一个同义反复的进化时间？
而对具体个体的存在进行选择解释就是同义反复的。
There would be a tautology only in the case that the selection explanation is applied to the existence of special individuals.
这并不是同义反复的恒真命题，为什么不能有只能通过非科学方法发现的事物呢，又甚或有根本发现不了的事物？
That is no tautology. Why can't there be things only discoverable by non-scientific means, or not discoverable at all?
