Although the global genetic structure of lions, including the relationship between the extant and extinct lineages, has been explored in previous studies, these inferences were based on mitochondrial DNA (mtDNA) data (5-8), or a limited number of mitochondrial and autosomal markers (9, 10).Here, we expand on these prior findings with whole-genome resequencing data from a set of modern .

They grunt when they move from one area to another.
