We are excited to share our latest article which came out today in @AJHGNews! In this study we investigate genetic factors involved in preeclampsia (a severe complication of pregnancy) in a sample of Andean families 👪 from the Peruvian highlands🏔️ 1/n 🧵sciencedirect.com/science/articl… @AJHGNews Why does this matter? Preeclampsia is a hypertensive complication of pregnancy that affects pregnant parents, esp. women, & their families worldwide 🤰🏻👩🏾‍🍼🤱🏽🫄🏻🌎. Its a major cause of premature birth, as well as maternal  morbidity & mortality. 2/n figo.org/figo-releases-…

Thx for having me @kstsosie @DecolonizeDNA! Today I will tweet about how ancient DNA (aDNA) 💀🧬can be used to revisit the historical record, & reconsider the stories of underrep & minoritized communities across the Americas 🧵1/ #DecolonizeDNA #DNADay (Img: Systema Solar) Image aDNA is the🧬that persists in ancient tissues like 🦷🦴💀, or the remains of 🦌🌿🐀🐚. It can inform us about evolution, ancient diversity & health. But bc of its age, aDNA is degraded and easily contaminated so we must handle it using lots of PPE, like this! 2/ #DecolonizeDNA Image

I am very excited to share our preprint "Ancient DNA reconstructs the genetic legacies of pre-contact Puerto Rico communities”. With contributions by an interdisciplinary team including @StoneLab_ASU @AWRgenes @Conydelafc @DNATimeTravel @cdbustamante 1/n biorxiv.org/content/10.110… @StoneLab_ASU @AWRgenes @Conydelafc @DNATimeTravel @cdbustamante Here we use aDNA to examine the genetic 🧬diversity of ancient Indigenous communities who inhabited 🇵🇷 before European contact. I want to share my thoughts on why our work is important, both for me personally, and for Caribbean anthropology more broadly 2/n
