"The bones sealed up the marrow like a Tupperware container"

A taste for fat, not meat, may have made us human: A new paper argues that our early ancestors acquired a taste for fat by eating marrow scavenged from the skeletal remains of large animals that had been killed and eaten by other predators. The argument challenges the widely held view among anthropologists that eating meat was the critical factor in setting the stage for the evolution of humans. While focusing on fat over meat may seem like a subtle distinction, the difference is significant. The nutrients of meat and fat are different, as are the technologies required to access them. The authors review evidence that a craving for marrow could have fueled not just a growing brain size, but the quest to go beyond smashing bones with rocks to make more sophisticated tools and to hunt large animals.
