Researchers Extract 50,000-Year-Old Antelope DNA in Sub-Saharan Africa, Setting a Regional Record

Summary
A 50,000-year-old mountain reedbuck tooth from South Africa's Boomplaas Cave yielded the oldest DNA yet recovered in sub-Saharan Africa, far beyond the region's previous animal record of 9,300 years.
More than 300 animal teeth spanning the past 110,000 years were tested, and a small number preserved usable DNA, showing Late Pleistocene remains can survive Africa's heat longer than many researchers assumed.
The record-setting sample is not definitive: lead author Deon de Jager said it was contaminated with human DNA and is much older than the next-oldest sequences, from extinct long-horned buffalo dated to 21,000 and 12,000 years ago.
Even so, the team says the fragments are enough to trace evolutionary lineages, and a separate 42,000-year-old wildebeest genome from Ethiopia suggests ancient DNA may be recoverable across more African sites.
The finding could extend genetic study of African animal and human evolution back 40,000 to 50,000 years, though researchers say DNA from much older hominins such as Homo naledi is still very unlikely to survive.
Will ancient proteins, not DNA, be the key to finally mapping the complete human evolutionary tree from Africa?
What older molecular secrets from Africa's human cradle are now waiting to be unlocked by these new techniques?
Does finding only female *Homo naledi* remains reveal a complex ancient ritual or a simple twist of fossil fate?
50,000-Year-Old DNA Recovered in Sub-Saharan Africa: Breakthroughs, Challenges, and the Future of Ancient Genomics
Overview
This report highlights the remarkable progress in recovering ancient DNA from Sub-Saharan Africa, a region where hot and humid conditions have long made DNA preservation difficult. Despite these challenges, scientists are now identifying specific environments—such as deep caves and high-elevation sites—that offer stable, low temperatures ideal for long-term genetic survival. The exact limits of DNA preservation in Africa remain unclear, but ongoing research suggests that many promising locations have yet to be discovered. These breakthroughs open new possibilities for understanding Africa’s ancient ecosystems and human history, reshaping scientific assumptions about DNA survival in challenging climates.
