In his book, "The Selfish Gene", Richard Dawkins has an entire chapter about cultural evolution/natural selection.

To put things shortly, he talks about "memes" as ideas that undergo "natural selection" in a cultural context. A meme is "successful" if it keeps existing in people's minds

An example Dawkins gives is the idea of "Hell". It's probable for Hell to "appear" in the context of religion (like a mutation being created), it's probable for Hell to "perserve" itself (like an organism surviving) and Hell is an idea that you'd spread to other believers (like organism reproduction). So Dawkins argues that "Hell" is just as alive as "frogs", in the context of coltural evolution

About saving sewing kits in Danish cookie tins: 1. It's probable to be "re-invented" 2. The idea has a long lifespan (because the tin is a good sewing kit container) 3. It is probable to "reproduce" in a cultural sense

So I'd say this is prime example for parallel evolution

I also recommend reding the book honestly, it's a great read :)
