Even those who have worked with the species for years say that we will likely never know whether it was an act of aggression or overexuberant play—or even if, as some have suggested , it was premeditated.

甚至是跟这个物种在一起工作了数十年的工作人员们也说，我们可能永远也不会知道这次事件到底是源于一次侵略攻击行为还仅仅是为了闹着玩过了头--或者即使是像某些人所说的那样，这是一次有计划的谋杀事件。

密码表应用体系中，从DNA分子到m RNA分子到t RNA，再到核糖体到肽链，没有一步使用了排列数计算方法，从而造成DNA分子信息传递时步步失真，最后变成了肽链具体位置上的氨基酸分子，这里的每一步信息传递都是对密码表的错误运用。
