More then just lateral gene transfer. An encapsulation of an entire gene ecosystem.

Let's start with a ARN world. Gazillions of independently formed RNA
sequences. Some sequences could associate in a way that they could
reproduce faster and/or efficiently - a biomolecular symbiosis. Some
sequences on the other hand could "predate" others: cliving them and
taking their precious - and progressively more rare - nucleotides.
Some predators could be domesticated by some biomolecular symbionts -
and could be used as a defense against parasite sequences (maybe RNA
virus ancestrals, which insidiously insert themselves in another
sequences, be duplicated and splicing out just to insert again in
another self-reproducing sequence) and/or to "predate" on other
sequences.

Some symbiotic biomolecular association could increase in complexity
giving birth to an authentic genetic system - the gene ecosystem -
which could be encapsulated by protobionts, coacervate or other
vesicular bodies.

Well, surely it is an just-so history now. But maybe it could be
developed in an testable ground someday.
