Examples

  • The concept of kainogenesis challenges the idea that all embryonic features are purely ancestral.

  • Some embryologists debate the frequency of kainogenesis in vertebrate development.

  • The study of kainogenesis reveals how species adapt over time.

  • The evolution of the giraffe's long neck is often cited as an example of kainogenesis during embryonic development.

  • The appearance of feathers in bird embryos illustrates the process of kainogenesis in evolutionary biology.

Surface Forms

kainogenesis singular
kainogeneses plural

Morphology

kainogenesis = genesis (opaque) = kaino + genesis + kaino

The form combines the Greek combining form 'kaino-' (new) with 'genesis' (origin), which is structurally clear, but 'kaino-' is an obscure scientific combining form for average learners.

Etymology

Kainogenesis comes from Greek parts kaino- meaning 'new' and -genesis meaning 'origin' or 'creation', like the familiar word genesis. So, kainogenesis refers to the formation in embryos of truly new structures, features that were not present in earlier ancestors.
