I read that some Y-DNA genetic studies purported to have demonstrated a link between the Guanches, the native inhabitants of the Azores, and Berbers of the neighboring coast of Africa.

While this basal BY36924 appears to have migrated from Morocco, further inspection of the parent clade reveals that this clade has diversified for thousands of years around the Red Sea with no presence in the Maghreb in between.

Fascinatingly, one of the children of CTS10880 migrated to Eritrea and then went on to Kenya perhaps 5000 years ago. This migration may have been along the coast, but as there is no other data a straight line is used to connect the positions.
