Crania from the Channel Island area of southern California were examined for evidence of traumatic injuries. Well-healed depressed fractures in the outer table of the cranial vault are common in skeletal remains from the northern Channel Islands (18.56% n = 598) but rare in those from the mainland coast (7.5% n = 146). This prevalence of traumatic injuries among the islanders may be a result of intense competition over resources in a geographically circumscribed environment. The frequency of cranial injuries increases significantly between the early and late prehistoric periods on the Channel Islands. This temporal variation appears to reflect changes in patterns of violence associated with population growth and environmental instability.
对来自南加州海峡群岛地区的颅骨进行了检查，以寻找创伤性损伤的证据。颅顶外板愈合良好的凹陷性骨折在北海峡群岛的骨骼遗骸中很常见（18.56%，n = 598），但在大陆海岸的骨骼遗骸中很少见（7.5%，n = 146）。岛民中创伤性损伤的这种普遍性可能是在地理环境受限的情况下对资源激烈竞争的结果。海峡群岛上，史前早期和晚期颅骨损伤的频率显著增加。这种时间上的变化似乎反映了与人口增长和环境不稳定相关的暴力模式的变化。
