Have you ever heard an opera singing ape? Researchers in Japan have discovered that singing gibbons use the same vocal techniques as professional soprano singers. The study, published in the American Journal of Physical Anthropology, explains how recording gibbons singing under the influence of helium gas reveals a physiological similarity to human voices.
Salt beef, sea biscuits and the occasional weevil; the food endured by sailors during the Napoleonic wars is seldom imagined to be appealing. Now a new chemical analysis technique has allowed archaeologists to find out just how dour the diet of Georgian sailors really was. The team’s findings, published in the American Journal of Physical Anthropology also reveal how little had changed for sailors in the 200 years between the Elizabethan and Georgian eras.
In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia.
Genetic Diversity of Native Americans: New Research finds evidence in genes for both prehistoric migrations and environmental adaptations.
For many years, anthropologists have asked who the first Americans were, and how they were able to settle the last major habitat open to humans. Now, a special section of the American Journal of Physical Anthropology features six new papers that use genetics to answer these questions. The findings reported confirm that genetic diversity in contemporary Native Americans bears signatures of the past. The authors find evidence in genes for both prehistoric migrations and adaptations to the new environment. These papers contribute new findings related to distinct phases in the evolution of Native Americans.
