The acquisition of domestic animals was an epoch-making event in cultural evolution. When did man arrive at such a cultural standard that he was able to live in fairly peaceful coexistence with wild animals, and start the process of taming which finally produced genuine tame or domestic animals? It appears that for hundreds of thousands of years man lived as food-gatherer, hunter or fisherman without domestic animals of any kind. At least the presence of domestic animals was not shown in any of the many palaeolithic settlements known today, nor from the palaeolithic cave-drawings. Only from the Mesolithic is there the first certain, but weak evidence of any domestic animal and the finds show that the dog was among the first animals to be domesticated and attached to human settlements.

Among the oldest and best-known skeletal material of the domestic dog are the Danish finds from the Maglemosian settlements from the bogs at Mullerup, Svaerdborg, Holmegaard, Lundby and Aamosen near Halleby river, all in Zealand. Very few dog bones were found, although tens of thousands of bones have been excavated from these settlements. The dog bones, like those of other animals used for food, were very fragmentary, and several showed marks where they had been cut.

The Maglemosian settlements date from the Boreal period, pollen zones V and VI, i.e. they go back to the time when Denmark was covered with vast pine forests and was part of the European continent.
