Thank you Max!

One implication is that measures of relative brain size should be treated with extreme caution. The curvilinear pattern across species may, for example, explain why large bodied species have been though to be relatively small brained when using linear models to characterise and account for scaling
This has implications for how we interpret macroevolutionary patterns more generally, emphasising the need to account for intraspecific variation in order to understand variation across species
We then show that this pattern is a metaphenomenon arising from a pattern of diminishing allometry within species with increasing size
We were very surprised at how consistent this is across the tree of life
In our new paper, we find that this curve is universal (or very nearly, with a few minor exceptions) including not just homeothermic vertebrates, but also fish, amphibians, squamates and even insects
This has substantial implications for understanding the evolution of brain size
We previously found that the scaling of brain to body mass in mammals is not, as assumed for the past 100 years, log-linear. It is curved: www.nature.com/articles/s41...
Macroevolutionary brain scaling is a microevolutionary metaphenomenon - full text of our new paper now available www.nature.com/articles/s41...

Good luck! 🤞
@royalsociety.org MUST strip Musk of his fellowship to retain credibility. He has brought the society into disrepute in the gravest manner. Calling on all FRSs, please act swiftly
New paper: Human dexterity and brains evolved hand in hand www.nature.com/articles/s42...
A new study co-authored by @howbrainsevolve.bsky.social gives new insight into how human hands & minds evolved together. The research is published in Communications Biology & was led by Dr Joanna Baker of @uniofreading.bsky.social. Read more:👉 bit.ly/4myXT4c

Delighted to see this work out in PNAS. The idea that got me into butterflies, started on it in 2011 but took the intellectual energy of @benitoexplains.bsky.social, and the support of a great team, to develop it and put it all together.
Thanks to #NERC @ukri.org for funding 🙏🏻
Humans may not have a uniquely specialised memory for sequences - it may be more to do with how tasks are culturally scaffolded and what they “mean” to participants. New paper
Interesting new study demonstrates "cerebellar connectivity to higher-order networks at birth, which generally strengthen with age, emphasizing the cerebellum’s early role in cognitive processing beyond sensory and motor functions" www.nature.com/articles/s41...
Interesting new @medrxivpreprint.bsky.social study, bearing on the interpretation of GWAS results:

Interesting Science Advances
study probing the genetics of
human brain geometry (beyond volume), using data from @ukbiobank.bsky.social 🧪🧠🧬
I think “mechanistic” is being used in different senses here
On brain size? I thought the point being addressed here is what is the allometric relationship between brain and body size?
We did account for model complexity in our model testing. A quadratic model fit the data significantly better )not just better). The size dependency in the parameters from linear models is a very striking feature . This is all explained in the paper and SI
