Four ancient genomes from coastal Ecuador reveal 1,500 years of population continuity, despite a major volcanic eruption and the rise of maritime and overland trade. One infant from 2,300 years ago shows skeletal signs of tuberculosis. In @PNASNexus: ow.ly/BpJ95102vM5

Around 14–15 million years ago, during a cool, arid period, forests in Northwest Africa turned into C3 grasslands, according to a study of plant waxes. The modern savanna, dominated by grasses using the C4 photosystem, appeared in the late Miocene: ow.ly/hcPJ50ZzW7s

Did you know your #DNAMethylation continues to change after death? A new forensic study tracked how #decomposition affects epigenetic patterns in pigs, and showed they may help estimate: post-mortem interval, age, and sex. 🕒 📅 ⚧ More in #JFS article: doi.org/10.1111/1556-4029.70…

In 9 of 13 brain regions, volume differences between two living human groups were larger than the estimated differences between Neanderthals and early Homo sapiens. @PNASNews doi.org/hbzqgq sciencex.com/news/2026-04-ca…

Malaria was fundamental in shaping the course of human evolution, @CamZoology researchers have found. From 74,000 to 5,000 years ago, early humans in Africa did not live in high-risk malaria areas. This shaped how populations met and mixed, leading to the population structure seen today.

La “sífilis más antigua” en Bogotá, de 5.500 años. Eso publicamos todos. Sonó histórico. Pero hay un detalle: hace más de 50 años, científicos colombianos ya habían contado esa historia. Y los olvidaron🧵👇 Les cuento en @elespectador elespectador.com/salud/cient…

El Instituto Humboldt, junto a @El_Icanh y la comunidad, identificó una cueva en Santander que tiene arte rupestre en su interior. Este hallazgo es un hito para la arqueología y la biodiversidad, pues es la primera de este tipo en el país. | @classoalcala humboldt.org.co/noticias/des…
