Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).
Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study published in the journalon August 18 analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period .
Scientists have known that the fats preserved in ancient pottery and the proteins from dental calculus -- the hard mineralized plaque deposits on the teeth -- contain traces of the proteins ancient people consumed during their lives. Now, this study combines protein analysis with archaeology to explore specific details about the meals cooked in these particular vessels. Many metal alloys have antimicrobial properties, which is why the proteins have been preserved so well on the cauldrons.
The researchers collected eight residue samples from seven cauldrons that were recovered from burial sites in the Caucasus region. This region sits between the Caspian and Black Seas spanning from Southwestern Russia to Turkey and includes the present-day countries Georgia, Azerbaijan, and Armenia. They successfully retrieved proteins from blood, muscle tissue, and milk. One of these proteins, heat shock protein beta-1, indicates that the cauldrons were used to cook deer or bovine tissues.
Although the cauldrons show signs of wear and tear from use, they also show signs of extensive repair. This suggests that they were valuable, requiring great skill to make and acting as important symbols of wealth or social position -- perhaps a little like Le Creuset or Mauviel saucepans today.

Key role of ice age cycles in early human interbreeding -- ScienceDailyRecent paleogenomic research revealed that interbreeding was common among early human species. However, little was known about when, where, and how often this hominin interbreeding took place. Using paleoanthropological evidence, genetic data, and supercomputer simulations of past climate, a team of international researchers has found that interglacial climates and corresponding shifts in vegetation created common habitats for Neanderthals and Denisovans, increasing their chances for interbreeding and gene flow in parts of Europe and central Asia.

Race-based variations in gut bacteria emerge by 3 months of age -- ScienceDailyEarly social and environmental exposures can have large and lasting effects on child development and adult health. One of the systems that is vulnerable to external influence is the gut microbiome. A new study highlights a critical development window during which racial differences in the gut microbiome emerge. The findings are based on analysis of data from 2,756 gut microbiome samples from 729 U.S. children between birth and 12 years of age.
