Heteronomous (other)
Heteronomous means 'having different laws' and is used in two contexts: * Heteronomous annulation, an important character in arthropod evolution; * Heteronomous language Autonomy and heteronomy are complementary attributes of a language variety describing its functional relationship with related varieties. The concepts were introduced by William A. Stewart in 1968, and provide a way of distinguishing a ''language ...

Heteronomous Annulation
Heteronomous annulation is a characteristic of some arthropods. It means that segments are differentiated from one another, each having different form so as to serve a different function – for instance, using some limbs for walking and others for feeding. The trait is first observed in the armoured lobopods. It is thought to be the precursor to segmentation in arthropods, and perhaps resulted from the need to produce serially repeated defensive structures (spines). It can be studied using homeotic genes. It is believed to be a trait found in the most recent common ancestor of Panarthropoda. References {{DEFAULTSORT:Heteronomous Annulation Arthropod anatomy ...
