Marriage

Traditionally this means the matrimony between a guy and a woman. It is also a vow between the two to support each other.It is generally understood that they will have sex and produce children. However, things has evolved. The following are some "marriages" that is not in the normal sense.

Same sex marriage is a marriage between people of the same sex. This is legal in some countries but is taboo in another. 

Married and not to have child. There are some that agrees not to do it. There are others who are unable to have it. The latter is understandable. 

Child marriage. A marriage between a person of mature age with a child. The two may not have sex till the child is matured. However, this means that the child has not say who he/she is married to.

Human - animal marriage. Practiced by some culture but not necessary legal.

Human - dead marriage. Usually in the form of human - animal marriage. Some culture has this weired practice.

Marriage with a prenuptial agreement. A contract between two person before marriage. I like to call it conditional marriage.

Human and virtual marriage. In Japan there is one guy called Sal9000 who marry a virtual character called Nene Anegasaki, a character in the Nintendo DS game, Love Plus. I like to call it electronic marriage.

Ever heard of married to your work? Work has become more important than family. Although figurative, it should be included in my list.

One to many marriage. It should not be in this list but is worth mentioning. Generally, it is called polygamy. Muslims are allowed to have up to 4 wives. Kings and sultans can have thousands. Some culture practices it while others prohibits it. 

Evolution? Sigh!
