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.

Local evolutionary adaptation occurs when populations of a single species develop heritable, genetic traits that are finely tuned to the highly specific conditions of their immediate environment.

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.

The curator of our university Entomology museum, John Marris, excitedly popped into my office earlier today to share this neat new study on ant-associated beetles, by
Yu-Cheng Feng and colleagues.

These small beetles live inside ant nests. Not only have they evolved cunning ways to co-exist with the ants, but they have also evolved *handles* to help the ants carry them about. The phyologeny of the subfamily Chlamydopsinae suggests that these beetles have independently evolved ant handles several times.

"Our findings provide direct evidence that the characteristic surface relief of chlamydopsines, at least partly or in some cases, serves as a mechanical adaptation for ant‑mediated transport"

TITLE: Scientists challenge a 70-year-old “lizard brain” myth

URL: https://www.sciencedaily.com/releases/2026/08/260829235958.htm

A long-standing picture of brain evolution as newer, rational layers stacked on top of an ancient “lizard brain” may be deeply misleading. Researchers found that evolution instead appears to balance two competing styles of brain wiring, expanding one while shrinking the other depending on what an animal needs to survive.

Parasitic plants, such as dodders, acquire and permanently integrate functional foreign genes from their host plants through horizontal gene transfer (HGT). Instead of merely preserving these stolen genes, the parasites structurally remodel them over millions of years while retaining their original biological functions.

Quantum evolution (Evolutionary biology 🧬)

Quantum evolution is a component of George Gaylord Simpson's multi-tempoed theory of evolution proposed to explain the rapid emergence of higher taxonomic groups in the fossil record.

Ring species (Evolutionary biology 🧬)

In biology, a ring species is a connected series of neighbouring populations, each of which interbreeds with closely sited related populations, but for which there exist at least two end populations in the series which are too distantly related to interbreed, though there is a potential gene flow between linked neighbouring populations. Such non-breeding, though genet...

A 113-million-year-old mass extinction event of marine planktic foraminifera was driven by severe ocean acidification caused by massive volcanic carbon dioxide emissions. Microscopic fossil evidence confirms that acidic surface waters dramatically reduced the ability of these organisms to build calcium carbonate shells.

The history of life on #Earth is often viewed through a strictly #Darwinian lens of competition—a relentless, zero-sum struggle where every organism fights for a larger slice of a finite resource pie. In this narrative, nature is, as Alfred, Lord Tennyson famously wrote, "red in tooth and claw," dominated by predation, #parasitism, and the survival of the fittest.

Darwin and Wallace's original papers to the Linnean Society (published 1858) are fascinating reads, showing how they each developed the concept of natural selection. The foreword by Lyell and Hooker makes clear that Darwin was very reluctant to publish!

Both mention artificial selection, but Wallace uses the tendency of domesticated animals to "return to type" in the wild - seen at the time as some sort of stabilising force against change - to bolster the idea of natural selection.

On the tendency of species to form varieties; and on the perpetuation of varieties and species by natural means of selection. Journal of the Proceedings of the Linnean Society, Zoology. 3:45-62, 1858-9
