Fossil-calibrated inference of divergence times among the Volvocine algae enables reconstruction of the steps that led to differentiated multicellularity

This study uses comparative genomics and fossil data to infer divergence times in volvocine algae, revealing the evolutionary sequence leading to multicellularity and gamete differentiation.

Phylotranscriptomics points to multiple independent origins of multicellularity and cellular differentiation in the volvocine algae

This study uses transcriptomic data to show multicellularity and cellular differentiation evolved multiple times in volvocine algae, challenging previous single-origin hypotheses.

Evolutionary dynamics of de novo mutations and mutant lineages arising in a simple, constant environment

This study tracks de novo mutations in E. coli populations under glucose-limited conditions, revealing clonal interference as the dominant evolutionary mechanism.

Fitness and productivity increase with ecotypic diversity among E. coli evolved in a simple, constant environment

The paper shows that ecotypic diversity in E. coli increases fitness and productivity through cooperative interactions in a constant environment.

Discrete Community Assemblages Within Hypersaline Paleolake Sediments of Pilot Valley, Utah

This study analyzes microbial communities in hypersaline paleolake sediments of Pilot Valley, Utah, revealing three discrete community groups and potential halophilicity in Gemmatimonadetes.

De novo origin of multicellularity in response to predation

This study shows that predation can drive the evolution of multicellularity in the green alga Chlamydomonas reinhardtii, with two populations developing multicellular structures that enhance survival against the predator Paramecium tetraurelia.

Motility in multicellular Chlamydomonas reinhardtii

This study investigates motility in newly evolved multicellular strains of Chlamydomonas reinhardtii and finds they lack directional movement despite functional flagella.
