Thank you, thank you, THANK YOU for being so clear about the fact that genes don't mutate with any sort of goal in mind! Evolution is so often presented as some kind of deliberate act, a hero story of overcoming adversity through willful adaptation. If the genetic variation doesn't exist, there's nothing to be selected for or against. Without that understanding, the vital importance of genetic diversity in a population is lost.

Obviously the Angel of Supply Chains overordered massively on recurrent laryngeal nerves and the restocking fee was too high, so the Angels of Necks were forced to use the materials to cover up the discrepancy from the Angels of Internal Audits.

Ah yes, the Recurrent Mammalian Laryngeal Nerve. Present in every mammal species discovered to date and proof of one of two things: 1) Evolution is true, or 2) The deity responsible for our design is a comically incompetent engineer.
