A fossil discovery in South Africa suggests that P. robustus evolved rapidly during a turbulent period of local climate change about 2 million years ago, resulting in anatomical changes that previously were attributed to sex. An international research team including anthropologists at Washington University in St. Louis reported their discovery in Nature Ecology & Evolution on Nov. 9.
It is not easy to conduct human milk research during a pandemic. Yet despite the consistent lack of quality evidence for transmission of viral RNA from breast milk, some leaders are pushing ahead by altering public health and clinical practice guidance, according to E.A. Quinn, associate professor of biological anthropology in Arts & Sciences at Washington University in St. Louis.
Older male rhesus monkeys sire fewer offspring. Sperm quality or quantity, or the survival of infants, may decline with the age of the would-be father, a new study from biological anthropologist Krista Milich in Arts & Sciences suggests.
New research from Washington University in St. Louis provides evidence that Indigenous people continued to live in southeastern U.S. and actively resist European influence for nearly 150 years after the arrival of Spanish explorers in the 1500s.
Undergraduates in the class “Anthropology of Infectious Diseases” in Arts & Sciences presented their findings during a remote symposium held April 22. The event was the last gathering for students in a course that became far more consequential than anyone could have predicted.
New research led by anthropologists at Washington University in St. Louis shows that encounters between gorilla groups were much more frequent, and that they had more varied social exchanges than expected. The effort is part of a long-term collaboration with the Congolese government and Wildlife Conservation Society that is changing perspectives on gorilla behavior, ecology and health.
An international team of researchers that includes anthropologists at Washington University in St. Louis has unearthed the earliest known skull of Homo erectus, the first of our ancestors to be nearly human-like in their anatomy and aspects of their behavior. The effort was led by La Trobe University in Australia.
A noblewoman from Imperial China enjoyed playing polo on donkeys so much she had her steeds buried with her so she could keep doing it in the afterlife, archaeologists found. This discovery by a team that includes archaeologist Fiona Marshall at Washington University in St. Louis is published March 17 in the journal Antiquity.
Genetically modified Bt cotton is the most widely planted cotton crop in India by acreage, and it is hugely controversial. Supporters long touted increased yields and reduced pesticides to justify its pickup. But that argument does not hold up under the first long-term study of Bt cotton impacts in India. The analysis is co-authored by a Washington University in St. Louis anthropologist in the journal Nature Plants.
Heralded as a genetically modified crop with the potential to save millions of lives, Golden Rice has just been approved as safe for human and animal consumption by regulators in the Philippines. But a new study by Glenn Davis Stone, professor of sociocultural anthropology and environmental studies in Arts & Sciences, finds that most families affected by Vitamin A deficiency can’t grow Golden Rice themselves, and most commercial farmers won’t grow it either.
