Don't get me wrong. I think the meme notion is fascinating.
Evolution has more concrete "carriers", and DNA is a more concrete form of "meaning".
This makes it easier to track, but in the historical sense differences between species are an approximation of the number of mutations after they branched from a common ancestor.
Memes may originate from a "common thinker", but it would be very difficult to track all of the mutations of that original meme back to that thinker without the meme being written down. So consider pre-written language comparable to the history of mutation before we were able to sequence genomes.
Comparing Catholics to Jews without a record of history is kind of like comparing species without the fossil record. We can tell how many mutations separate them, but not when or if they are of common ancestry.
