Some people (like myself, my siblings, and some of my nieces and nephews) just have naturally pointed ears. They don't look odd, and are not as pronounced as fake elf ears or spock ears, but would definitely be called pointy by anyone you ask. I guess that is just a variation like any other, like having unusual eye color like violet.
In other cases there is a rare ear deformity called Stahl's ear, which affects the folds of the ears, and in some cases can case them to take on a pointed shape. Although this condition is called "Spock's Ear" or "Vulcan's ear", in many cases Stahl's ears are not pointed. It is common for people to have cosmetic surgery to make their ears look more 'normal' in this case. Stahl's ear may or may not have a hereditary component, but it is thought to be caused by a mutation in the gene's controlling the shape of the folds in the ear. This condition is most commonly found in asians, and is extremely rare in other groups.
In either case, as I said, it's generally a rare thing. I like my pointy ears and think they're quite unique and cute :-)

To fight off air resistance and go faster. If the airplane had a flat nose, (like your palm) the air resistance would affect the nose and make the plane slower, while a pointy nose allows the air resistance to pass by therefore making the plane go faster.
