Humans have been hunter-gatherers for 99% of their history.
Hunting and gathering as activities have been with humans for all of human evolution up to today. For more than 99% of their time on earth, humans have gained their sustenance through animal and plant food that they hunted and gathered.
Even so-called “herders” and “farmers” (or “pastoralists” and “agriculturalists” as they are often called) have historically tended to spend some of their time hunting and gathering. Especially in harsh times, for instance when drought threatens domesticated animals or harvests, herders and farmers include hunted game and undomesticated plant foods in their diet.
