Close up of tree rings under a microscope

Trees are like nature's archives. The annual growth rings of trees 🪵 capture many tree-environment interactions ☀️🌲 that are unique to a particular place and time 🗒️ (1/6)

What Bones from Prehistoric Poland Reveal About Who Ate What — and Why It Mattered A new isotope study tracks three millennia of diet, inequality, and food identity in north-central Poland, from the Neolithic to the Bronze Age.

Bones from prehistoric Poland reveal 3,000 years of dietary shifts: forest-herding Corded Ware nomads, Bronze Age inequalities hidden in nitrogen levels, and millet arriving fast — as cultural identity, not gradual adoption. #Archaeology #IsotopeAnalysis #PrehistoricEurope

Scientists uncover that horsetails generate unique water signatures mimicking meteorites, offering insights into ancient climate decoding via modern and fossilized plants. 🌿🔍 Link: https://tinyurl.com/2b73maw2 #ClimateScience #IsotopeAnalysis #Paleoclimate

How Andean Foragers Became Farmers Without Giving Up the Good Life Stable diets and cultural ingenuity shaped the rise of agriculture in the ancient Titicaca Basin, not desperation or decline

New study of 5,000-year-old Andean diets shows farming didn’t start from famine. Early foragers kept stable, diverse diets as they added crops and camelids. Farming was smart, not desperate. #Andes #Archaeology #HumanEvolution #IsotopeAnalysis @plosone.org

Echoes of the Past: Understanding Ancient Diets at Franchthi Cave Isotopes unravel a 10,000-year story of shifting diets and rituals in the Mediterranean.

Isotope analysis from Franchthi Cave reveals that Mesolithic & Neolithic diets were largely terrestrial, with sporadic use of marine resources, challenging previous assumptions about Mediterranean prehistoric foragers. #IsotopeAnalysis #MediterraneanPrehistory #Anthropology #PrehistoricDiets #CSIA
