* Deer are abundant: Deer have been a common and widespread prey animal throughout human history.
* Nutritional value: Deer provide a good source of protein, fat, and other nutrients essential for survival.
* Hunting evidence: Archeological evidence, such as tools and bone fragments, suggests early humans hunted deer. This evidence dates back thousands of years, showing a long history of human-deer interactions.
* Similar species: Early humans likely hunted and consumed other similar prey animals like antelope, gazelle, and wild pigs.
While it's impossible to know for certain what every early human ate, the evidence strongly suggests that deer were a significant part of their diet.
