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.

Human reproductive ecology (Evolutionary biology 🧬)

Human reproductive ecology is a subfield in evolutionary biology that is concerned with human reproductive processes and responses to ecological variables. It is based in the natural and social sciences, and is based on theory and models deriving from human and animal biology, evolutionary theory,...

Xenobots are microscopic, programmable biological machines constructed entirely from living cells without any genetic modification. Measuring less than a millimeter, they lack traditional mechanical parts and are entirely organic, biodegradable, and derived primarily from embryonic stem cells of the African clawed frog (Xenopus laevis).

Molecular emergence is the scientific phenomenon in which simple chemical building blocks combine to form complex systems with entirely new, unpredictable properties that cannot be derived from their individual components. It provides a theoretical framework for understanding the profound transition from non-living matter to self-replicating, living systems.

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.

Hello all. I am still getting a hang of this system, but here is an #introduction

I am a PhD student at WashU working with David Queller and Joan Strassmann at WashU. My broad interests span the evolution of cooperation and conflict and its consequences on biological complexity and major transitions. I use empirical (social amoebae) and theoretical approaches to my research. #evocell #evodevo #ecology #EvolutionaryBiology #evolutionarydynamics #EvolutionaryGenomics #theoreticalbiology
