Mahr & Csibra (M&C) fail to make the important distinction between why a trait originally evolved, why it was maintained over time, and what its current utility is. Here we point out that episodic memory may have originally evolved as a by-product of a general metarepresentational capacity, and that it may have current functions beyond the communicative domain.
马勒和采斯伯拉（M&C）未能做出重要区分，即一个特征最初是为何进化的，为何其随着时间推移而被保留，以及它目前有何作用。在此，我们指出，情景记忆可能最初是作为一种一般元表征能力的副产品而进化的，而且它可能具有超越交际领域的当前功能。
