Morphology

cainogenesis = genesis (semi-transparent) = caino + genesis + caino

Formed from the rare combining form 'caino-' meaning 'new' plus 'genesis' ('origin'); the combining form is technical and unfamiliar to most learners, so the formation is only partially obvious.

Etymology

Cainogenesis comes from Greek parts kaino- meaning 'new' and -genesis meaning 'birth' or 'origin', the same 'gen' in generate. Imagine an embryo growing a brand-new part it did not have before; so cainogenesis means the appearance or origin of new features during development.
