New paper from @pichkary@AbigailSearfoss@CreanzaLab on cultural evolution in chipping sparrow song! Really creative application of agent-based modeling to community science data ๐ฆ https://t.co/V1T1KneJ9u
@pichkary@AbigailSearfoss We also found that some chipping sparrow songs were sung by many individuals over a long time period (>50 years) and some were only observed once. The long-lasting songs were sung faster (they were made up of more, shorter syllables) ๐ฆ
Excited to share a publicly accessible link to new work with @pichkary and @AbigailSearfoss -- detecting cultural evolution in songbirds (chipping sparrows!) using community science data and computational modeling https://t.co/n7kkGt0kUD
@pichkary@AbigailSearfoss We simulate chipping sparrows learning from a random neighbor, the most common song, or the fastest song. When we compare our simulated results to real data, it seems like chipping sparrows might try to learn the best song around them!
Our results suggest that past populations might have mated assortatively with speakers of the same dialects or those who shared other other associated cultural features.

Genes and languages have worldwide signatures of human history โ but does variation *within* a language correspond to genetic population structure? @pichkary examined pronunciation of English words and found greater genetic differences at dialect borders: https://t.co/sXBPe9x4oL
We analyzed two separate datasets (https://t.co/Ru7YmZFjGY and https://t.co/V4V96b5v4q)โboth sampled people with multigenerational ties to rural+agricultural locations, so our data are linked to 19th century England, not to more recent movement and mixing
Big congratulations to newly minted Dr. Kerri-Ann Anderson, who successfully defended her PhD and has a new paper out modeling the interactions between vaccine hesitancy and vaccination behaviors! https://t.co/p1SEVhcOmB
How might population contact affect the tools and technologies of a population? Happy to see this paper out, featuring the work of former undergrad Sarah Saxton Strassberg (now a PhD candidate at UChicago!) and wonderful collaborators @YotamBenOren@orenkolodny @ErellaEhovers
What happens when some members of a population have specialized knowledge? Our model predicts that if the population is large enough, their cultural repertoire could expand, but if it is too small, the specialized knowledge could be lost.
