Ontogenesis -

: Humans develop the ability to create meaning before they even have words [1, 19]. It starts with rhythmic movement and "proto-conversations" between infants and caregivers, eventually evolving into structured speech around age 3 or 4 [19, 34].

: The process begins at fertilization [15]. For many species, this includes critical stages like cleavage, gastrulation (the formation of cell layers), and organogenesis [9]. ontogenesis

: Some species experience dramatic shifts during ontogenesis, such as a tadpole’s transformation into a frog [11]. : Humans develop the ability to create meaning

: Ontogenesis doesn't stop at adulthood; it is an ongoing program in the genome that eventually transitions into senescence (aging) [20]. The Human Narrative: Psychology and Culture For many species, this includes critical stages like

In the biological sense, ontogenesis describes the chronological phases an organism undergoes to reach its final form:
