Koepfli and Wayne suspect that zoologists had mistaken African and
Eurasian golden jackals for the same species because of a high degree of similarity in their skull and tooth morphology.
The new study, led by Koepfli and Robert Wayne of the University of California, Los Angeles, was inspired by recent reports suggesting that the
African golden jackal was actually a cryptic subspecies of gray wolf.
Koepfli and Wayne also established collaborations with colleagues, who provided them with samples
from golden jackals in other parts of Africa and Eurasia.
The findings come as a reminder that «even among well - known and widespread species such
as golden jackals, there is the potential to discover hidden biodiversity,» with the help of genomic evidence, Koepfli says.
The researchers say they will continue to study the relationships
among golden jackal and wolf lineages in Africa, Eurasia, and the Middle East.
To expand the DNA evidence in the new study, Wayne retrieved DNA samples of
golden jackals collected two decades ago in Kenya from his laboratory freezers.
[51] Striped hyenas prey

Based on genomic results, the researchers suggest this animal, the

The same story is at play in Europe and Australia, where the researchers examined the relationship between gray wolves and
golden jackals, and dingoes and red foxes, respectively.

Look at the long, slender snout and small body of an African
golden jackal, and you'd be forgiven if you confused it with the golden jackal of Eurasia.
They found that African
golden jackals diverged from coyotes and gray wolves some 1.3 million years ago, compared with 1.9 million years for Eurasian golden jackals, and that the two groups» mitochondrial DNA differs by up to 6.7 %.
