In our new paper we discuss the coevolution of cognition and sociality (link: royalsocietypublishing.org/doi/10.1098/...). It was a pleasure to work on this project with Andoni Sergiou, @josharbon.bsky.social, @inesfuertbauer.bsky.social, @shoalgroup.bsky.social, and @cornishjackdaws.bsky.social!

New paper!
We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-series—that is, without the need to aggregate them over time.

Social relationships are powerful predictors of fitness across social animals. But *why*?
In our new @cp-trendsecolevo.bsky.social paper, we outline testable predictions for why relationship quality and quantity adaptively vary across socio-ecological contexts.
