Phylogeny vs reticulation in prehistory

Two pure and opposing models exist to give historical account of the structure in modern cultural patterns. A phylogenetic account explores divergence from some shared commonality (the word 'phylogenetic' is from the Greek words for 'tribal origins'). A reticulate account concentrates on a network of interactions (the word 'reticulate' comes via French from the Latin for 'small net'). It follows that neither model may tell all the story. These continuing issues are explored with particular attention to the relations between histories as they are inferred from archaeological and from linguistic patterns.
