When Did Neanderthals And Humans Interbreed Popular Science While pop culture often depicts our ancestors rubbing two sticks together in caves, new findings suggest that neanderthals were using a smart chemistry hack to fuel their fires 50,000 years ago. Now, a study has revealed the archaic humans used stone tools to create their own fires just like their modern human counterparts, scientists reported in the journal scientific reports.

Neanderthals Used A Chemistry Trick To Start Fires 50 000 Yea A 2016 study suggested neanderthals used powdered magnesium dioxide as a fire lighter, and a 2018 study led by sorensen proposed that distinctive marks on neanderthal tools from around 50,000 years ago were evidence of fire making. the new technique could also help determine if the use of fire arose more than once. The first step to re creating 50,000 year old technology is to collect a bunch of rocks. so began andrew sorensen’s plan to study a great mystery in archaeology: how neanderthals controlled fire. When they sprinkled that powder on a pile of wood, it lowered the temperature needed to initiate combustion to 250°c, making it much easier to start a fire, they report today in scientific reports. (untreated wood failed to ignite at temperatures up to 350°c.) the researchers can't rule out other possible neandertal uses for manganese dioxide. This tar handled tool was made by a neanderthal 50,000 years ago. the tar, preserved by the cold, oxygen free conditions in sediments several meters beneath the sea floor, might have been an essential element of stone age tool kits, says co author geeske langejans, an archaeologist at the delft university of technology in the netherlands.
