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.

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.

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.

When an animal moves, its visual system adjusts its neuronal activity to process the changing environmental input, but this adjustment operates on the same mathematical evolutionary principles across both mice and primates despite differing sensory outputs.

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.

We are a species strictly engineered for deep, empathetic connection. Protecting the integrity of that connection—by understanding exactly how it functions, how it is genetically moderated, and how malevolent actors can exploit it—is arguably the most critical scientific and societal endeavor of our time.

This week's #NewBooks at the library:
- Another second-hand volume to my growing collection of The Correspondence of #CharlesDarwin, this one Volume 26: 1878, published by Cambridge University Press.
- #Warhammer: The Art of #GamesWorkshop, a rather rare exhibition catalogue of grimdark artwork that I bought via eBay.
- I Have Landed: The End of a Beginning in #NaturalHistory, the final of the essay bundles from #StephenJayGould, published by Harmony Books.

This week's #NewBooks at the library:
- I found a much reduced copy of Contesting Earth's History in Transatlantic Literary Culture, 1860–1935: Believers and Visionaries on the Borderlines of #Geology and #Palaeontology, published by Oxford University Press
- I was so taken with Guillermo del Toro's visual take on #Frankenstein, I bought the book on the making of the movie by Sheila O'Malley, published by Titan Books.
- I found a second-hand copy of The Spirit of System: #Lamarck and #EvolutionaryBiology, published by Harvard University Press, which should come in handy for a future review on Lamarck.

The rate-mismatch hypothesis posits that global mass extinctions occur when the pace of environmental change outstrips the rate at which biological life can undergo evolutionary adaptation. It provides a mathematical model linking Earth's historic extinction events to the critical disparities between environmental shifts and species' adaptive capabilities.

The ability to form and break habits is an evolutionary adaptation that allows animals to automate complex tasks, significantly reducing mental effort and preserving cognitive resources for survival.

Interspecies cooperation is a behavioral phenomenon where animals from different species work together for mutual benefit by exchanging information. This teamwork relies heavily on communication through specific cues and signals to coordinate complementary actions and achieve shared goals.

Behavioral ecology is the study of the evolutionary basis for animal behavior due to ecological pressures. It examines how behavior evolves, functions, and adapts in response to an organism's environment.

Avian kleptoparasitism is a behavioral ecological phenomenon wherein birds steal nest-building materials, such as twigs and moss, from the nests of neighboring individuals rather than foraging for them independently.

#introduction
hei,
finally found my way :)
great to see the #evolution and #ecology community here!
hope to share some of our research taking place at the #UniversityOfHelsinki on #EcoEvolutionaryModelling, #ExperimentalEvolution, #genetics of #adaptation, and #ComputerModelling in #EvolutionaryBiology, with a focus on genetics of #ComplexTraits, #QuantitativeGenetics, and #PopulationGenetics, not forgetting #EcoEvolutionaryDynamics.

#Introduction:

Hi everyone!

I am an Associate Professor in the Dept. of Biological Sciences at #VirginiaTech. I study #evolutionarybiology in #snakes, #lizards, #birds, and other organisms. I use #quantitativegenetics, #bioinformatics, and #theory to understand #evolution of complex #phenotypes.

I'm not posting a lot right now, but that might change. Expect mostly #science, #academia, etc. Will keep #music and #baseball on the birdsite for now.

Following everyone back for a limited time.

#introduction
👋 :mastodon:,
I'm a researcher at #INRAE-Nouzilly (France) studying #quantitativegenetics of #chicken #behaviour (especially #socialbehavior) to improve #animalwelfare

I tackle these questions using my background from #EvolutionaryBiology. I've investigated how #sexualselection and #genetic constraints (#pleiotropy, between life stages & sexes) can drive the #evolution of phenotypes & behaviours in red #junglefowl and #drosophila (some cool stuffs to be published soon!)
