Learned that a lot of young Earth creationists now argue that microevolution is real but does not explain the diversity of species. Thus, they have recreated the 20th century schism between Darwinism and paleontology/genetics from 1st principles.
So many marine snails being such vicious predators is such a fascinating zoology fact.

I mean just look at this nonsense. This isn’t necessary, be normal and just make your premaxilla longer!

I am recruiting Ph.D. students this cycle. Students interested in deep-sea fishes and phylogenetic comparative methods are an especially good fit.
As a kid, I was told that video games cause violence. As an adult, I know that Microsoft Word causes more violent thoughts than any video game
I hope we find a new species of this taxon someday and name it after the very deserving @mosasaurologist.bsky.social.
John P. Friel, Ph.D.@friel.bsky.social · last wk.Dear @mosasaurologist.bsky.social, I am so very sorry. 😂
The "AI companies are buying old/rare books in bulk and shredding them to feed their models" is a rare case of me hating being right. Sources of real human language uninfluenced by chatbots are now extremely valuable, particularly those not on the internet. If you need old books, get them now.
At least a lawn can be transformed into a mini-biodiversity reservoir with insects, arthropods, and native plants. Even a golf course can have flowers and birds. Insane how we can finds billions to build datacenters but not invest in healthcare, education, real infrastructure, or jobs.
Jack Stack@jackstack.bsky.social · last wk.I love arguments that invoke water spent on golf courses, which is something environmentalists also oppose! A hundred years from now the water and land we are wasting will be seen as an insane thing of the past, similar to how we view people who ate mummies or slaughtered bison.

Dave Karpf@davekarpf.bsky.social · last wk.I'm reading the "environmentalists are wrong about data centers" piece from the NYT and ohmygoditssofuckingbad. Apparently, so long as you're punching left, they'll just let you say any goddamn thing you please... www.nytimes.com/2026/07/25/o...
Alligator gars are so insanely cool when you think about it. Giant predator with little change over a hundred million years, like running into an actual cryptid.
My hottest science take is that Bigfoot was real and captured by Theodore Roosevelt on an expedition to Wyoming.
The fun science fiction around Megalodon has also created the opposite problem, many of my students don’t even know it was a real animal!
Lisa Whitenack, PhD@whitenacklab.bsky.social · last wk.Whelp, it’s that time of year again. The time where I have to once again remind people: that the giant shark known as Megalodon is super extinct and has been for several million years. Yes, we know for sure. Yes, the ocean is really big. But our current ecosystem cannot sustain it.
Any invertebrate zoologists: looking for resources to store and properly curate extant specimens. Anything from boxes to advice. Have a teaching collection that needs love, because this type of thing makes me sad. I want to teach this part of the animal kingdom as best I can!
The crickets in my house have given me the power to hop around and cause general annoyance
🌻OK MR. SUNSHINE!🌻@entobiologist.bsky.social · 2w agoa tree cricket bit me a couple days ago and it left a mark do i get tree cricket powers now
I think species are real and are well defined by the biological species concept. Discuss in the replies…
The more I learn about macroevolution the less I understand it
Looks awesome!
