Genetics link Angola's 'ghost elephants' to populations hundreds of miles away

Phys · · 1086 words · By Chelcey Adami
Wildlife Biology Conservation Genomics Interdisciplinary Collaboration

Stanford University researchers used DNA analysis from fecal samples to study a population of nocturnal 'ghost elephants' in eastern Angola. The genomic data suggests these elephants are most closely related to populations in Namibia, though a direct link to a historically large elephant named Henry remains unproven.
