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.

Hard plant foods like seeds and nuts may have made up a larger part of early human ancestors’ diet than currently presumed, according to a new experimental study of modern tooth enamel from anthropologists in Arts & Sciences.

While closely held ownership isn’t necessarily bad, research co-authored by a faculty member at Washington University in St. Louis’ Olin Business School suggests some African firms may miss 21st century growth opportunities without the ability to raise capital through shared ownership.

New Arts & Sciences research finds that chimpanzees that use a multi-step process and complex tools to gather termites are more likely to share tools with novices. The study helps illuminate chimpanzees’ capacity for prosocial — or helping — behavior, a quality that has been recognized for its potential role in the evolution of human cultural abilities.

For thousands of years, goosefoot and knotweed were grown as crops, possibly feeding as many indigenous people of North America as corn. But the domesticated forms of these lost crops became lost over the years, and now a Washington University in St. Louis archaeologist is trying to figure out why — and recreate them.
