Never was. Evolution is about how the great VARIETY of life came to be. Abiogenesis is about how LIFE came to be. We don't know about the latter -- not yet; we know a lot about the former.

Never was? That's a crock. It has a long history of being closely associated with evolution. It certainly was in the 60s and 70s when I was in school.
How life came to be is the pink elephant in the room that the evolutionist pretends isn't there. Modern microbiology has clearly established that abiogenesis is impossible, so the evolutionist had to abandon that tenant in order to help maintain some semblance of credibility in evolution.
