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.
Sculpture is the most common example of Egyptian art that we have today, and specimens exist that date to the Predynastic period. Most of these are pottery and figurines, but these already show expressionistic qualities in the painting of the pottery, and many clay figures even represent local gods. In the Old Kingdom ( roughly 2700-2100 B.C.), sculpture mainly represented the royal family members. They were portrayed in a very solid, symmetrical, blocklike fashion.
