"Unearthing 12,000-Year-Old Preserved Human Brains Challenges Decay Theories"

A team of scientists at Oxford University has discovered that human brains can preserve quite well, challenging the long-held belief that they quickly decompose after death. Through an analysis of over 4,000 human brains dating back 12,000 years, the researchers identified five distinct preservation methods, including saponification, freezing, tanning, dehydration, and an unknown category. The study suggests that local environmental conditions play a significant role in brain preservation, and it raises questions about how nearly a third of the brains have lasted as long as they have.
