Fascinating synthesis examining uncertainty reduction as a primary reinforcer across behavioural domains. Explains the role of cortico-cerebellar loops in cross-domain sequence processing. A fundamental role for curiosity in natural behaviour. 4087/2/3/10.20935/AcadNeurosci8451

Uncertainty reduction as a candidate primary reinforcer: an evolutionary and neural account
This integrative review proposes that the reduction in uncertainty may function as a candidate primary reinforcer in humans. The proposed mechanism is positive prediction error coding by the mesolimbi...

“modular evolution of neocortical size in primates is closely linked to the evolution of the visual system” (i.e., “enhanced visual processing, not expansion of the frontal lobe, drove the major increases in neocortical size”) 🧪🧠 www.science.org/doi/10.1126/...

Neocortical expansion is a key innovation of crown primates, although fossil evidence for how the neocortex has evolved remains elusive. We studied neocortical evolution using virtual brain endocasts ...

A small contribution to an important topic, in Nature Reviews Biodiversity. I highlight @howbrainsevolve.bsky.social and Harvey's work in 2000 and illustrate it's pivotal role in our understanding into the principles of brain evolution. Have a read - it's short! www.nature.com/articles/s44...

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
010
howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 13/01/2026
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
110
howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 13/01/2026
We then show that this pattern is a metaphenomenon arising from a pattern of diminishing allometry within species with increasing size

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

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...

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 🙏🏻

On brain size? I thought the point being addressed here is what is the allometric relationship between brain and body size?

howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 10/06/2025
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

Plotting regressions without regard to phylogeny - as in the older literature - is the more general issue.

howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 09/06/2025
To me, the concept of a ‘system’ implies selection. That’s how the appearance of design happens and why we can talk about function. But in practice it’s very complicated with lots of genes and lots of aspects of the phenotype - so agree with your point, ‘targets’ are hard to specify
010
howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 09/06/2025
Suspect Steve’s point is that our paper (he cites above) reveals nonlinear scaling even in log-log space, and doesn’t support the conclusions of the paoer Mauricio cited, nor specifically a power law of 0.75

Precisely
120
howbrainsevolve.bsky.social @howbrainsevolve.bsky.social · 09/06/2025
Or selection on neural systems has consequences for brain size - brain size as an outcome rather than a target of selection

“males invest more on locomotor control, flight stability and sky-compass navigation which may have evolved in response to sex-specific behaviours, like courtship display…females have larger mushroom bodies that strongly and positively covary with the optic lobes…” Lovely work!

I made this slide during his first presidency. It illustrates how not to make evolutionary inferences from comparative data (dashed red line, although that could also be stock markets). Today more than ever it seems like an insult to chimpanzees
