Eventually, fire became embedded in human behaviour, so that it is involved in almost all advanced technologies. Rather than as an event, the discovery of fire use may be seen as a set of processes happening over the long term. Early hominins would undoubtedly have been aware of such fires, as are savanna chimpanzees in the present. Birds such as hawks, and some other predators, are alert to opportunities to catch animals including invertebrates disturbed by such fires and similar benefits are likely to underlie the first human involvements with fires. Natural fires caused overwhelmingly by lightning are highly evident on many landscapes. Numbers of animal species react to the natural phenomenon of fire, but only humans have learnt to control it and to make it at will.
