Antibiotic-resistant bacteria possess a critical vulnerability within their cell wall transport systems that, when disrupted, drastically reduces their resistance. This discovery reveals an evolutionary trade-off where the genetic mechanisms bacteria use to survive antibiotic exposure can simultaneously be exploited to make them susceptible to existing treatments.

Coevolution (Habitat 🌄)

In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution. Charles Darwin mentioned evolutionary i...

It is a remarkably humbling realization that a single, unnoticed bite from an arthropod the size of an apple seed can completely rewrite an individual's relationship with the global food chain. Alpha-gal syndrome reminds us that the human immune system, for all its staggering sophistication and atomic-level precision, remains intimately and sometimes precariously tethered to the natural world.

So if I understood this article correctly, the key conclusion is this - metamorphosis was not the condition for moving onto land?

The traditional picture was:

Tetrapods could leave water because they first evolved a tadpole-like larval stage and then metamorphosed.

The new interpretation suggested by these fossils is closer to:

Tetrapods gradually adapted to land over evolutionary time, and they probably did not need a frog-like metamorphosis to do it.

In other words, metamorphosis was probably not a prerequisite for terrestrial life. Instead, the transition from water to land appears to have been a long, gradual evolutionary process affecting the whole life cycle, rather than depending on a distinct larval stage.

Analogy of two possible scenarios:

Old model

• Young live in water.
• Undergo a major developmental transition.
• Adults become adapted to life on land.

New model

• Young and adults share the same basic body plan.
• Land adaptations accumulate gradually over millions of years (generations).

So the narrative shifts from:

Metamorphosis enabled the move onto land

to:

The move onto land happened gradually, and amphibian-style metamorphosis likely evolved later as a specialized adaptation.

The earliest known eukaryotic organisms were exclusively benthic, inhabiting shallow, oxygenated marine seafloors rather than drifting in the anoxic open oceans. Their evolution and geographic distribution were fundamentally constrained by the highly localized availability of oxygen.

Understanding quorum sensing fundamentally reframes microscopic organisms not as solitary entities, but as highly social, coordinated societies. By intercepting these chemical lexicons, modern science can sustainably manage devastating human diseases, balance complex ecosystems.

We invite highly motivated and experienced students and early-career researchers to join our group in Bonn for a visiting research stay. This is a great opportunity to gain hands-on experience, exchange ideas, and work in a collaborative and supportive scientific environment with excellent computational resources.

Sister group (Evolutionary biology 🧬)

In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative of another given unit in an evolutionary tree.

I’m an evolutionary biologist at the Institut de Biologie de l’École Normale Supérieure in Paris. I’m interested in explaining variation in biodiversity under an evolutionary perspective. For that I develop and apply phylogenetic probabilistic models of diversification, biogeography and trait evolution using Bayesian inference. #introducion #SSEfolks #asnfolks #SSB #EvolutionaryBiology #julialang #bayesian
