Neotenic is an adjective that refers to the retention of juvenile or infantile characteristics in adulthood. Derived from the Latin term "neotenia," meaning "delayed development," it is used to describe an organism that exhibits physical or behavioral traits typically associated with immaturity or early stages of development, even after reaching reproductive maturity. This phenomenon is particularly prominent in some animal species.
In the context of biology, neoteny can result from genetic or environmental factors that influence the rate of development or maturation. It can manifest as the retention of child-like features such as a larger head, big eyes, or a more delicate body structure in adult individuals. It can also impact behavioral traits, causing adults to retain behaviors commonly observed in young animals, such as curiosity, playfulness, or submissive behaviors.
Neotenic features can serve various purposes, including the enhancement of reproductive success, adaptation to specific ecological niches, or domestication by humans. For instance, certain dog breeds exhibit neotenic traits, such as floppy ears and shorter snouts, as a result of selective breeding.
The term "neotenic" can also be metaphorically used to describe human characteristics or behaviors that are reminiscent of childhood or immaturity. In psychology, it may refer to individuals who retain child-like qualities, such as a sense of wonder, creativity, or a youthful appearance well into adulthood.
Overall, neotenic describes the phenomenon of delayed maturation or the retention of infantile features and behaviors in adult organisms.
