Scientific American 202502 Neandertal DNA and the Human Mind Summary

Generated by Codex with GPT 5.6 Sol XHigh

Neandertals were once portrayed as dull evolutionary failures, separated from modern humans by a wide intellectual gulf. Archaeology has steadily erased that caricature. They made sophisticated tools, processed plants into food, treated illness, used symbols and cared for their dead. Then the first Neandertal genome delivered an even more intimate correction in 2010: Neandertals and Homo sapiens interbred, and their DNA still forms part of many living human genomes.

This summary covers The Economist’s July 4th, 2026 Science & technology article listed in the contents as Synthetic biology and published under the headline A design for life.
