Fraternal twins can look very similar or completely different. Sometimes look almost identical, sometimes not at all.
A multiple birth occurs when more than one fetus is carried to term in a single pregnancy. The preceding pregnancy is called a multiple pregnancy. Different names for multiple births are used, depending on the number of offspring. Common multiples are two and three, known as twins and triplets, respectively. These and other multiple births occur to varying degrees in most animal species, although the term is most applicable to placental species.
Multiple birth siblings are either monozygotic or polyzygotic. The former result from a single fertilized egg or zygote splitting into two or more embryos, each carrying the same genetic material (genes). Siblings created from one egg are commonly called identical. Since identical multiples share the same genetic material, they are always the same sex. Polyzygotic (or fraternal) multiples instead result from multiple ova being ripened and released in the same menstrual cycle by a woman's ovaries, which are then fertilized to grow into multiples no more genetically alike than ordinary full siblings, sharing 50% of their genetic material. Multiples called "dizygotic" represent multiples from two eggs specifically. For example, a set of triplets may be composed of identical twins from one egg and a third non-identical sibling from a second egg.
The evil twin is an antagonist found in many different fictional genres. They are physical copies of protagonists, but with radically inverted moralities. In filmed entertainment, they can have obvious physical differences with the protagonist—such as facial hair (often a goatee), eyepatches, scars or distinctive clothing—that make it easy for the audience to visually identify the two characters. Sometimes, however, the physical differences between the characters will be minimized, so as to confuse the audience. Both roles are almost always played by either the same actor or the actor's actual twin (if the actor has one).
Though there may be moral disparity between actual biological twins, the term is more often a misnomer. In many cases, the two look-alikes are not actually twins, but rather physical duplicates produced by other phenomena (e.g. alternate universes). In others, the so-called "evil" twin is more precisely a dual opposite to their "good" counterpart, possessing at least some commonality with the value system of the protagonist.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
