The gene weavers

Article Abstract:

Biologists suggest that viruses have a large part to play in the evolution of life on Earth due to their finding that every phage they come across is almost completely different from the next. Viruses are a major driving force in the evolution of higher organisms and a comparison of 14 different phages indicated that phages could combine bits of DNA even when there is no similarity between the sequences of the different DNA pieces.

Geobiology of a microbial endolithic community in the yellowstone geothermal environment

Article Abstract:

The discovery and identification of the constituents of an extremely acidic (pH 1) endolithic microbial community inhabiting the pore space of rocks in the geothermal environment of Yellowstone National Park, USA, is described. The remnants of these communities could serve as biosignatures and provide important clues about ancient life associated with geothermal environments on the Earth or somewhere in the Solar System.

Time for a change

Article Abstract:

Comparisons of ribosomal RNA sequences show a three-domains three of life, which is an experimentally derived map of biological organization and the course of evolution at the largest scale. It is found that the use of the term 'prokaryote' fails to recognize that an idea about life's origins has been proved wrong.
