High adsorption rate is detrimental to bacteriophage fitness in a biofilm-like environment.

3 Oct 2009 BACKGROUND: Bacterial biofilm is ubiquitous in nature. However, it is not clear how this crowded habitat would impact the evolution of bacteriophage (phage) life history traits. In this study, we constructed isogenic lambda phage strains that only ... Read more...

Reexamining human origins in light of Ardipithecus ramidus.

30 Sep 2009 Referential models based on extant African apes have dominated reconstructions of early human evolution since Darwin's time. These models visualize fundamental human behaviors as intensifications of behaviors observed in living chimpanzees and/or ... Read more...

The impact of population size on the evolution of asexual microbes on smooth versus rugged fitness landscapes.

16 Sep 2009 BACKGROUND: It is commonly thought that large asexual populations evolve more rapidly than smaller ones, due to their increased rate of beneficial mutations. Less clear is how population size influences the level of fitness an asexual population can ... Read more...
