sounds like “deep homology” is showing that many genes were present at the beginning(and never evolved),

That's an unwarranted assumption, IMHO, if it predates the divergence between the plant and animal kingdoms.

How does a gene that build fungal cell walls, learn how to build blood vessels? (completely different structures)

I'm not so sure. Both spheroidal and cylindrical objects require rounded surfaces.

A really great book showing this kind of species transfer/economy of design is “Endless Forms Most Beautiful: The New Science of Evo Devo”, by Sean B. Carroll, 2005. For example the earthworm’s segments, trilobite segments, insect segments and mammalian spine are developmentally related.
