Neoteny in humans is further indicated by the limbs and body posture, with the limbs proportionately short compared to torso length; [2] longer leg than arm length; [6] the structure of the foot; [1] and the upright stance. [7] [8] Humans also retain a plasticity of behavior that is generally found among animals only in the young. The emphasis ...
Neoteny in humans is the slowing or delaying of body development, compared to non-human primates, resulting in features such as a large head, a flat face, and relatively short arms. These neotenic changes may have been brought about by sexual selection in human evolution .

The video begins with the subject's genitals in a non-aroused flaccid state (0:00). As arousal progresses(0:30), the subject's penis becomes erect , the scrotum tightens and the testicles elevate.

Steven J. Gould discussed the presentation of neoteny with "terminal additions" in humans. [8] Neoteny is defined as the delayed or slowed development in humans when compared with their non-human primate counterparts. The "terminal additions" were extensions or reductions in the rate and scope of stages of development and growth.
X-ray photos show the sounds [i, u, a, ɑ]. The IPA defines a vowel as a sound which occurs at a syllable center. [69] Below is a chart depicting the vowels of the IPA. The IPA maps the vowels according to the position of the tongue.
For example, you may pronounce cot and caught, do and dew, or marry and merry the same. This often happens because of dialect variation (see our articles English phonology and International Phonetic Alphabet chart for English dialects). If this is the case, you will pronounce those symbols the same for other words as well. [1]
referring to human adults - this is misusing the word "neoteny" to mean "youthfulness", and apart from being unreferenced speculation hence does not belong in this discussion.
