Our new paper on reassessing the heritability of human lifespan is out in @ScienceMagazine! 🧬
For decades, the consensus has been that genetics explains just 20–25% of lifespan differences. We found that after accounting for extrinsic mortality, that number jumps to ~50%.
A 🧵 Image The classic 20-25% estimate comes from a Danish study on twins born 1870-1900. By comparing the similarities in lifespans between identical and non-identical twins, one can get a handle on heritability. Image
