The distinctive shape of the Beaker people pottery, is very similar in design to the flower of the Arbutus Tree which the Beaker people used in their daily lives and might well have revered. http://www.treehealthcare.co.uk/strawberry-tree-history/
This research problem is older than the discipline of archaeology itself. Were the `Beaker people´ immigrants or indigenous to prehistoric Britain? Nineteenth century antiquarian barrow-diggers observed that the wide-headed (brachycephalic) skulls of Beaker burials were distinguishable from the narrow (dolichocephalic) skulls within Neolithic long barrows, and attributed these to different populations. Since then, theories of a migrant `Beaker folk´ have been contested by alternative theories which interpret the distinctive Beaker pots and associated material culture as part of a Europe-wide `Beaker package´ or cultural pattern adopted by local communities.
