So proud of @rachel-hurwitz.bsky.social for publishing her 1st PhD chapter 💪 check it out! It’s a really cool review on how can extant primates can help us to identify tool use in the past 🦴🙂
New article out in Evolutionary Anthropology! onlinelibrary.wiley.com/doi/epdf/10....
Check out our new paper on Pliobates! Really cool fossil and results 💪🦴 congrats to all the team 😀 rdcu.be/fuc8u 🐒 led by @julsam.bsky.social
Paper alert👏🤩 Our work on the distal humerus of Pliobates was just published in JME. Thanks and congrats also to Ambra Figueroa-Torrejón, @tpuschel.bsky.social, @a-urciuoli.bsky.social, S Almécija, G Raventós-Izard and DM Alba. Featuring lovely artwork by @gamarraptor.bsky.social! rdcu.be/fuc8u

How humans evolved to be twice as big as our ancestors | New Scientist
Artistic representations of ancient humans often show large men with bulging muscles – but our ancestors were actually smaller than us, in both height and body mass. Columnist Michael Marshall reveals...

Hominins got larger over time, according to an analysis of 386 specimens across 21 taxa. There’s strong evidence for a marked body mass increase for all late Homo species, except Homo habilis. In PNAS: https://ow.ly/LopK50Zh9S6

Human Ancestors Suddenly Got Bigger Around 2 Million Years Ago — With Average Body Size Jumping From 88 to 132 Pounds
Learn how fossils show human ancestors did not grow bigger in a straight line, but split into larger and smaller evolutionary paths.

Loved being part of this study! We investigated how body size changed through time in human evolution, finding a moderate general increase among all hominins and a marked jump in later Homo. www.pnas.org/doi/10.1073/... @pnas.org @ox.ac.uk @oxford-anthro.bsky.social @uniofreading.bsky.social

Why Is Nearly Every Person Right-Handed—but Not Every Ape and Monkey? New Research Explores the Evolutionary Origins of Human Handedness
Brain size and bipedalism are the most likely drivers of our species’ right-hand dominance, according to new research
smithsonianmag.com
90% of people are right-handed, and no other primate species comes close to this level of hand preference. A new Oxford-led study suggests the reason may lie in two defining features of human evolution: walking on two legs and the expansion of the human brain. More info ⬇️ https://bit.ly/42Cbvnc
We use data from ~2,000 individuals and 41 species to show that factors such as encephalization and bipedalism explain why at population level we are so predominantly right-handed (no other primate species shows it this strongly) www.ox.ac.uk/news/2026-05... @oxford-anthro.bsky.social @ox.ac.uk
Why is almost everyone right-handed? The answer may lie in how we learned to walk
Humans are the only primates with a population-wide hand preference. A new Oxford-led study, 'Bipedalism and brain expansion explain human handedness', published in PLOS Biology, traces it back to bip...

Thrilled this paper is out! We describe the rich vertebrate fauna from Lomekwi, identifying 85 taxa. During the time of Kenyanthropus, there were megaherbivores 🦒🦛🐘, numerous artiodactyls, diverse carnivores, giant crocodiles, and multiple primates 👉 authors.elsevier.com/c/1mHna3ic-F...

Early primates evolved in cold, seasonal climates, not warm tropical forests - new research by our Associate Professor in Evolutionary Anthropology, Dr Thomas Püschel, and collaborators @uniofreading.bsky.social challenges our assumptions about where primates originated: https://shorturl.at/3AnbC
Fossil and environmental data indicate that early primates evolved in cold, seasonal climates in North America, challenging the long-standing view that they originated in tropical forests. doi.org/g9v72t
Fossil evidence reveals early primates evolved in cold climates, not tropical forests
Primates—the group of animals that includes monkeys, apes and humans—first evolved in cold, seasonal climates around 66 million years ago, not in the warm tropical forests scientists previously believed.
