 Carolina anoles living in central Texas and further north were already adapted to relatively cold temperatures, but those of southern Texas were not.However, after the winter of 2013–2014, the cold tolerance of the southern Texan populations had increased by as much as 1.5 °C (2.7 °F) and their genomic profiles had changed to more closely resemble the more northerly living Carolina anoles.The name for this group of lizards originates from the Carib "anoli".
