Ancient Wooden Structure Unearthed on Zambia-Tanzania Border

Researchers have discovered what is believed to be the world's oldest known wooden structure on the border of Zambia and Tanzania. The arrangement of logs, dating back at least 476,000 years, was likely made by Homo heidelbergensis and may have served as a walkway or platform. The logs show signs of being cut, chopped, and scraped with stone tools. The discovery provides insight into early human ingenuity and the use of wood in shaping the environment. The site is expected to yield more ancient wooden objects and efforts are underway to have it recognized as a UNESCO world heritage site.
