Evolutionary Anthropology: "Burn Selection: How Fire Injury Shaped Human Evolution." A new study argues that over a million years of domestic fire use exposed humans to recurring fire burn injury, driving accelerated genetic evolution in our wound-healing…
🔥 The "Burn Selection Hypothesis" suggests that fire mastery led to increased burn risks, driving unique genetic adaptations in humans related to wound healing and inflammation.
🧬 Comparative genomic analysis reveals that genes involved in responding to burn injuries have undergone accelerated evolution in the human lineage, suggesting they were under significant selective pressure.
🩹 These evolutionary adaptations may explain both beneficial responses to burns, like faster healing of smaller injuries, and paradoxical maladaptive responses to severe burns, such as intense inflammation.
