Evolution

Overlooked life on seabed gorges on fish faeces

Bacteria are not the only organisms that feed on dead plankton and fish faeces. The so-called ‘archaea’ also play an important – and hitherto overlooked – role in carbon cycling in the seabed.

Sea snakes break rules of evolution

Evolutionarily speaking, sea snakes are some pretty weird creatures. They have evolved both large and small heads very quickly and apparently without being separated geographically.

Three in four chimpanzee species live in European zoos

Danish researchers have found three out of the four existing subspecies of chimpanzees in the European zoo population. The chimpanzees can be used to consolidate existing breeding programmes and launch new ones.

Anus-mouthed worm looks like our earliest ancestor

Scientists have finally succeeded in studying the development of a tiny Swedish worm. Its mouth and its anus are in the same spot and the worm is a primitive form of man.

Butterflies fly 3,500 km by compass

Monarch butterflies fly from Canada to Mexico using only an internal compass and the landscape to guide them. Now researchers can explain how.

Evolution: giant leaps or half measures?

New statistical analyses suggest that evolution does not happen gradually through intermediary generations, but in a large single leap to new species.

Bacteria thrive at the bottom of the Mariana Trench

Scientists have found bacteria in one of the world’s most hostile and extreme environments 11 km below sea level.

Live bacteria found deep below the seabed

Scientists have found live microbial communities in the earth’s crust deep below the seabed. The discovery may affect our conception of Earth's orbit.

Butterfly hangs on for dear life

A century of strong winds on a tiny island in the Baltic Sea has created butterflies that are especially adapted to keep from blowing away.

Global warming also affects palm trees

Palms are slow to adapt or disperse in response to man-made climate change. This could spell the end for several palm species.
