  • Epigenesis is essential for understanding how organisms develop from a single fertilized egg into complex life forms.

Examples

  • Despite differences in individual experiences, each person's neural architecture is shaped through common patterns of brain development, including neuroplasticity, neurogenesis, and epigenesis.

    Academic text (2015)
  • The idea of epigenesis will please those researchers who, like the present reviewer, have seen moderately salt-tolerant algae become strongly halophilic when the salt concentration of the growth medium is increased.

    Academic text (2003)
  • Epigenesis refers to the relationship of environmentally derived neural activity and the influence of genetic code on neural activity.

    Academic text (2015)
  • The study of epigenesis reveals how environmental factors can influence the developmental changes in organisms.

  • Understanding epigenesis helps explain the gradual transformation of a zygote into a fully formed organism.

epigenesis singular

Morphology

epigenesis = genesis (semi-transparent) = epi + genesis

The biological sense ('development from an egg') aligns more clearly with 'genesis' (origin) plus the prefix 'epi-', though specialized; a learner familiar with 'genesis' and common scientific prefixes would likely infer the general idea.

Etymology

Epigenesis comes from the Greek parts epi- 'upon' and genesis 'birth', like in epicenter for epi- and the word genesis for 'origin'. So in biology epigenesis is the idea that a living thing develops step by step after the egg, with new parts forming 'upon' earlier ones.
