阅读有两句话求解释

来自陈虎平阅读书里的，在63页，例16里。

有下面一段话

Young children do imitate their parents in all societies, but they imitate many other people as well: older sibings, nonfamily adults and children, and characters they see on televison.

Rowe has pointed out that it would not make evolutionary sense for children to learn only from their parents; it would mean, for example, that children might fail to pick up useful innovations unless the innovator happened to be their parent.

标红的两句话理解起来比较费劲，感觉前后有矛盾，我知道是我理解有误，请大家指教。

我的理解是：

第一句话：儿童不会仅仅从他们的父母那里得到进化性的感觉。也就是说儿童可以从其他人那里学习到这种sense。

第二句话：儿童可能会获取创新失败，除非那个创新者是他们的父母。也就是说，儿童的学习者不是他们的父母，学习创新就可能会失败。

那么前后不是矛盾了吗？我到底是哪里理解错了？
