Ancient DNA Reveals How American Bison Survived Near-Extinction and Were Managed by Indigenous Peoples
Key Takeaways
- Study published in Science reveals bison experienced a severe population bottleneck ~30,000 years ago, losing up to 90% genetic diversity.
- Genomic analysis shows recovery began ~15,000 years ago, with regional genetic differentiation.
- Indigenous peoples actively managed bison through controlled burns and selective hunting, influencing their genetics.
- Modern conservation can use this data to restore genetic diversity and integrate traditional ecological knowledge.
