Aardwolves and cats share surprising chromosome similarities, study finds
Texas A&M UniversityIn the first detailed chromosome map of the aardwolf, Texas A&M University researchers have discovered that, despite millions of years of separate evolution, the chromosomes of aardwolves, other hyenas and even domestic cats have remained remarkably similar.
The aardwolf, a termite‑eating mammal native to Africa, is the least‑studied member of the hyena family. Until now, the only chromosome information on the aardwolf was its chromosome count — 40 — which was discovered in the 1960s.
The study, published in the Journal of Heredity, was led by Dr. Terje Raudsepp, a professor in the Texas A&M College of Veterinary Medicine and Biomedical Sciences’ (VMBS) Department of Veterinary Integrative Biosciences, in collaboration with Twin Pine Conservation Institute (TPCI).
The new study provides the first detailed look at the species’ whole chromosomes, or karyotype, and contributes to broader efforts to build chromosome‑level references for mammals. So far, only about 1,200 of roughly 6,000 mammal species have detailed chromosome maps.
