Dr Arnaud-Haond added that there was a theory that even asexual reproduction could not continue indefinitely because tiny "copy errors" accumulated in the genes over time.
I have never heard of such a scientific theory. Maybe the relevant scientists or anyone else could enlighten me on it. Maybe Dr Arnaud-Haond was taking aim at creationist theories when saying this?
Isn't this idea called evolution? Mutations occur in clonal species as well, and these would have to be copy errors, right?

However, the study - which sampled seagrass across 3,500km of the Mediterranean Sea - found seagrasses with identical genomes spreading across large areas and large distances, challenging that theory.
So, I guess the researcher is challenging creationists?
Actually, I find it incredibly interesting that seagrass in one spot, and sea grass in another spot, separated by thousands of km and thousands of years would be genetically identical. Mutations should have made
some difference over this long of time, shouldn't it?
