The developmental retardation that causes neoteny is heterochrony--the "alteration and reversal of the sequence of [developmental] stages" in a descendant compared with the developmental sequence of its ancestors (de Beer 1930, 9).
Comments from many participants that these spiders were "cute," "they don't look like spiders," or "they have big eyes" provide anecdotal support for neoteny shaping preference.
The above presented results are consistent with our hypotheses showing that (i) personality traits perceived from faces depend on facial expression, (ii) the evaluations of the 'suggestibility' and 'trustworthiness' traits from individual faces belonging to facial image sets with different expression categories show a consistent (positive or negative) effect regardless of these expressive differences, (iii) perceived 'babyfaceness' (neoteny, immaturity) has an effect on suggestibility in different expressive categories of faces (merry, neutral, "serious"), extending and confirming the earlier findings of Bachmann and Nurmoja (2006).
Many unique characters of Porcelloderes are consequences of neoteny, most importantly the absence of ocelli, the features connected with the strong modification of the whole thorax (posterior lobe of pronotum strongly reduced, no articulating wings present, mesoscutellum not differentiated), and the two-segmented tarsi.
Now there are concepts such as neoteny, which suggests that all humans stop their development at the ape juvenile stage and have developed a bigger brain and a less prognathic face.
* Neoteny is when an adult of a species still retains traits--like big eyes--usually seen only in babies and juveniles.
Although the discussions of neoteny and brain censorship are rather interesting, this book has a number of significant problems from the philosophical, neuroscientific, and scholarly perspectives.
Sean Bonner is a pioneer in the modern internet subculture of social media, being heavily involved in a host of projects including Metblogs and Neoteny Labs.
Evolving systems are poorly adapted to their environments for a host of reasons," and so "literature [may be seen as] a form of play in humans, and adult play exists, not as an adaptation in its own right but as part of selection for juvenile characters in general (neoteny).
In their discussions, the students are invited to offer other potential forces acting on our ancestors, including neoteny. Our brain, even before the last Ice Age, had enough room for ideas like the Internet and the Human Genome Project and the capacity to recognize (and hopefully limit) the impact of our growing population on this planet.
Regarding the importance of lifelong play, in the book and elsewhere you talk about "neoteny," the scientific term for stretching the juvenile period and retention of juvenile characteristics into adulthood.
Simply put, teachers may benefit from employing the ideals of what Bennis and Thomas (2002) call "neoteny." Neoteny is the trait that allows people to adjust to change and circumstances by willingness to learn and in some cases relearn.
