Cross-species summary: Absence of the tail. Also called anury.

Molecular basis: Xia et al. (2024) "present evidence that an individual insertion of an Alu element in the genome of the hominoid ancestor may have contributed to tail-loss evolution. [The authors] demonstrate that this Alu element—inserted into an intron of the TBXT gene pairs with a neighbouring ancestral Alu element encoded in the reverse genomic orientation and leads to a hominoid-specific alternative splicing event."
