How will the study of the Kennewick Man help scientists solve the mystery of how early man arrived in the New World

Explanation:The mysterious Kennewick Man, who died 9,000 years ago in the Columbia River Valley, was a seal hunter who rambled far and wide with a projectile point lodged in his hip, five broken ribs that never healed properly, two small dents in his skull and a bum shoulder from the repetitive stress of throwing spears.

He came from somewhere far away, far up the Pacific Northwest coast, possibly Alaska or the Aleutian Islands. He might even have come to North America all the way from Asia.
