Executive Summary
AI-generatedResearchers in the Yukon have utilized fossilized scat, or coprolites, found in permafrost to reconstruct a rich and diverse ancient ecosystem spanning nearly 700,000 years. These findings, primarily sourced from Arctic ground squirrels' burrows, reveal genetic evidence of various species including mammoths, bison, horses, and large predators. The study highlights the importance of these scat samples as natural archives of past life in the region.

Key Insights
- Fossilized coprolites found in Yukon permafrost provide a unique source for reconstructing ancient genetic information.
- The research focuses on Arctic ground squirrels, whose burrows contain accumulated food reserves and excrements over time.
- Analysis of the scat revealed biodiversity including micro-organisms, plant groups, and animals like mammoths, bison, horses, and large felines.
- Genetic data allowed scientists to reconstruct mitochondrial genomes for species such as ground squirrels (dating back 700,000 years), horses, and bison.
- The findings underscore the ecological richness of the Yukon during the glacial period and the role of permafrost as a natural archive.
