weird question for people who study the evolution of plants: The ability of trees to generate cloud seeding aerosols seems like an advantageous adaptation, any idea when it evolved?

Mutual Aid a Factor of Evolution - Introduction
In a real sense, men are the product of women.
😃 So it's not my fault?
Finally, a book on women as evolutionary drivers.
A question for evolutionary biologists: has there ever been an evolutionary mutation that has been as destructive of the ecosphere as humans? Secondly, if mutations are adaptations to the environment how do we explain a mutation that destroys it? In other words, should the wider environment act as a regulator? Apologies if these are dumb questions. #evolution #biology #climate #EvolutionaryBiology

There is no universal law that says 100% of reality needs to be comprehensible to a species that evolved brains just savvy enough to catch our babies as they fall out of a tree and avoid snakes on the savannas. That we've used this basic wiring to tease out so much of how and why reality operates is nothing short of remarkable.

I really enjoy sweet bread.
Hallah, brioche, dinner rolls - incredible.
Add in some raisins, as a treat? Incredible!
Billions of years of evolution and thousands of years of societal progress enables me to eat lemon poppy seed loafs and that is SO great.
Notably, wonder bread and similar sweet bread products don't do it for me. Something about what they represent to me, I think.

Good morning. 🕊️☮️☕
27 September 2023
Years ago, at work, in a conversation with a couple of my work friends, and the subject of biological evolution came up. I tried to explain that natural selection is a real thing, which only made them angry. Of course, they pointed out that the "Theory of Evolution" was only a theory and I pointed out that the definition of a scientific theory wasn't. what they thought it was. We went on and on, but they were absolutely positive that the Earth was only about 6000 years old. etc., etc., etc. So, I shut up and let them be. Though, I'm still confounded to this day about how closed-minded people can be even when presented with evidence.

A tiny sea creature called a comb jelly has a surprising role in human evolution, a new study reveals. This creature, which is not related to jellyfish, has a nervous system that is more complex than previously thought. The study suggests that the nervous system evolved independently in different branches of life, and that humans share some genes with comb jellies.
“If a group of animals doesn’t need to ‘think,’ evolution will remove their brains. ‘We burn so many calories in our heads. Why would you maintain this expensive information-processing organ if you don’t need it?’” From a story by Michael Marshall in The Guardian on whether sponges or comb jellies were the first evolutionary “trailblazers.” https://www.theguardian.com/science/2023/sep/09/sponge-versus-comb-jelly-ancestor-evolution-debate #brains #evolution
Evolution of Thought and the Uncanny Valley
In this AI episode -- starring Atomic Dave and AI research -- we dig into the idea of how thought and thinking has evolved over the last century and led us deeper into the Uncanny Valley.
Only 22% of Americans believe humans evolved without God's intervention. 40% are straight-up creationists.
With poll results like these how Americans can hope to solve any complex problems that ail them? Without critical thinking skills in the population how a #democracy can even function?

"Ornithomimosaurs first appeared in the Early Cretaceous and persisted until Late Cretaceous. Almost all of them were toothless, and apparently their jaws were covered by a horny beak; they also had very long legs and arms."
the podcast arthro-pod has recently released two great works, one on insect wings and one on insect legs, which cover the shape, parts, adaptations, and evolutionary history of insect wings and legs.
The wings episode covers four different hypotheses for how wings evolved, which is more than the usual two.

6/6 I’ve implemented this a couple of times in my #engineering work over the years and it’s fascinating to watch #evolution in action, right there on my computer, coming up with implausibly complex solutions that I never explicitly specified because I never knew them—or had to know.
Emergent complexity arising from nothing but mutation, crossover, natural and sexual selection, and genetic drift. Give it a billion years or two and you may even see microscopic floating blobs turn into people.

And if you have a cat, this comes to no surprise:
They continue to be master manipulators doing things like changing their purrs and “meow” to curry human favor.

HENRY ROLLINS: Why I Stopped Making Music
During a recent appearance on producer Rick Rubin's "Broken Record" podcast, punk rock icon Henry Rollins discussed his decision to stop making music 15 years ago
Sometimes I sit back and contemplate the theory of #evolution by natural selection (and other types of selection). The explanatory power is just amazing, and it's philosophical implications are probably under appreciated.
Evolution is the "impending change for betterment" - Systemic Evolutions
Change for the betterment of all.
House cats evolved in the deserts of Africa and the Mideast -- an environment in which fish are exceedingly uncommon. Why, then, do kittehs have such a strong liking for tuna and other fish? Researchers think they've found part of the reason.
The symbiotic organisms could need more than a million years to adapt to just 1 degree Celsius of warming.
Scientists have long known that #lichens grow at a staggeringly slow rate. Some are thousands of years old and grow just millimeters each year. Now, new research suggests lichens are struggling to keep up with the changing climate.
#Human ancestors nearly went extinct 900,000 years ago
A new technique analysing modern #genetic data suggests that pre-humans survived in a group of only 1,280 individuals.
“About 98.7% of human ancestors were lost,” says Haipeng Li, a population geneticist at the University of Chinese Academy of #Sciences in Beijing, who co-led the study. He says that the fossil record in Africa and Eurasia between 950,000 and 650,000 years ago is patchy and that “the #discovery of this bottleneck may explain the chronological gap”.

What’s the World’s Oldest #Language?
Debate rages over which #languages can claim to have the earliest #origin
"These languages and dead ones that are no longer spoken weave together millennia of human interactions. That means the task of determining the world’s oldest language is more than a #linguistic curiosity. For instance, in order to decipher clay tablet inscriptions or trace the #evolution of living tongues, linguists must grapple with questions that extend beyond language. In doing so, their research reveals some of the secrets of ancient civilizations and even sparks debates that blend #science and #culture."
