Somali art is the artistic culture of the Somali people, both historic and contemporary. These include artistic traditions in pottery, music, architecture, wood carving and other genres. Somali art is characterized by its aniconism, partly as a result of the vestigial influence of the pre-Islamic mythology of the Somalis coupled with their ubiquitous Muslim beliefs. However, there have been cases in the past of artistic depictions representing living creatures, such as certain ancient rock paintings in northern Somalia, the golden birds on the Mogadishan canopies, and the plant decorations on religious tombs in southern Somalia. More typically, intricate patterns and geometric designs, bold colors and monumental architecture were the norm.
What animals are depicted on the Mogadishan canopies?
birds

Biodiversity provides critical support for drug discovery and the availability of medicinal resources. A significant proportion of drugs are derived, directly or indirectly, from biological sources: at least 50% of the pharmaceutical compounds on the US market are derived from plants, animals, and micro-organisms, while about 80% of the world population depends on medicines from nature (used in either modern or traditional medical practice) for primary healthcare. Only a tiny fraction of wild species has been investigated for medical potential. Biodiversity has been critical to advances throughout the field of bionics. Evidence from market analysis and biodiversity science indicates that the decline in output from the pharmaceutical sector since the mid-1980s can be attributed to a move away from natural product exploration ("bioprospecting") in favor of genomics and synthetic chemistry, indeed claims about the value of undiscovered pharmaceuticals may not provide enough incentive for companies in free markets to search for them because of the high cost of development; meanwhile, natural products have a long history of supporting significant economic and health innovation. Marine ecosystems are particularly important, although inappropriate bioprospecting can increase biodiversity loss, as well as violating the laws of the communities and states from which the resources are taken.
What percentage of worldwide drugs are derived from nature?
about 80%

In diffuse-porous woods the pores are evenly sized so that the water conducting capability is scattered throughout the growth ring instead of being collected in a band or row. Examples of this kind of wood are alder, basswood,[citation needed] birch, buckeye, maple, willow,and the Populus species such as aspen, cottonwood and poplar. Some species, such as walnut and cherry, are on the border between the two classes, forming an intermediate group.[citation needed]
Is maple wood diffuse-porous or ring-porous?
diffuse-porous
