Ebola (Orthoebolavirus zairense) is a highly sophisticated filovirus that relies on complex molecular evasion, the exploitation of immune-privileged sanctuaries, and the induction of societal disruption to ensure its survival and propagation, challenging its traditional, simplified classification as merely an agent of acute hemorrhagic fever.

Okay, I put off watching the latest ZeFrank video because it seemed to be about honeybees, which are boring (sorry bee people), but it's actually an amazing journey through geometry, evo-devo, the other, cooler Hymenoptera such as wasps, solitary bees, and ants, the evolution of eusociality, "stigmergy" (a new one for me), and more!

1. The Zoologist's Guide to the Galaxy: What Animals on Earth Reveal About Aliens—and Ourselves by Arik Kershenbaum, 2020

Applying the universal laws of evolutionary biology to the cosmos, this book brilliantly argues that because natural selection dictates form and function, alien life-forms will inevitably move, breathe, and communicate in ways strikingly similar to Earth's animals.

Allostasis is the sophisticated, anticipatory biological process wherein the brain dynamically alters internal physiological parameters to meet predicted environmental demands, while allostatic load is the cumulative cellular and systemic wear-and-tear resulting from the chronic overactivation of this predictive regulatory system.

This week's #NewBooks at the library: Who is excited about the next few books he will be reviewing?

- After an impressive debut, I am looking forward to reading Cal Flyn's second book, The Savage Landscape: How We Made the Wilderness, published by HarperCollins.

- Time for another deep dive into the history of my favourite discipline, #EvolutionaryBiology. I really enjoyed Costa's annotated version of Wallace's notebook, and am very excited about delving into this annotated version of #CharlesDarwin's The Descent of Man, beautifully published here by @princetonupress. Expect me to go dark for a while, it's over 760 pages!

- And for context, I will be adding a review of Jeremy DeSilva's A Most Interesting Problem: What #Darwin’s Descent of Man Got Right and Wrong about #HumanEvolution, published a few years back, also by Princeton.

Negative hysteresis is an evolution-informed treatment strategy where an initial exposure to one antibiotic predictably induces a temporary cellular vulnerability in a bacterial pathogen to a second, different antibiotic. In the pathogen Pseudomonas aeruginosa, pretreatment with a β-lactam robustly sensitizes the bacteria to a subsequent aminoglycoside attack.

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.

Benthic Origins of Early Eukaryotes

New research reveals early eukaryotes lived in oxygenated seafloors 1.7 billion years ago, explaining their billion-year evolutionary delay.
