Another term is "K-selected species"
Ribozymes are biochemically too complex to have ever produced themselves naturalistically. They are an intermediate cellular functioning assembly that cannot survive on its own and they are too restrictive in function to enable metabolism and reproduction at the level of criticality to be considered plausible for life.
Their simplicity relative to RNA and DNA make them an attractive possibility, but they are not strategic enough, robust enough or in any producible using naturalistic processes.
Electromagnetic fields and therefore waves are generated orthogonal to the electric current that generated it.
