攻击性是发生在以色列Spalax ehrenbergi超级种的地下盲鼹鼠中的多态性特征(NEVO等人,1975年,1986年; NEVO,1991年)。我们发现隔离区的埃及鼹鼠是和平主义者。这支持了我们在Spalax中的侵略性进化理论,该理论预测侵略性在沙漠栖息地应该减少(NEVO等人,1986年),大概是为了尽量减少过热,水和能源消耗。所描述的行为是社会进化的先决条件。我们假设,在北非的Spalax分离株的和平主义行为已适应性地选择生存在恶劣的撒哈拉沙漠生态。
Aggression is a polymorphic trait that occurs in subterranean blind mole rats of the Spalax ehrenbergi superspecies in Israel (NEVO et al., 1975, 1986; NEVO, 1991). We found Egyptian mole rats in the isolates to be pacifistic. This supports our evolutionary theory of aggression in Spalax which predicts that aggression should decrease in the desert habitat (NEVO et al., 1986), presumably to minimize overheating, water and energy expenditure. The described behaviour is a pre-requisite for social evolution. We hypothesize that pacifistic behaviour in Spalax isolates in North Africa has been adaptively selected for survival in the harsh Sahara desert ecology.
