into another. This illustration shows […]

This artist’s illustration of Yamatosaurus izanagii (center) represents its ancestry to more advanced hadrosaurs (in the background). Credit: Artwork by Masato Hattori An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan’s southern islands. The fossilized discovery […]

Loch Torridon A billion year old fossil, which provides a new link in the evolution of animals, has been discovered in the Scottish Highlands. Scientists have discovered the fossil of an organism with two distinct cell types,  thought to be the oldest of its kind ever recorded The fossil reveals […]

Atlantic cod was once one of the most important fish species in the world. The big, long-lived predator helped feed Europe and North America for centuries. But decades of overfishing in the mid–20th century caused populations to crash, wiping out 30,000 jobs in Canada alone and financially devastating many coastal […]
