This study suggests that specific genetic changes, including mutations in protein-coding genes and noncoding regions, have contributed to the evolution of hairlessness in multiple mammalian species.
This study identified genetic regions evolving at different rates in hairless mammals, suggesting that specific genomic changes may contribute to the evolution of hairlessness across various species.

April 2018 in “Animal Genetics” This study identified two significant genomic regions potentially involved in hair development and growth in Casertana pigs, highlighting FOXN3 and ARHGEF10 as candidate genes associated with a hairless phenotype.
October 2025 in “International Journal of Advanced Multidisciplinary Research and Studies” This study found that hairless dog breeds have adapted to maintain normal body and core temperatures through structural changes like a thicker epidermis and the role of melanin in thermoregulation, with genetic mechanisms involving the FOXI3 gene governing hairlessness.
