No sense in dismissing possibilities because you don't like them. That
applies to biology and electronics. Nature invents "improbable
mechanisms" which have a "scientific basis" when shown to exist.

The ideas of jumping genes, reverse transcription, and epignetic
switching were all mocked, known to be impossible, by the rigid
neo-Darwinists. I think there's all sorts of cool stuff waiting for
old farts to die so they can be considered and discovered.
Mitochondria are sadly neglected.

Evolution by random mutation and natural selection is for losers.
Losers are also known as lunch.

Most people, including most engineers, are instantly hostile to
unauthorized ideas. That's fine with me... it leaves me more stuff to
invent and sell.
