However, not many researchers insist on the occurrence of actual battles as there was little development in weapons compared to the previous generation, especially very few weapons for close combat are found apart from burial goods and few human bones with trauma were excavated.
しかしながら、前代に比べて武器の発達が見られず、特に近接武器が副葬品以外ではほとんど認められないこと、受傷人骨の少なさなどから、具体的な戦闘が頻発していたと主張する研究者はあまり多くない。
