小狗特性

The least paedomorphic behavior pattern may be that of the basenji , bred in Africa to hunt alongside humans almost on a peer basis; this breed is often described as highly independent, neither needing nor appreciating a great deal of human attention or nurturing, often described as "catlike" in its behavior.

证明狗是从狼快速进化的一个例证是狗是性早熟或幼态持续的。跟大多物种一样，如小狼比起成年狼更偏向群居和比较少的具有支配力；因此，当进行优选时，不管是有意或无意的，最终的结果看来似乎是把这种幼体的特性带入了成年种群中，而非产生一个复杂的独立新行为。对包括人类自身的许多驯养动物皆是如此，人类很多特征与幼倭黑猩猩类似。这种幼态持续选择的结构自然是导致了幼体生理特征的保留。
