ATH 101 Intro to Biologic Anthropology: Get Started

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.

Humans' unique language capacity was present at least 135,000 years ago, according to a survey of genomic evidence. As such, language might have entered social use 100,000 years ago.

Researchers have identified the economic and political borders separating El Argar, considered to be the first state-society in the Iberian Peninsula, from its La Mancha and Valencia Bronze Age neighbors some 4,000 years ago. These communities, with less centralized social structures, maintained complex relations with the Argaric culture. The study, based on an innovative analysis of pottery production and circulation, opens the door to identifying similar border dynamics in other European societies contemporary to El Argar, and understand how the first states were formed in prehistory.

The discovery of a human facial fragment aged over one million years represents the oldest known face in western Europe and confirms the region was inhabited by two species of human during the early Pleistocene, finds a new study.

For more than 140 years, Mixodectes pungens, a species of small mammal that inhabited western North America in the early Paleocene, was a mystery. What little was known about them had been mostly gleaned from analyzing fossilized teeth and jawbone fragments. But a new study of the most complete skeleton of the species known to exist has answered many questions about the enigmatic critter -- first described in 1883 by famed paleontologist Edward Drinker Cope -- providing a better understanding of its anatomy, behavior, diet, and position in the Tree of Life.

Without plants on land, humans could not live on Earth. From mosses to ferns to grasses to trees, plants are our food, fodder and timber. All this diversity emerged from an algal ancestor that conquered land long ago. The success of land plants is surprising because it is a challenging habitat. On land, rapid shifts in environmental conditions lead to stress, and plants have developed an elaborate molecular machinery for sensing and responding. Now, a research team has compared algae and plants that span 600 million years of independent evolution and pinpointed a shared stress response network using advanced bioinformatic methods.

Researchers have discovered the world's oldest known meteorite impact crater, which could significantly redefine our understanding of the origins of life and how our planet was shaped. The team found evidence of a major meteorite impact 3.5 billion years ago.

The oldest collection of mass-produced prehistoric bone tools reveal that human ancestors were likely capable of more advanced abstract reasoning one million years earlier than thought, finds a new study.
