The genus Crocuta (African spotted and Eurasian cave hyenas) includes several closely related extinct and
extant lineages. The relationships among these lineages, however, are contentious. Through the generation of
population-level paleogenomes from late Pleistocene Eurasian cave hyena and genomes from modern African
spotted hyena, we reveal the cross-continental evolutionary relationships between these enigmatic hyena lineages.
We find a deep divergence (~2.5 Ma) between African and Eurasian Crocuta populations, suggesting that ancestral
Crocuta left Africa around the same time as early Homo. Moreover, we find discordance between nuclear and
mitochondrial phylogenies and evidence for bidirectional gene flow between African and Eurasian Crocuta after
the lineages split, which may have complicated prior taxonomic classifications. Last, we find a number of introgressed
loci that attained high frequencies within the recipient lineage, suggesting some level of adaptive advantage

Enzyme immunoassays (EIA) that measure faecal testosterone metabolites (fTM) are useful
tools to monitor gonadal activity. The aim of this study was to validate an “in-house”
epiandrosterone EIA to monitor fTM in spotted ...
