I wanted to make sure I had the use of the word “meme” correct, so I did a quick dictionary search. The second definition has an interesting point.

Memes can be considered the unit of cultural evolution. Ideas
can evolve in a way analogous to biological evolution. Some
ideas survive better than others; ideas can mutate through,
for example, misunderstandings; and two ideas can recombine to
produce a new idea involving elements of each parent idea.

(…)

Use of the term connotes acceptance of the idea that in humans
(and presumably other tool- and language-using sophonts)
cultural evolution by selection of adaptive ideas has become
more important than biological evolution by selection of
hereditary traits. Hackers find this idea congenial for
tolerably obvious reasons.
