Professor of paleontology and Earth systems at Vilnius University. My interests are: theoretical paleontology, evolution, geology, stratigraphy, philosophy of biology and geology, climate at scales great and small.

@andrejpaleo.bsky.socialArcheologists in the popular news scooped paleontologists of dinosaur discoveries, way before the AI started scooping mathematicians of their theorem proofs!
@andrejpaleo.bsky.socialOh a marvelous post about AI solutions to math problems using dinosaur paleontology as a metaphor.

@andrejpaleo.bsky.socialSo, the math will work more and more like the science when building something, we are accepting modules of apparent truth without ever explicit understanding them? Science with AI input will be even more cognitively opaque for humans?
Honest mathematician:

@andrejpaleo.bsky.social"US proposes $100,000 charge for international students to do post-graduate work"
But why you would do such foolish thing on yourself? They want to reap money for prestige, sacrificing cheap high-level international tallent intake.

@andrejpaleo.bsky.socialSediments, geochemistry, taphonomy as well as evolutionary patterns usually point to the same transformative events if you know how to read:
"The Choteč Limestone-Kačák Member succession represents ... favorable...preservation of microbial microfabrics."

@andrejpaleo.bsky.socialAnd as you can guess, this mechanism should accelerate the evolution and could be one of the enablers of the punctuated change during cladogenesis.
@andrejpaleo.bsky.socialA new study by Andrii Rozhok, Niles Eldredge, and James DeGregori which presents a novel population genetic mechanism of evolution—the directional selection (of deviating forms) also selects, as a dynamic spandrel, higher mutation rate forms!

@andrejpaleo.bsky.social'Phylogenetic jungle' of early ecomorphologically diverse actinopretygians:

@andrejpaleo.bsky.socialAs AI systems become more capable in helping in the scientific inference, the challenge becomes the understanding of their inner workings and biases which they can introduce (in arguably different inhuman ways) in the study.

@fossilsndcoffee.bsky.socialReposted by @andrejpaleo.bsky.socialSo in what is unfortunately now an ~annual~ reminder - the Paleontological Research Institution is not presently affiliated with Cornell and was never a part of Cornell. Some PRI folks have taught students at Cornell, but donating to PRI supports Research and Education, and doesn't support Cornell
@andrejpaleo.bsky.socialTrue. The correct and fruitful identifications of the unknown in the field is the first step in setting and exciting journey of discovery!
