The first time it happened it was physics. The next several billion years it was the purpose.

No, that's not correct. Otherwise grey tin would also have the same purpose. https://en.wikipedia.org/wiki/Tin_pest

This is an allotrope (alternative crystal form) of tin metal that forms spontaneously at very low temperatures and can convert ordinary tin that it touches into the same form at room temperature. (It's not irreversible, as it melts into regular molten tin.). In other words, it's a metal that reproduces. At first due to physics, but after the first time it's purpose, wouldn't you say?
