Humans may have been shaped in part by repeated exposure to high-temperature burn injuries. Research suggests man's long history with fire influenced how the body repairs damage, responds to infection, and reacts under severe trauma.

Humans experience burns, and survive them, far more often than other animals. While most species instinctively avoid fire, humans have integrated it into daily life. As a result, minor burns are common for most people.

The findings suggest that humans developed genetic traits that differ from other primates and mammals, influencing how the body handles both mild and severe burn injuries.
