Everyone carries a different piece of Neanderthal DNA:
- All of us have 2-5% Neanderthal DNA, but it's a different 2-5%
- Mine could be heart, liver, skeleton and spleen. Yours could be any other constellation
- Collect every Neanderthal fragment from people alive today and you rebuild more than 90%, possibly more than 95%, of the Neanderthal genome
- Almost none of it was maladaptive. Nearly all of it still passes on and lives in healthy humans
