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
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

Shaista Khaliq researches how animals, plants & parasites interact in #ecosystems at the #UDE `s #ZWU. She uses #isotopeanalysis to track nutrient flows & parasite-host relationships. In our #whyidoresearch series, she talks about the highs and lows of her research. www.uni-due.de/2025-01-30-w...
Sharepic: Portrait picture of Shaista Khaliq ( (c) UDE/Schumann) on the left. On the right text: At the Intersection of Instrumental Chemistry and Biology. Sharepic with text on the left: Shaista Khaliq uses isotope analysis to investigate where organisms obtain their nutrients and how parasites influence their hosts. On the right a picture, which shows a stickleback with text underneath: In a study, Khaliq shows that tapeworms significantly affect sticklebacks, with isotope analyses revealing significant changes in the liver. Sharepic with text: Using compound-specific isotope analysis and high-precision instruments, I reveal the hidden signatures of substances by developing and optimising analytical methods. Sharepic with text: The path to a career in science is often challenging, with many ups and downs. It’s important to be patient with yourself and to recognise that negative results are a valid and valuable part of the research process. Shaista Khaliq Instrumental Analytical Chemistry
