We identified protein domains in LUCA (Last Universal Common Ancestor). Their distinctive amino acid usage reveals the order amino acids were added to the genetic code, based mostly on size. Older proteins hint at earlier alternative codes. 1/15 @seekingluca.bsky.social www.pnas.org/doi/10.1073/...

Funny! this brings back memories of when Nüsslein-Vollhard told a fellow female graduate student that she wouldn’t hire a postdoc who wastes time putting on makeup everyday.
The one piece of advice by a Nobel laureate that didn’t improve my science, but my morning routine.

This is exactly right. Population genetics has a reification of simple models problem. And we are weirdly non-Bayesian in that we do not check our simple - clearly too simple! - models against the priors generated through direct observation in ecology and other fields.

#evolution

Excited to share our new paper out in Science! We combined simulations, experiments, and field data to show how dispersal simultaneously stabilizes species and genetic diversity, which results in persistent eco-evo dynamics. doi.org/10.1126/scie...

Putting my stake in the ground as an enjoyer (and user) of the term 'prokaryote'. It's an efficient way to talk about two groups of organisms which are very often talked about in the same breath! Nobody gets mad about 'fish' because it's paraphyletic! 🧪

Obsession with methods in microbial ecology Striving towards bare minimum technique awesomeness

In my latest newsletter I write about the obsession with methods in microbial ecology, and I share my admiration of simple, but elegant experimental approaches.

Bacterial ecology and evolution converge on seasonal and decadal scales Ecology and evolution are distinct theories, but the short lifespans and large population sizes of microbes allow evolution to unfold along contemporary ecological time scales. To document this in a natural system, we collected a two-decade, 471-metagenome time series from a single site in a freshwater lake, which we refer to as the TYMEFLIES dataset. This massive sampling and sequencing effort resulted in the reconstruction of 30,389 metagenomic-assembled genomes (MAGs) over 50% complete, which dereplicated into 2,855 distinct genomes (>96% nucleotide sequence identity). We found both ecological and evolutionary processes occurred at seasonal time scales. There were recurring annual patterns at the species level in abundances, nucleotide diversities (π), and single nucleotide variant (SNV) profiles for the majority of all taxa. During annual blooms, we observed both higher and lower nucleotide diversity, indicating that both ecological differentiation and competition drove evolutionary dynamics. Overlayed upon seasonal patterns, we observed long-term change in 20% of the species' SNV profiles including gradual changes, step changes, and disturbances followed by resilience. Most abrupt changes occurred in a single species, suggesting evolutionary drivers are highly specific. Nevertheless, seven members of the abundant Nanopelagicaceae family experienced abrupt change in 2012, an unusually hot and dry year. This shift coincided with increased numbers of genes under selection involved in amino acid and nucleic acid metabolism, suggesting fundamental organic nitrogen compounds drive strain differentiation in the most globally abundant freshwater family. Overall, we observed seasonal and decadal trends in both interspecific ecological and intraspecific evolutionary processes. The convergence of microbial ecology and evolution on the same time scales demonstrates that understanding microbiomes requires a new unified approach that views ecology and evolution as a single continuum. ### Competing Interest Statement The authors have declared no competing interest.

Been dreaming of this paper for a decade. 1 PhD and 1 postdoc later, here it is!

What do ecology and evolution look like in a 20-year microbiome time series? They blur together

Interesting! Their theory seems to hinge on constant recombination (which in the face of niche overlaps forces low-diversity populations to increase their niche breadths instead of e.g. diversifying into more narrow but multimodal distributions). No such homogenizing recombination in Bacteria (?)

Ahhh to be a microbiologist in these exciting times when evolution and ecology talk to each other… absolutely brilliant talks at @meehubs.bsky.social

Wild animals are a tiny proportion.
