Examples similar to humans are, of course, primitive species that once existed, such as the extinct Neanderthals. However, on the fossil teeth of Neanderthals found in France, obvious traces of cooking food with fire have been found-some starch particles remain in the gaps of teeth, and these starches have typical traces of cracking after heating, which is absolute evidence that Neanderthals cooked food with fire.
Of course, we can say that Neanderthal was also a human being, although he was actually a different species from Homo sapiens. But another example is enough to show that cooking food with fire is not a patent for people.
In Australia, raging wildfires often give firefighters a headache, but while firefighters try their best to put out the fire, three kinds of birds are trying their best to spread the fire even more: three kinds of birds of prey, namely Milvus migrans, Haliastur sphenurus and Falco berigora, are found, and they will catch the burnt ones with their mouths or claws.
The purpose of this is to burn insects and animals that have escaped from the grass with the help of fire, so that they can enjoy success.
In fact, in the legends of primitive aborigines in Australia, people learned to use fire by observing the behavior of birds, and these three birds are probably the prototypes of these legends.
