RDNAn analysis of genes associated with responses to burn injuries found that, of 94 total, at least 9 and as many as 19 show positive selection in humans but not in non-human primates. This suggests that human evolution has included adaptive responses to burn injuries.

Surviving Burns May Have Changed Human Evolution
Frequent burn exposure may have driven human genetic adaptations that improve healing but worsen severe injury outcomes. Humans may have been shaped in part by an unexpected force: repeated exposure to high-temperature burn injuries. New research suggests this long history has influenced how the
