Explore the evolutionary links between living things with the Wellcome Trust's Tree of Life, developed as part of our Darwin 200 activities, which celebrate the 200th anniversary of Charles Darwin's birth. This six-minute Tree of Life video also appeared on the BBC One programme 'Charles Darwin and the Tree of Life' narrated by David Attenborough. In addition to the video, an interactive version of the 'Tree of Life' here ( http://www.wellcometreeoflife.org ) has been created to allow...

The Evolution of Small Bacterial Genomesin the Ultra-Oligotrophic Ocean

submitted by: dougramsey
The size and coding capacity of a genome are its most fundamental properties. What selective pressures deter mine the expansion and contraction of genomes, and how is genome size related to adaptive strategies? Very small marine microbial genomes are providing new insights into these questions. The first reports of genome sequences from the cyanobacterium Prochlorococcus and the α-proteo bacterium SAR11 (Pelagibacter) established that these very abundant marine bacterioplankton clades have...
