The continental shelf is a gently sloping feature found at the edge of a continental landmass going seaward from the coast. Rivers that empty into the sea can produce currents that are strong enough to erode the material that builds the shelf. When this occurs channels or submarine canyons are formed. These canyons are deep and dark as no light can penetrate these regions. The canyons often lead out to sea towards the edge of the shelf.
I do not think it's more common in a certain group. It's one of the most common genetic birth defects. It's estimated that 1 in 700 babies are born with down syndrome (this is about 6,000). There are over 400,000 people in the US with Down syndrome.
The answer is no, fibrocartilage cannot provide articular surface as smooth as the original hyaline cartilage.
This is because these two cartilages are different in composition (structure) and thus provide slightly different function.
Fibrocartilage is stiff and contains many collagen fibers type I and II, while hyaline cartilage is a soft cartilage that contains collage fibers type I. Fibrocartilage contains only few chondrocytes in lacunae, while hyaline cartilage has large number of them. As a result, fibrocartilage provide a restricted mobility, while hyaline cartilage enables smooth movements.
