Researchers have reported that the Amondawa tribe, who were first discovered in the depths of the Amazon rainforest in 1986, have no notion of time as an abstract concept.
Chris Sinha, Professor of Psychology of Language at the University of Portsmouth, confirms that the tribe have no words in their language for 'time', 'month' or 'year'.
Sinha also states that "female Amondawas often go out to collect berries and plants for meals and don't return for days on end.
They seem to have no sense of urgency when they are gathering food and it is not unusual for search parties to have to be sent out to find them.
But they don't seem to be have been disorientated when they are located and don't appear to be have been upset by the experience".
Its also alleged that the women in the tribe also tend to come back with many more food stuffs than they originally went out to collect.
