Expanding on earlier posts, this essay is an iconoclastic perspective of the origin and evolution of the alphabet (the prehistory and history of writing) arrived at through researching the wanderings of my maternal genetic lineage and maternal lineage haplotype ancestors. My indigenous Old European ancestral genetic maternal lineage haplotype, namely U5b (more specifically, U5b1b1-T16192C!], has inhabited Europe for around 40,000 to 50,000 years. The predominant maternal lineage among Old European Paleolithic hunter-gatherers, the U5 mitochondrial DNA haplogroup (known both as Clan Ursula and Clan Europa by genetic scientists, which includes both U5a and U5b haplotypes) is associated with Old Europe's cave art abstract graphical symbols of communication, dating to around 30,000 to 40,000 years ago .
U5b is also genetically associated  with the oldest known verified alphabet, namely the Phoenician alphabet (also called the Proto-Canaanite or Old Canaanite alphabet). Consequently, my ancestral maternal genetic maternal lineage directly links together the first verified alphabet to the abstract cave symbols of Old Europe, making it even more likely that the origin of our alphabet finds its oldest root in Old Europe.
The Phoenician alphabet is thought to be derived from Egyptian hieroglyphics. Like in ancient Phoenicia, the U5b haplotype is also found in ancient dynastic Egypt, where it is linked to both atypical Egyptian hieroglyphics and to the birth of a proto-Sinaitic (Old Canaanite, Old Phoenician) script. In Old Europe, in Ancient Egypt, in Old Phoenicia - where there is abstract alphabetic writing being born and developing, there we as well find U5b (the predominant maternal lineage in Old Europe, but extremely rare in the rest of the world).
The Egyptian goddess Hathor was also known as the Lady of Turquoise, Mistress of Turquoise, Mistress of the West and Mistress of Foreign Lands. Functioning in her aspect as the Eye of Ra, Hathor was additionally known as the lion-lady goddess Sekhmet, one the oldest known deities of ancient Egypt. Hathor may have been a goddess with Old European roots, from lands foreign to Egypt. Hathor's role as the Mistress of Turquoise also conjures up connection to the lovely turquoise blue hues of Old European glaciers [3, 4]. Attributed to the 12th dynastic period, in a Temple to Hathor located in the Sinai mining region, was found a sphinx bearing inscriptions comprised of a mixture of Egyptian hieroglyphs and proto-Sinaitic writing .
Interestingly, also dated to the period spanning the 11th and 12 Egyptian dynasties, the Djehutynakht mummy was of Old European ancestry, carrying the U5b maternal lineage . The local deities of the area in which the Djehutynakht mummy was found were Thoth and his feminine counterpart Seshet, both divine scribes.
These findings (the proto-Sinaitic inscribed sphinx dedicated to the lion-lady goddess from foreign western lands and the U5b Djehutynakht mummy associated with divine scribes) from ancient Egypt link Old European U5b to both the development of proto-Sinaitic writing distinct from Egyptian hieroglyphs, and to the lioness totem of both Egypt (the Sphinx) and Old Europe (the Lion Lady of Hohlenstein Stadel, a cave in Germany).
Taking all of this together, we can propose that U5b women throughout prehistory have been intimately instrumental in the evolution of symbolic graphical communication into true alphabetic writing.
The Lioness of Ursula endures, as does her magic writing.

 My specific ancestral maternal haplotype, namely U5b1b1-T16192C!, is one of the foundational maternal genetic lineages of the Saami of Arctic Fennoscandia. It is also found among the Berbers (Amazighs) of North Africa. The sharing of this U5b1b1-T16192C! genetic link has been dated to around 9000 years ago. Both the Saami and the Berbers carry an extra nucleotide transition (namely, T16144C) that my own specific lineage (namely, U5b1b1-T16192C!) does not carry. My own lineage is a parent branch of the U5b1b1a haplotype shared by the Saami and Berbers.

The first Old European cave symbol (top left) in the video (book list) of Old Paleolithic European Cave Symbols is of the same form as the rune Hagall (of the younger Futhark), known as the "Mother Rune" and "Mother Of All Runes" by many runologists. In runic folklore, Hagall is symbolic of transformation, evolution and Divinely Creative Consciousness. It is also associated with Goddess. Some runologists may refer to this Goddess by the name Runa.
The Old European cave symbol that I identify as the rune Ing (Ingwaz) in the video (my Father Rune) carries many meanings, one of which is of an "empty space." In Kabbalah, it is taught that God contracts part of His Infinite Light (Aur Ein Sof), making a finite "empty space" in which the process of creation unfolds and all creation exists. This process is called Tzimtzum.
