Fire in the root of humans (2)

January 16th, 2016 Leave a comment Go to comments

Many people have the idea that fires scare animals and fled them in panic. However this is not always true, some species react still and calm and move away to safe sites. Some time ago I mentioned a study demonstrating that chimps in wild, when they see a wildfire, they react calmly, predict their behaviour and move accordantly without any stress or fear, suggesting that they have some understanding of fire behaviour [1]. Few days ago I came across other studies [2,3] suggesting that different species of primates not only react calmly to fire but after a fire, they increase their home range to include the area burned and used it for searching food, including 'cooked' fruits! So wildfires were very important in the history of humans [4], they could have contribute to the first step towards humanity from our ancestors ...
