The Lusitanian language may in fact have been basal Italo-Celtic, a branch independent from Celtic and Italic, and splitting off early from Proto-Celtic and Proto-Italic populations who spread from Central Europe into western Europe after new Yamnaya migrations into the Danube Valley. Alternatively, a European branch of Indo-European dialects, termed "North-west Indo-European" and associated with the Beaker culture, may have been ancestral to not only Celtic and Italic, but also to Germanic and Balto-Slavic. Prominent modern linguists such as Ellis Evans, believe that Gallaecian-Lusitanian was one same language (not separate languages) of the “P” Celtic variant.
