They claim that recent evidence suggests how the people who built Stonehenge had abandoned the cultivation of many important crops, and reverted back to gathering for significant aspects of their diet (I think they put a lot of emphasis on hazelnuts if I remember correctly – so they were not 100% hunter-gatherers, no; but they had decided to revert back to more hunting and gathering and to scale down their commitment to agriculture. But they also claim that many scholars staunchly ignore this research/evidence. Why, are they wrong?
