Biologist Wolfgang Schleidt presents a convincing scenario which Homo sapient or even the earlier Homo erectus gathered in small nomadic groups in Northern Europe and joined the wolves in the following of migratory reindeer.

Wolves taught us to be more skilful hunters in tracking prey, and they added the power of their deadly fangs and claws to early humans' sharpened sticks and stone clubs.
