Total bullshite.
Nope
The commonly accepted model of evolution is based on duplication, rearrangement, and mutation of genes with the idea of common descent, IAW with lineage-specific genes.

Translation:
Evolution absolutely could occur (and almost certainly has) independent of orphan genes.

Orphan genes are the result of duplication and mutation. They are unique to species because they exist in entirely different states, or in the case of duplication not at all, than in the ancestor species.

They are so different that we cannot link them to any genes in other species, but that doesnt mean they just appeared out of thin air.
