The rate-mismatch hypothesis posits that global mass extinctions occur when the pace of environmental change outstrips the rate at which biological life can undergo evolutionary adaptation. It provides a mathematical model linking Earth's historic extinction events to the critical disparities between environmental shifts and species' adaptive capabilities.

A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided...

Do you want to know how the structure of the rock record affects your reconstructions of #biodiversity, #evolution rates or trait evolution? The groundwork for doing this has been laid down in the field of #StratigraphicPaleobiology but until now no software tools have been available to researchers in #paleobiology and #geoscience to evaluate distortion of their #FossilRecord.
Join the webinar on Building modeling pipelines for stratigraphic paleobiology in #RSoftware by my PhD student @Niklas_Hohmann in the Paleoverse lecture series hhttps://palaeoverse.org/lectures this Thursday at 4 PM UTC to learn how to use the new package StratPal developed in my European Research Council (ERC) project #MindTheGap
You can find the package with extensive documentation here: https://mindthegap-erc.github.io/StratPal/

🔴 🇳🇴 Corroborating written history with ancient DNA: The case of the Well-man described in an Old Norse saga
"Here we apply palaeogenomic analysis to human remains excavated from a medieval well at the ruins of Sverresborg Castle in central Norway. In Sverris Saga, the Old Norse saga of King Sverre Sigurdsson, one passage details a 1197-CE raid on the castle and mentions a dead man thrown into the well. Radiocarbon dating supports that these are that individual’s remains."

“Organ systems of a Cambrian euarthropod larva”, Smith et al. 2024
https://www.nature.com/articles/s41586-024-07756-8“we describe the internal and external anatomy of a three-dimensionally preserved euarthropod larva with lobopods, midgut glands and a sophisticated head. The architecture of the nervous system informs the early configuration of the euarthropod brain and its associated appendages and sensory organs, clarifying homologies across Panarthropoda.”

Many people think the history of the Earth is hard to decipher. The geological record jumbles everything up. We set out to fact-check this in my ERC Starting Grant MindTheGap. Focusing on the mode of evolution, because that is something that we can only glean from long records, longer than anything accessible to observation or experimentation today.
Thanks to collaboration with Peter Burgess we used forward models to simulate formation of carbonate rocks and see how completeness and stratigraphic resolution affect the reconstructions. Guess what! The geological record is 👌🏻 With a bit of understanding of #sedimentology and #physics we can test is with computer experiments and it turns out even very patchy rock strata will let us reconstruct the correct mode of evolution. This opens a lot of possibilities, especially for the #microfossil community: your data is priceless to understand #microevolution.
Check out the results at https://lnkd.in/eeiSuRwP
Also a big shoutout to an excellent review process at PCI Paleo, the thoughtful editors and reviewers, and to the lead author Niklas Hohmann for #code #reproducibility effort that meets the most stringent standards. Check out our software at https://lnkd.in/eJkwhhuh

It's very satisfying to see the crown article of my first PhD student Bryan Shirley published! Skeleton is usually all that remains from an animal in the fossil record, so in order to find out how the animal functioned when alive, we have to squeeze out clues from the skeletal tissues, for example using advanced #ElectronMicroscopy 🔬. We were told that vertebrate tissues are too chemically unstable to study this way, but with the help of experts in microscopy, we were able to make rapid measurements of crystallography in the oldest #vertebrate hashtag#teeth to understand how they function evolved. Turns out the crystal orientation reflects the function! From the #ultrastructure we can estimate how the animals were biting and see their evolutionary adaptations at the level of individual crystals 💎 This was possible thanks to the facilities and funding by EXCITE network and Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation

By uncovering how species have responded as past climates changed, conservation paleobiologists are helping to understand how the same species may respond to climate change today.
Their results are guiding management plans for some of the world’s most endangered ecosystems.
