What did the Vikings eat?

Examining a culture's culinary practices gives insight into its social structure, skills, and ideology. This article follows culinary archaeologist Daniel Serra as he explores the food habits and choices of Vikings. His findings have effectively ended "the myth of Vikings gnawing off the meat of the bones of wild animals," with evidence providing a clearer picture of Viking society as filled with farmers who didn't have time to hunt.

A timeline of human fossil discoveries

A key part of writing a coherent story about our origins is finding and identifying the remains of our ancestors and understanding their significance. Scientists will not always agree on identifications and opinions will change as new find are made and new ways of studying them are developed.

The Paranthropus genus, our mysterious extinct cousins

In the last century, skull and jaw fragments have been discovered in East Africa suggesting an ancient hominin species lived, evolved, and died alongside humanity's ancestors. With large, broad skulls and strong jaws, the Paranthropus genus—which includes several related species—is an absorbing case of the effects of niche partitioning, where species coexist by adapting differently to the environment. Paranthropus died out and human ancestors endured. Find out why here.

A look at what was on the menu for ancient Romans

"Delicious Italy" is a website exploring the food culture of various Italian cities and regions, and in this article, the editors explore what is known about the diet of ancient Romans. Olives (and their oil) were a key daily essential, alongside grains like barley, millet, and spelt flour. Where meat was found it was most often ox, pork, deer, lamb, and even pigeons. Middle Eastern fruits like cherries and peaches could last long enough to travel to Roman cities around the Mediterranean, and candy-friendly dates were sourced from Africa. Explore this and much more at Delicious Italy.

Searching for the history of cancer in ancient human bones

Nestled under archaeology lies bioarchaeology, which involves the study of bones, human or animal. This subfield recently birthed another field of study: paleo-oncology. Paleo-oncology looks for cancer and related biomarkers in bioarchaeological remains. This TED article explains how this nascent multidisciplinary field challenges the idea that cancer is modern.

The Archaic period marked Native Americans' shift from big-game hunting to foraging

Beginning around 8000 B.C.E., Indigenous peoples began relying on diverse food sources—including wild game, plants, seeds, and fish—and moved away from large-mammal hunting. Archaeological findings from this era suggest some communities began cultivating crops and establishing irrigation systems, indicating a shift toward less-nomadic lifestyles.

Neanderthals commonly had surfer's ear, a potential sign of extensive seafood collection

Analysis from 2019 found that about half of the 23 Neanderthal skulls scientists examined seemed to have the bony growths in the inner ear, signifying they had surfer's ear. Those growths suggest our ancient relatives, dating back to between perhaps 100,000 and 40,000 years ago, were potentially hunting fish, mollusks, or other marine resources in chilly waters.

Climate proxies reveal past climate patterns using preserved natural evidence

Scientists use physical, chemical, and biological materials preserved in sediments, ice, and fossils to infer historical climate data. These proxies are studied and calibrated against modern climate conditions to interpret ancient environments accurately.

How do archaeologists determine how old something is?

Genetic analysis suggests Anopheles mosquitoes fed on humans some 1.8 million years ago

The 2026 paper, based on 11 species of Anopheles mosquitoes found in Southeast Asia, suggests that mosquitoes in the region likely developed their human blood preference between 2.9 million and 1.6 million years ago, overlapping with when scientists believe Homo erectus arrived there.
