What happened
At Igbo-Ukwu, at present on the northern limit of the rain-forest zone, there were old land surfaces with spreads of charcoal dated to the eleventh and seventh millennia BC. If the charcoal resulted from natural bush-fires it may indicate a savanna-type vegetation surviving to this era at latitude 6°N, consistent with the northward advance of forest after 10,000 BC.
