Answer:When the mammoth numbers diminished, D'leh's father (the chieftain) left on a quest to find new hunting grounds in order to feed the tribe. Not knowing the true nature of his quest, many tribesmen thought the chieftain left because he was a coward, which was a source of anxiety and guilt for D'leh. Later in the movie, it is learned that D'leh's father was captured by slavers and died as a slave.
