Abstract
Domestication leads to the reduction of brain weight, decreases reach from 8.1% in laboratory rats up to 33.6% in domesticated pigs. The question is: Do brain weights increase by feralization? We compared the brain weights of domesticated mammals (cat, dog, pig, goat, ass) with their feral forms. In none of the cases studied, brain weight is increased in wild domestic mammals. So, feral mammals do not return back to the status of their wild species.
摘要
驯化会导致脑重量减轻，减少幅度在实验大鼠中为8.1%，在驯化猪中高达33.6%。问题是：野生化会使脑重量增加吗？我们比较了驯化哺乳动物（猫、狗、猪、山羊、驴）与其野生形态的脑重量。在所研究的所有案例中，野生家养哺乳动物的脑重量都没有增加。所以，野生化的哺乳动物不会恢复到其野生物种的状态。
