The domain of fire may also have led to genetic changes that helped early humans survive minor burning injuries, but this evolutionary feature could complicate the treatment of more serious cases today.
An initial stage study suggests that the selection of genes that avoid mortal infections that could arise from minor burns were prioritized early. Homo sapiensBut these same genes interfere with the healing of the serious ones. This may be due to the fact that in primitive times, people with severe burns almost had no hope to survive …
