I would say they have meaning in a different sense - not as a message but their origin as proof. They are fundamentally proof of the "tautological mechanism" of evolution. It isn't a matter of life but that things which can survive over time and are produced over time will have a higher number existing at once than ones which perish and are not produced. This holds regardless of the how and why.
Native copper ore got largely picked up and used by humans rendering such deposits "extinct" from early civilizations and lead to the practice of mining after the low hanging fruit was used up.
Dekhn is correct in ascribing this to complex information systems though, it is the storage, copying, transmission and expression of DNA that gives viruses their opportunity. All of these mechanisms can be hijacked.
