TPFECF Contributes to Groundbreaking New Aardwolf Genetic Study

Twin Pine Farm & Exotics Conservation Foundation is proud to announce that the TPFECF Aardwolf Project contributed to a newly published scientific study examining the genetics and chromosome structure of the aardwolf (Proteles cristatus), one of the world’s least-studied carnivores.

The study, published in the Journal of Heredity by researchers at Texas A&M University and the University of Florence, represents the first detailed chromosome-level cytogenetic analysis ever completed for the aardwolf. Researchers compared aardwolf chromosomes to those of spotted hyenas and domestic cats in order to better understand how the species evolved and how it differs genetically from other hyenas.

TPFECF and its Aardwolf Project were formally acknowledged in the publication for providing the skin biopsy sample from a female aardwolf that made the study possible. The authors wrote:

“The authors are grateful to Ms. Sheri Sublett from Twin Pine Farm & Exotics Conservation Foundation (TPFECF) and their Aardwolf Project for providing a skin biopsy sample from the female aardwolf used in this study.”

For TPFECF, this recognition reflects our continued commitment to science-based management, collaborative zoological partnerships, and advancing knowledge of rare and underrepresented species.

So what does the study actually mean?

Researchers confirmed that the aardwolf has 40 chromosomes, similar to the other hyena species, but also identified several unique chromosome features that distinguish the aardwolf from its closest relatives. Most notably, the study found that one chromosome in the aardwolf has a structure not seen in spotted hyenas, providing researchers with a genetic marker that can help identify and better understand the species.

The study also demonstrated that the aardwolf shares a remarkable amount of chromosome similarity with both spotted hyenas and domestic cats. By comparing chromosome segments between these species, researchers were able to trace evolutionary relationships and identify areas of the genome that have remained stable over millions of years.

These findings are important because they provide a foundation for building the first high-quality chromosome-level genome assembly for the aardwolf in the future. That will help researchers better understand:

• Genetic differences between eastern and southern populations of aardwolves  

• Evolutionary history within the hyena family  

• Traits unique to the aardwolf, including its highly specialized insectivorous lifestyle  

• Long-term conservation planning and responsible population management  

For TPFECF, this work supports our broader goal of developing a sustainable, collaborative conservation program for the species through the TPFECF Aardwolf Project and the ZAA Aardwolf Animal Management Program.
