ANCESTRY AND POPULATIONS Clarifying concepts for inferences about human demographic histories

ROADMAP OF THE TALK 01 Latest developments about human origins (focus on genetic models) 02 Ancestry and Populations: scientific concepts and philosophical focus 03 Taxonomy of populations concepts 04 Application of the taxonomy

CONCLUSIONS Concepts and research practices: "Ancestry" and "populations" need to be clearly defined. Expanding the philosophical analysis: A taxonomy of different population concepts in the modelling stages of population genetics Possible applications: model misspecification, model equifinality and ethical issues when inferring ancestry and population histories

Great talk by our #PhiGeo member @matildecarrera.bsky.social on "Ancestry & Populations: Clarifying concepts for inferences about human demographic histories" at @ishpssb2025.bsky.social

Among the most consequential projects in the history of Earth science was the 1957-1958 International Geophysical Year (IGY), a crash program to study the planet through worldwide collaboration. In the midst of the Cold War and global decolonization, tens of thousands of scientists and citizen volunteers from East and West, North and South, crossed political and ideological lines for the IGY. What they discovered shapes much of what we know about our common planetary home today. March 24, 2025 12:00 PM - 1:15 PM 121 Bay State Road Register here BU Boston University Frederick S.

"It's an amazing achievement ...You have in your hands a piece of ice that is a million years old ....There is a lot of the past in our future. We look at the past to understand better how the climate works and how can we project it into the future" #phigeo ⚒️ 🧪 #philsci

Thank you to my co-symposiasts Carlos Santana & Meghan Page for their fantastic talks, Lydia Patton for inviting us to do a session on #phigeo at #APAEastern25, & @mattbrewer.bsky.social for moderating! #philsci #philsky

⏰ Early bird registration discount for American Philosophical Association’s Eastern Division meeting in NYC expires tonight, December 15, at 11:59 p.m.ET #philsky

I'll be speaking Wed on philosophy of geologic time in session on #PhiGeo #philsci & Friday on @psa-upss.bsky.social Mentoring Program

A v. cool case of data rescue & another reason #histsci & #archives are so important (discussed in my #phigeo book)...
Talke et al. (2018). Relative sea level, tides, & extreme water levels in Boston harbor 1825 to 2018. J. of Geophys. Research: Oceans, 123, 3895–3914. doi.org/10.1029/2017...

My most geophilosophic thought at this moment is that geology is too important to be left to geologists. #phigeo

The tags I have been using are #phigeo #histgeo & #hpgeo (for both history & philosophy of geosciences)

There is not yet a History & Philosophy of Geosciences topic feed to pick them up, but hopefully soon. 😊

Looking forward to participating in an Invited Symposium on Philosophy of the Geosciences at the Eastern APA next month with #philsci Carlos Gray Santana & Meghan Page. #philsky #phigeo

Adding some new tags to Bsky #hpgeo #phigeo #histgeo (in hopes there will be a History & Philosophy of Geosciences feed some day...)
