Functional | "Adaptive nonshivering thermogenesis (NST) of placental mammals is predominantly mediated by uncoupling protein 1 (UCP1), which resides at high levels in the mitochondrial inner membrane of brown adipose tissue (BAT) (1)." | 10.1126/sciadv.1602878 |
Timing of Loss | "The earliest disruptions of ucp1 function (likely Cretaceous; Fig. 3and table S3) occur in the ancestors of xenarthrans and pangolins,two groups that exhibit marked convergence in many ecological,morphological, and physiological traits and which are generallycharacterized by mediocre temperature-regulating mechanismsand low, labile body temperatures (29–32)" | 10.1126/sciadv.1602878 |
