Altermodernism can be defined as that moment when it became possible for us to produce something that made sense starting from an assumed heterochrony, that is, from a vision of human history as constituted of multiple temporalities, disdaining the nostalgia for the avant-garde and indeed for any kind of era - a positive vision of chaos and complexity
The evolutionary origin and elaboration of sociality in the aculeate Hymenoptera: Maternal effects, sib-social effects, and heterochrony.
It was based on developmental sequences, and treated heterochrony as a sequence change.
He suggested an interesting explanation of heterochrony in development, according to which the premature or retarded appearance of organs in ontogeny stands in close relation with the time of their entering upon functional activity.
We find that embryos at the tailbud stage - thought to correspond to a conserved stage - show variations in form due to allometry, heterochrony, and differences in body plan and somite number.
Wise then makes a confusing argument about how the decreasing age of attainment of sexual maturity indicates that lifespan is decreasing (even though it's not) and argues that humans have experienced heterochrony in developmental rates.
(social groups, species), or at different phases of the life cycle (evolution-development), and how other embryological and evolutionary phenomena (heterochrony, neoteny) may influence or impact evolution.
(heterochrony), and allows for extended periods of social learning and language acquisition in juvenile humans.
"altermodernism", which Bourriaud defines as "the moment when it became possible for us to produce something that made sense starting from an assumed heterochrony".
