Greek DNA

Ever since the days of Homer, Greeks have long idealized their Mycenaean “ancestors” in epic poems and classic tragedies that glorify the exploits of Odysseus, King Agamemnon, and other heroes who went in and out of favor with the Greek gods. Although these Mycenaeans were fictitious, scholars have debated whether today’s Greeks descend from the actual Mycenaeans, who created a famous civilization that dominated mainland Greece and the Aegean Sea from about 1600 B.C.E. to 1200 B.C.E., or whether the ancient Mycenaeans simply vanished from the region.

Now, ancient DNA suggests that living Greeks are indeed the descendants of Mycenaeans, with only a small proportion of DNA from later migrations to Greece. And the Mycenaeans themselves were closely related to the earlier Minoans, the study reveals, another great civilization that flourished on the island of Crete from 2600 B.C.E. to 1400 B.C.E. (named for the mythical King Minos).
When the researchers compared the DNA of modern Greeks to that of ancient Mycenaeans, they found a lot of genetic overlap. Modern Greeks share similar proportions of DNA from the same ancestral sources as Mycenaeans, although they have inherited a little less DNA from ancient Anatolian farmers and a bit more DNA from later migrations to Greece.

The continuity between the Mycenaeans and living people is “particularly striking given that the Aegean has been a crossroads of civilizations for thousands of years,” says co-author George Stamatoyannopoulos of the University of Washington in Seattle. This suggests that the major components of the Greeks’ ancestry were already in place in the Bronze Age, after the migration of the earliest farmers from Anatolia set the template for the genetic makeup of Greeks and, in fact, most Europeans. “The spread of farming populations was the decisive moment when the major elements of the Greek population were already provided,” says archaeologist Colin Renfrew of the University of Cambridge in the United Kingdom, who was not involved in the work.


Doesn't seem to mesh well with traditional theories about the invasions of the Dorians or the "Sea Peoples" and the end of the Mycenaean civilization:
Wikipedia wrote:Mycenaean Greece perished with the collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the so-called Greek Dark Ages, a recordless transitional period leading to Archaic Greece where significant shifts occurred from palace-centralized to de-centralized forms of socio-economic organization (including the extensive use of iron). Various theories have been proposed for the end of this civilization, among them the Dorian invasion or activities connected to the "Sea Peoples". Additional theories such as natural disasters and climatic changes have been also suggested.
