Phylogeny and Molecular Evolution of the Green Algae
The green lineage (Viridiplantae) comprises the green algae and their descendants the land plants, and is one of the major groups of oxygenic photosynthetic eukaryotes. Current hypotheses posit theExpand

Triassic origin and early radiation of multicellular volvocine algae
Evolutionary transitions in individuality (ETIs) underlie the watershed events in the history of life on Earth, including the origins of cells, eukaryotes, plants, animals, and fungi. Each of theseExpand

Parallel Evolutionary Dynamics of Adaptive Diversification in Escherichia coli
The divergence of Escherichia coli bacteria into metabolically distinct ecotypes has a similar genetic basis and similar evolutionary dynamics across independently evolved populations.

Sciurid phylogeny and the paraphyly of Holarctic ground squirrels (Spermophilus).
The squirrel family, Sciuridae, is one of the largest and most widely dispersed families of mammals. In spite of the wide distribution and conspicuousness of this group, phylogenetic relationshipsExpand

Comparative mitochondrial genomics of snakes: extraordinary substitution rate dynamics and functionality of the duplicate control region
BackgroundThe mitochondrial genomes of snakes are characterized by an overall evolutionary rate that appears to be one of the most accelerated among vertebrates. They also possess other unusualExpand

Phylogeny and historical biogeography of African ground squirrels: the role of climate change in the evolution of Xerus
We used phylogenetic and phylogeographical methods to infer relationships among African ground squirrels of the genus Xerus. Using Bayesian, maximum‐parsimony, nested clade and coalescent analyses ofExpand

  • 20 October 2008
Among biologists, there is no general agreement on exactly what entities qualify as ‘organisms’. Instead, there are multiple competing organism concepts and definitions. While some authors think thisExpand

Experimental evolution of an alternating uni- and multicellular life cycle in Chlamydomonas reinhardtii
The transition to multicellularity enabled the evolution of large, complex organisms, but early steps in this transition remain poorly understood. Here we show that multicellular complexity,Expand

Cooperation and conflict during evolutionary transitions in individuality
Cooperation received much less attention 30 years agothan other forms of ecological interaction, such ascompetition and predation. Workers generally viewedcooperation as being of limited interest, ofExpand
