What is neotenous?

1 : retention of some larval or immature characters in adulthood. 2 : attainment of sexual maturity during the larval stage.

Are humans neotenous?

Neoteny in humans is the retention of juvenile features well into adulthood. Humans also retain a plasticity of behavior that is generally found among animals only in the young. The emphasis on learned, rather than inherited, behavior requires the human brain to remain receptive much longer.

Are dogs neotenous?

Neoteny is seen in domesticated animals such as dogs and mice. Often, juvenile behaviors are selected for in order to more easily domesticate a species; aggressiveness in certain species comes with adulthood when there is a need to compete for resources.

Are cats neotenous?

One important difference between domesticated cats and all other domesticated species is that domesticated cats are not neotenous (literally, baby-like). Since human adults innately respond to those characteristics in human babies, it makes sense that domesticated animals would share some of those characteristics.

What is neotenic development?

Neoteny (/niˈɒtəni/), also called juvenilization, is the delaying or slowing of the physiological (or somatic) development of an organism, typically an animal.

What is permanent neoteny?
