Scientists found evidence of poisoned arrows from 60,000 years ago in South Africa. This is the oldest confirmed use of arrow poison ever identified.

Scientists have discovered that people living in southern Africa 60,000 years ago used poisonous plants to make their hunting more effective. They analyzed old quartz arrowheads and found residues from a highly toxic plant called gifbol (Boophone disticha). This plant is still used by traditional hunters today. The discovery shows that our ancestors were not only skilled at making bows and arrows but also knew how to use nature's chemistry to increase their hunting success.

The researchers, led by Professor Sven Isaksson from Stockholm University, analyzed 60,000-year-old quartz arrowheads recovered from Umhlatuzana Rock Shelter in KwaZulu-Natal. They found two specific alkaloids, buphanidrine and epibuphanisine, which are only found in Boophone disticha.

This discovery is significant because it provides direct evidence of the use of poisoned arrows 60,000 years ago. Until now, researchers have relied on indirect clues to suggest that early humans used poison in hunting.

The same chemical signatures were detected on 250-year-old arrowheads preserved in Swedish museum collections. This suggests that this knowledge was passed down across countless generations.

Why It Matters

This discovery shows how advanced and clever our ancestors were. It also highlights the importance of understanding plants and their properties, which is still relevant today. As students in India, you can learn from this example and appreciate the ingenuity of our ancestors.
