Evolution obviously doesn't need abiogenesis, but it definitely needs (is dependent upon) PE.
No, it needs neither because, hypothetically, if the evidence was for always things evolving at the same rate, the theory of evolution would work just as well as an explanation.
The EVIDENCE needs PE to explain it; evolution theory doesn't need that evidence for PE and the evolution process doesn't need PE to work.
..claiming irreducible complexity has been debunked
All claims of irreducible complexity in living things have been shown to be nothing of the sort and not one example of such claimed irreducible complexity has stood up to any scrutiny;
https://en.wikipedia.org/wiki/Irreducible_complexity
"....
Researchers have proposed potentially viable evolutionary pathways for allegedly irreducibly complex systems such as blood clotting, the immune system[89] and the flagellum[90][91] - the three examples Behe proposed. John H. McDonald even showed his example of a mousetrap to be reducible.[50]
If irreducible complexity is an insurmountable obstacle to evolution, it should not be possible to conceive of such pathways.[92]..."
