Genetic Analysis Reveals Tsavo Lions' Diet

Recent genomic research on the remains of the infamous Tsavo man-eater lions from 1898 has uncovered insights into their diverse diet, which included humans, giraffes, wildebeests, and other species. The study, published in Current Biology, utilized advanced DNA extraction techniques on hairs found embedded in the lions' damaged teeth, revealing that they preyed on at least six different species. Notably, the presence of wildebeest hair suggests the lions traveled significant distances, raising questions about their hunting range. Lead researcher Alida de Flamingh emphasized the innovative method developed to analyze these ancient hair samples, which could be applied to other historical specimens. The findings not only shed light on the ecological behaviors of these lions but also reflect the impacts of colonization on wildlife in Kenya. This research exemplifies how modern biotechnologies can provide new understanding of historical events and animal behaviors.
