What types of genetic markers are researchers analyzing to map divergence times in *Xerus*?
Answer
Mitochondrial DNA and various nuclear genes
Phylogenetic research aimed at determining the evolutionary history, divergence times, and ancestral relationships within the *Xerus* genus and the broader Xerinae group heavily relies on molecular data derived from genetic sequences. The primary markers utilized for this purpose include mitochondrial DNA (mtDNA), which is maternally inherited and evolves relatively quickly, providing good resolution for recent divergences, and various nuclear genes, which offer complementary data from different parts of the genome. Combining these two sources helps create a robust evolutionary map linking genetic splits to geological or climatic events.
