It took a lot of fat and protein to survive during the Last Ice Age. Researchers explore if early humans scavenged animals and if it contributed to their development.
Saber-tooth cats ate only a portion of what they killed, creating opportunities for other species. When early humans first arrived in modern-day Spain, about a million and a half years ago, they immediately faced a quandary: what to eat?
But have no fear. A new computer simulation has found that with sufficient numbers, human groups could have scavenged enough meat to sustain a healthy population. There’s only one catch: To really excel at scavenging, they would have had to scare off the occasional hyena and take a kill by force.
Per the simulation, more than 10 humans were enough to shoo away any of the predators, and thus the researchers found that a population of about a dozen hit the sweet spot. Beyond that, the negatives of adding more people exceeded the positives. Carrion bones may also have stimulated technological development as early humans fashioned them into tools such as multi-purpose “retouchers” used to sharpen stone edges.
