I think when biologists refer to the "pre-genomic" era, they're talking about before the Human genome and other genomes are sequenced. Now that many genomes have been sequenced, they call it the "post-genomic era." I think they're referring to the fact that there's not as much sequencing going on. Since there's so much genomic information available, the next step is to weed through it all, searching for gene function, silencing, and other stuff like that.
