One of the greatest mysteries of evolutionary biology revolves around the question of how Earth´s original single-celled ancestors – the predecessors of all life on the planet – first made the critical transition to multicellularity. A new study published this week in Proceedings of the National Academy of Sciences (PNAS), however, points out that the switch may not have been as difficult as most scientists have speculated. The traditional paradigm for attempting to...

One of the most pivotal steps in evolution-the transition from unicellular to multicellular organisms-may not have required as much retooling as commonly believed, found a globe-spanning collaboration of scientists led by researchers at the Salk Institute for Biological Studies and the US Department of Energy's Joint Genome Institute. A comparison of the genomes of the multicellular algae Volvox carteri and its closest unicellular relative Chlamydomonas reinhardtii revealed that multicellular...

Scientists have for the first time determined the complete genome sequence of a brown alga and opened a new door to the understanding of multicellularity and photosynthesis. With the world's first complete sequencing of a brown algal genome, an international research team has made a big leap towards understanding the evolution of two key prerequisites for higher life on Earth - multicellularity and photosynthesis. As the internationally renowned science magazine "Nature" reported in its...
