There are those who believe, as did Velikovsky, that things as complex as houseflies can simply pop into existence given the right conditions. The same term applies.
Must be careful with this term since it's not necessarily linked to evolution in many of its manifestations.
It's why we use "Abiogenesis" - life arising from non-life. Whether it's a pop! or many baby steps (more likely) is the same. It is only related to evolution in that successful Abiogenesis gives something for evolution to operate on. The Pasteur/Spontaneous Generation aspect is unrelated to either Abiogenesis or Evolution.
My original question still stands.
