A statistical fix for archaeology's dating problem

Archaeologists have developed a new statistical approach to overcome the challenges of radiocarbon dating, allowing for more accurate population estimates. The new method uses Bayesian reasoning and flexible probability models to combine radiocarbon dates with additional archaeological information.

Neanderthal genes tell us about how old our ancestors were when they had children

A new study using Neanderthal fragments suggests that generation intervals have fluctuated over the past 40,000 years, with human life history changing in response to environmental and cultural factors. The research found that Eurasian populations reproduced at a younger age than those in Europe, indicating a difference of 3-5 years in...

New archaeological discoveries highlight lack of protections for submerged Indigenous sites

A new study highlights the need for a national policy to protect submerged Indigenous sites, which are at risk due to climate change, dredging, and seabed mining. Archaeological discoveries off the Pilbara coastline in Western Australia have uncovered ancient stone tools, rock art, and engravings dating back over 7,000 years.

Scientists dig deep to understand the effects of population pressure on violence levels

Researchers found a positive correlation between population pressure and higher levels of violence during the Middle Yayoi period in northern Kyushu, Japan. Despite peak population pressures in some regions, lower frequency-of-violence values were observed, suggesting other factors may have influenced violence levels.

Ancient Islamic tombs cluster like galaxies

A study published in PLOS ONE reveals that ancient Islamic tombs in Sudan are distributed according to large-scale environmental factors and small-scale social factors. The tombs cluster around central 'parent' points, likely representing older tombs of importance, with smaller scale distribution influenced by nearby older structures.

Prehistoric homes would have failed modern air quality tests

Domestic burning of wood and dung fuels in Neolithic homes would have exceeded modern internationally-agreed standards for indoor air quality, exposing inhabitants to unsafe levels of particulates. The study suggests that chronic exposure to PM2.5 could be linked to bone lesions found in the remains of Çatalhöyük's inhabitants.

Fossils of "giant cloud rats" discovered in Philippine caves

Scientists have discovered fossils of three new species of giant cloud rats in Philippine caves, dating back tens of thousands of years. The rodents filled an ecological role similar to that of squirrels in the US and were resilient for at least 60,000 years, but two of the species disappeared around 2,000 years ago.

What does the study of domesticated birds tell us about the evolution of human language?

Research suggests that tolerance, cooperation, and reduced aggression in domesticated birds are linked to increased language complexity in humans. The study analyzed genomic, neurobiological differences between domesticated Bengalese finch and its wild relative, finding altered stress hormone balance and brain connectivity patterns.
