A new preprint! Data from a huge experiment by @prczhaoyansong.bsky.social show that similar microbial communities diverge depending on whether the carbon source is glucose or its polymer, cellulose. Diversity is comparable, but biomass, functions and taxonomy differ:

Diverse microbial communities assemble on both recalcitrant and labile carbon sources
Microbial community assembly is shaped by the nature of available resources, with labile carbon sources such as glucose often expected to support low diversity due to rapid growth and competitive excl...

Mutation rates vary within genomes.., sure, but: @andydfarr.bsky.social describes a single transcription-dependent C->T mutation in the promoter of rpoS that is ~5,000 times > background. Are promoters places where shit happens, or facilitators of adaptive change? journals.plos.org/plosgenetics...
An extreme mutational hotspot in nlpD depends on transcriptional induction of rpoS
Genetic mutations drive evolution, with effects ranging from harmful to beneficial. While typically considered random, some genomic positions – called “mutational hotspots” – mutate more frequently. H...

A recent paper
www.science.org/doi/10.1126/... described the evolution of evolvability in 46 mutational steps. The refining hand of selection - working lineages - was key, but @michael-barnett.bsky.social used just 8 lineages 🫠. Can selection above the level of the individual really be so potent?

Experimental evolution of evolvability
Evolvability—the capacity to generate adaptive variation—is a trait that can itself evolve through natural selection. However, the idea that mutation can become biased toward adaptive outcomes remains...
