The muscles of the foot, along with a tough, sinewy tissue known as the plantar fascia, provide secondary support to the foot. The foot has internal muscles that originate and insert in the foot and external muscles that begin in the lower leg and attach in various places on the bones of the foot.
A haplogroup is a genetic population group of people who share a common ancestor on the patrilineal or matrilineal line. Haplogroups are assigned letters of the alphabet, and refinements consist of additional number and letter combinations.NPs are locations on the DNA where one nucleotide has mutated or switched to a different nucleotide. Because a haplogroup consists of similar haplotypes, it is possible to predict a haplogroup from the haplotype.
Main article: Haplogroup J (mtDNA). Haplogroup T is thought to have originated in the Middle East about 30,000 years ago. It is found throughout Europe, the northern half of Africa through the Near East to Central Asia and Siberia, with pockets in India and North-West China (Xinjiang). is the oldest of all Y-DNA haplogroups. It originated in sub-Saharan Africa over 140,000 years ago, and possibly as much as 340,000 years ago if we include haplogroup A00. Modern populations with the highest percentages of haplogroup A are the Khoisan (such as the Bushmen) and the southern Sudanese.
