"In terms of evolution, the oldest physiological role of AhR is in development. AhR is presumed to have evolved from invertebrates where it served a ligand-independent role in normal development processes. The AhR homolog in Drosophila, spineless (ss) is necessary for development of the distal segments of the antenna and leg. Ss dimerizes with tango (tgo), which is the homolog to the mammalian Arnt, to initiate gene transcription. Evolution of the receptor in vertebrates resulted in t… " - Bap ahr
