Olusanya et al. study genetic load and extinction in a metapopulation. Their analysis is based on a novel theoretical framework that tracks the co-evolution of load and population sizes and gives a nuanced picture of the genetic and demographic factors that affect extinction.

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...

In simulation, Caudill & Ralph find that coevolutionary dynamics alone are not sufficient to produce the striking mosaic of levels of toxicity and resistance observed in nature, but with ecological heterogeneity, it did produce such patterns. https://www.journals.uchicago.edu/doi/10.1086/733456

"#ants began farming #fungi when an #asteroid struck Earth 66 million years ago. This impact caused a mass #extinction but also created ideal conditions for fungi to thrive. Innovative ants began cultivating the fungi, creating a partnership that became even more tightly intertwined 27 million years ago and continues to this day"
Speaking of machine learning, I once had a paper rejected from #ICML (International Conference on Machine Learning) in the early 2000s because it "wasn't about machine learning" (minor paraphrase of comments in 2 of the 3 reviews if I recall correctly). That field was consolidating--in a bad way, in my view--around a very small set of ideas even back then. My co-author and I wrote a rebuttal to the rejection, which we had the opportunity to do, arguing that our work was well within the scope of machine learning as set out by Arthur Samuel's pioneering work in the late 1950s/early 1960s that literally gave the field its name (Samuel 1959, Some studies in machine learning using the game of checkers). Their retort was that machine learning consisted of: learning probability distributions of data (unsupervised learning); learning discriminative or generative probabilistic models from data (supervised learning); or reinforcement learning. Nothing else. OK maybe I'm missing one, but you get the idea.
We later expanded this work and landed it as a chapter in a 2008 book Multiobjective Problem Solving from Nature, which is downloadable from https://link.springer.com/book/10.1007/978-3-540-72964-8 . You'll see the chapter starting on page 357 of that PDF (p 361 in the PDF's pagination). We applied a technique from the theory of coevolutionary algorithms to examine small instances of the game of Nim, and were able to make several interesting statements about that game. Arthur Samuel's original papers on checkers were about learning by self-play, a particularly simple form of coevolutionary algorithm, as I argue in the introductory chapter of my PhD dissertation. Our technique is applicable to Samuel's work and any other work in that class--in other words, it's squarely "machine learning" in the sense Samuel meant the term.
Whatever you may think of this particular work of mine, it's bad news when a field forgets and rejects its own historical origins and throws away the early fruitful lines of work that led to its own birth. #GenerativeAI threatens to have a similar wilting effect on artificial intelligence and possibly on computer science more generally. The marketplace of ideas is monopolizing, the ecosystem of ideas collapsing. Not good.

Once we imitated enough sounds, we had a repertoire from which to #remix.
Here's a #coevolution fractal duality: #adaptation & #exaptation. Copy/re-create & adopt what exists, and/or modify & repurpose/create something new. (repeat)
After sharing common perception of sound, sight, smells, taste & touch, we were left with the still difficult part of putting words to our feelings & emotions. Hard to escape the abstraction there.
At last, we're able to share our latest work on #plant #immune system #pangenomes, focusing on #NLR genes in #arabidopsis
"Pangenomic context reveals the extent of intraspecific plant NLR evolution"
