The new annual review from Kay Behrensmeyer has a killer Figure 3 depicting how different samples of the geologic record equates to different samples of stratigraphic time.

The Neanderthal Garden: Landscape Engineering and the End of the "Pristine Wilderness" Myth By Seth Chagi World of Paleoanthropology

Nice feature on our recent work on neandertals (led by @nikulinaav.bsky.social) and their effects on their environment👣 deephistory.substack.com/p/the-neande... #neandertal #neanderthal #archaeology #anthropology #wilderness

On the ecological impact of prehistoric hunter-gatherers in Europe: Early Holocene (Mesolithic) and Last Interglacial (Neanderthal) foragers compared Recent studies have highlighted evidence of human impact on landscapes dating back to the Late Pleistocene–long before the advent of agriculture. Quantifying the extent of vegetation transformations b...

🔥Before farming, hunter-gatherers already transformed nearly half of Europe’s #landscapes via burning and hunting!
Our new study using an #AI approach shows #Neanderthals began reshaping ecosystems; later foragers continued this process

1️⃣ Not all squirrels are generalists.
Many species are biome specialists, restricted to a single habitat (rainforest, steppe, etc.)

Palaeoverse Lecture Series: Dr. Juan Cantalapiedra - Mammals as a key to evolutionary theory YouTube video by Palaeoverse

Last Thursday @palaeoverse.bsky.social I shared some of our recent projects, exploring the application of phylogenetic methods and the exciting new wave of Bayesian diversification models.

1/ Large herbivores (like ancient elephants, rhinos, deer) aren’t just big plant-eaters—they’re ecosystem engineers. They shape landscapes, disperse seeds, and influence soil and fire dynamics.
But how did they evolve as climates and continents shifted?

Evolution is coupled with branching across many granularities of life | Proceedings of the Royal Society B: Biological Sciences Across many scales of life, the rate of evolutionary change is often accelerated at the time when one lineage splits into two. The emergence of novel protein function can be facilitated by gene duplication (neofunctionalization); rapid morphological ...

Douglas et al. shows that up to 99% of evolutionary change occur at branching points across genes, morphology, and language. A major step for punctuated evolution, aligning with our goal of a unified framework. @nilese.bsky.social @andrejpaleo.bsky.social #EvoBio #CultEvo doi.org/10.1098/rspb...

Just purchased a compilation of Darwin’s writings that did not make it into The Origin. His initial plan was to publish a larger book called Natural Selection. Then he rushed to deliver a shorter version (his most famous book). Some suggest it contains hints of multilevel selection…

Este lunes 19, en La Botillería, hablaré de Darwin y del papel de la paleobiología en redefinir nuestra comprensión de la evolución

After careful examination, we concluded that brontothere horns could have functioned exaptively as towel holders, had they survived into the Anthropocene…

During our visit, we combined analogical and digital approaches…
