Brown Adipose Tissue. Everyone is familiar with white adipose or fat tissue, which provides insulation and, by storing triglyceride, serves as an energy depot. Many mammals also have brown adipose tissue, which also stores triglyceride, but has the unique ability to generate heat.
What is the Earliest Art of Northern Africa? The oldest prehistoric art from North Africa is the early Stone Age quartzite figurine from Morocco known as the Venus of Tan-Tan. It has been carbon-dated to the period 200,000-500,000 BCE, and probably was created by advanced Acheulian peoples of north-western Africa on the main southerly route into Southern Europe.
Luckily, two archaeological sites, Samun Dukiya and Taruga, were found containing Nok art that had remained unmoved. Radiocarbon and thermo-luminescence tests narrowed the sculpturesâ age down to between 2,000 and 2,500 years ago, making them some of the oldest in West Africa.he refinement of this culture is attested to by the image of a Nok dignitary at the Minneapolis Institute of Arts. The dignitary is portrayed wearing a crooked baton ([3] , [4]). The dignitary is also portrayed sitting with flared nostrils, and an open mouth suggesting performance.
