The Neanderthal lived throughout a widely divergent climate and habitat. These peoples adapted quickly to new environments as they migrated. Some lived in caves, while others built shelters out of branches and animal skins. Still others dug pits and covered them with branches, animal skins and leaves.
Do not free a camel of the burden of his hump; you may be freeing him from being a camel.
G. K. Chesterton
