Kainogenesis (Noun)
Meaning
Introduction during embryonic development of characters or structure not present in the earlier evolutionary history of the strain or species (such as the addition of the placenta in mammalian evolution).
Classification
Nouns denoting natural processes.
Examples
- Kainogenesis played a crucial role in the evolution of mammals, as the development of the placenta marked a significant shift in their reproductive biology.
- The process of kainogenesis allowed for the introduction of more complex structures and characters during embryonic development, increasing the diversity of life on Earth.
- Studies in embryonic development have shed light on the role of kainogenesis in shaping the characteristics of various species throughout their evolutionary histories.
- In some organisms, kainogenesis occurs through genetic innovations that allow for the formation of new body parts or organs during embryonic development.
- The fossil record suggests that kainogenesis has contributed significantly to the origin of new animal body plans, leading to the wide range of species that exist today.
