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.
Most African sculpture was historically in wood and other natural materials that have not survived from earlier than, at most, a few centuries ago; older pottery figures can be found from a number of areas. Masks are important elements in the art of many peoples, along with human figures, often highly stylized.frican art takes many forms and is made from many different materials. Jewellry is a popular art form and is used to indicate rank, affiliation with a group, or purely for aesthetics. African jewelry is made from such diverse materials as Tiger's eye stone, haematite, sisal, coconut shell, beads and ebony wood.
