AI Summary

The discovery suggests that ancient humans may have developed a unique adaptation to survive the last ice age. This adaptation could have allowed them to thrive in environments that were previously inhospitable. The proposed mechanism involves a genetic variation that may have enabled early humans to conserve energy by reducing their metabolic rate. This could have been crucial for their survival in a time when food was scarce and harsh conditions prevailed. The findings are based on a study that analyzed the genetic data of ancient human remains. The results indicate that this adaptation may have been more widespread than previously thought, with evidence found in multiple human populations.
