Two fake accounts impersonating me appeared recently and sent messages to many of my contacts. They used slightly incomplete versions of my name. Thanks so much to everyone who spotted and reported them. Both accounts have now been removed. Several other R users on Mastodon have had similar […]

As far as we know, such a comprehensive analysis conducted within a single Bayesian framework has never before been attempted, and marks a significant methodological milestone for the study of cultural evolution. Given this innovative approach, we placed […] [Original post on mastodon.social]

We also used skyline analysis to examine birth, death, diversification, and turnover rates across the four major climatic warming and cooling events during this timeframe, based on the Greenland ice-core event stratigraphy.

We used a fossilized birth-death sampling process model to infer time-scaled Bayesian phylogenies, utilizing the projectile point outline shape as continuous characters (first use of this in archaeology that we are aware of).

New paper! Lead by David Matzig, we used a state-of-the-art Bayesian phylodynamic framework to explore the evolution of projectile point shapes during the European Final Palaeolithic and earliest Mesolithic (approximately 15-11ka BP). doi.org/10.1098/rsos.240321
