 Human Development spans a broad knowledge of human endeavor that has attempted to understand why human beings do the things they do, grow the ways they do, and further what is the potential of human beings.

  There are factors affecting Human Development like heredity, environment and the human reproduction. Each has different roles like heredity is the nature of human development while the environment is used to nurture human being. Under the human reproduction, this the widely factor of human development because it contains the Genetic defects, and the Twins. Twins can be divided into three: identical, fraternal and Siamese.  When we say identical twins this means that there is one sperm that splits into two in order to make two lives. The fraternal twins, this means that there are two sperm cells that live. The last but not the least is the Siamese or what we called conjoined twins, these are the twins who actually have a body conjoining. Some parts of their body are stick together.
