Било је речи на другим темама о овој грани хаплогрупе R1b. Она би могла да буде добар кандидат за Хетите и Лувијце, тј. грана коју су Прото-Хетити донели на Балкан из источноевропских степа и потом у Малу Азију, током другог миленијума п.н.е. Изумрли хетитски, лувијски и палајски језик, који припадају анадолској породици индоевропских језика, су најособенији у односу на друге ИЕ језике, што говори о томе да су се одвојили раније, док је прото-ИЕ језик још увек био у својој архаичној фази; PF7562 је исто тако грана која се најраније издвојила из М269. Послужићу се цитатима из књиге Дејвида Ентонија, америчког археолога, "The horse, the wheel and the language-how Bronze Age riders from Eurasian steppes shaped the modern world":
"Hittite, Luwian, and Palaic had evolved already by 1900 BCE. This is a critical piece of information in any attempt to date Proto-Indo-European. All three were descended from the same root language, Proto-Anatolian. The linguist Craig Melchert described Luwian and Hittite of the empire period, ca. 1400 BCE, as sisters about as different as twentieth-century Welsh and Irish. Welsh and Irish probably share a common origin of about two thousand years ago. If Luwian and Hittite separated from
Proto-Anatolian two thousand years before 1400 BCE, then Proto-Anatolian should be placed at about 3400 BCE. What about its ancestor? When did the root of the Anatolian branch separate from the rest of Proto-Indo-European?"
"Linguists do not use the term proto- in a consistent way, so I should be clear about what I mean by Proto-Anatolian. Proto-Anatolian is the language that was immediately ancestral to the three known daughter languages in the Anatolian branch. Proto-Anatolian can be described fairly accurately on the basis of the shared traits of Hittite, Luwian, and Palaic. But Proto-Anatolian occupies just the later portion of an undocumented period of linguistic change that must have occurred between it and Proto-Indo- European. The hypothetical language stage in between can be called Pre-Anatolian. Proto-Anatolian is a fairly concrete linguistic entity closely related to its known daughters. But Pre-Anatolian represents an evolutionary period. Pre-Anatolian is a phase defined by Proto-Anatolian at one end and Proto-Indo-European at the other. How can we determine when Pre-Anatolian separated from Proto-Indo-European? The ultimate age of the Anatolian branch is based partly on objective
external evidence (dated documents at Kanesh), partly on presumed rates o flanguage change over time, and partly on internal evidence within the Anatolian languages. The Anatolian languages are quite different phonologically and grammatically from all the other known Indo-European daughter languages. They are so peculiar that many specialists think they
do not really belong with the other daughters. Many of the peculiar features of Anatolian look like archaisms, characteristics
thought to have existed in an extremely early stage of Proto-Indo-European."
"For some Indo-Europeanists these traits suggest that the Anatolian branch did not develop from Proto-Indo-European at all but rather evolved from an older Pre-Proto-Indo-European ancestor. This ancestral language was called Indo-Hittite by William Sturtevant. According to the Indo-Hittite hypothesis, Anatolian is an Indo-European language only in the broadest sense, as it did not develop from Proto-Indo-European. But it did preserve, uniquely, features of an earlier language community from which they both evolved. I cannot solve the debate over the categorization of Anatolian here, although it is obviously true that Proto-Indo-European must have evolved from an earlier language community, and we can use Indo-Hittite to refer to that hypothetical earlier stage. The Proto-Indo-European language community was a chain of dialects with both geographic
and chronological differences. The Anatolian branch seems to have separated from an archaic chronological stage in the evolution of Proto-Indo-European, and it probably separated from a different geographic dialect as well, but I will call it archaic Proto-Indo-European rather than Indo-Hittite."
"A substantial period of time is needed for the Pre-Anatolian phase. Craig Melchert and Alexander Lehrman agreed that a separation date of about 4000 BCE between Pre-Anatolian and the archaic Proto-Indo-European language community seems reasonable. The millennium or so around 4000 BCE, say 4500 to 3500 BCE, constitutes the latest window within which Pre-Anatolian is likely to have separated."
Балкански PF7562 би највероватније били потомци "пре-анадолског слоја" на Балкану, о коме говори Ентони у свом раду, дакле они који за разлику од Хетита и Лувијаца никада нису закорачили на тло Мале Азије.
