I'm not a twin, but I think it's interesting how two offspring canbe produced at the same time. 
Twins are two offspring produced by the same pregnancy.

Kasakela chimpanzee community
The Kasakela chimpanzee community is a habituated community of wild eastern chimpanzees that lives in Gombe National Park near Lake Tanganyika in Tanzania. The community was the subject of Doctor Jane Goodall's pioneering study that began in 1960, and studies have continued ever since. As a result, the community has been instrumental in the study of chimpanzees and has been popularized in several books and documentaries. The community's popularity was enhanced by Goodall's practice of giving names to the chimpanzees she was observing, in contrast to the typical scientific practice of identifying the subjects by number.
Korbinian Aigner
Korbinian Aigner, known as the "Apfelpfarrer" ("apple pastor"), (11 May 1885, in Hohenpolding, district of Erding, Bavaria – 5 October 1966, in Freising, Bavaria) was a Bavarian Catholic priest and pomologist. Korbinian Aigner was born on the substantial family farm at Hohenpolding on 11 May 1885. He was the eldest son and heir to the farm, but renounced his inheritance in favor of his ten younger siblings in order to become a priest. From 1891 Aigner attended elementary school in Hohenpolding. In the autumn of 1896 he moved to the Archiepiscopal Gymnasium (Grammar school) in Freising. In 1904 he was not permitted to graduate however because of his inadequate performance in Greek and Latin studies.
Theogony
The Theogony (, "Theogonía", , i.e. "the genealogy or birth of the gods") is a poem by Hesiod (8th – 7th century BC) describing the origins and genealogies of the Greek gods, composed c. 700 BC. It is written in the Epic dialect of Ancient Greek. Hesiod's "Theogony" is a large-scale synthesis of a vast variety of local Greek traditions concerning the gods, organized as a narrative that tells how they came to be and how they established permanent control over the Cosmos. It is the first Greek mythical cosmogony. The initial state of the universe is chaos, a dark indefinite void considered a divine primordial condition from which everything else appeared.
Twin
Twins are two offspring produced by the same pregnancy. Twins can be either "monozygotic" ("identical"), meaning that they develop from one zygote, which splits and forms two embryos, or "dizygotic" ("fraternal"), meaning that they develop from two different eggs. In fraternal twins, each twin is fertilized by its own sperm cell. In contrast, a fetus that develops alone in the womb is called a "singleton", and the general term for one offspring of a multiple birth is "multiple". Non-related look-alikes whose resemblance parallels that of twins are referred to as doppelgangers. The human twin birth rate in the United States, rose 76% from 1980 through 2009, from 18.9 to 33.3 per 1,000 births.
Pygmy slow loris
The pygmy slow loris ("Nycticebus pygmaeus") is a species of slow loris found east of the Mekong River in Vietnam, Laos, eastern Cambodia, and China. It occurs in a variety of forest habitats, including tropical dry forests, semi-evergreen, and evergreen forests. The animal is nocturnal and arboreal, crawling along branches using slow movements in search of prey. Unlike other primates, it does not leap. It lives together in small groups usually with one or two offspring. An adult can grow to around long and has a very short tail. It weighs about . Its diet consists of fruits, insects, small fauna, tree sap, and floral nectar.
Auckland Zoo
Auckland Zoo is a zoological garden in Auckland, New Zealand, situated next to Western Springs park not far from Auckland's central business district. It is run by the Auckland Council with the Auckland Zoological Society as a supporting organisation. Auckland Zoo opened in 1922 experiencing early difficulties mainly due to animal health issues. By 1930 a sizeable collection of animals had been assembled and a zoological society formed. The zoo consolidated during the Second World War and was at that time under the leadership of Lt. Col. Sawer. After the war the collection was expanded, and in the 1950s chimpanzees were acquired to provide tea parties for the public's entertainment, but this practice ceased in 1964.

Oh yeah. I have known a lot of twins in my life and I find it a pretty cool phenomenon.

For fraternal twins each twin is fertalized by its own sperm cell. 
In fraternal twins, each twin is fertilized by its own sperm cell.

Twin study
Twin studies reveal the importance of environmental and genetic influences for traits, phenotypes, and disorders. Twin research is considered a key tool in behavioral genetics and in content fields, from biology to psychology. Twin studies are part of the broader methodology used in behavior genetics, which uses all data that are genetically informative – siblings studies, adoption studies, pedigree, etc. These studies have been used to track traits ranging from personal behavior to the presentation of severe mental illnesses such as schizophrenia. Twins are a valuable source for observation because they allow the study of environmental influence and varying genetic makeup: "identical" or monozygotic (MZ) twins share nearly 100% of their genes, which means that most differences between the twins (such as height, susceptibility to boredom, intelligence, depression, etc.)
Sperm
Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) "sperma" (meaning "seed"). In the types of sexual reproduction known as anisogamy and its subtype oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. A uniflagellar sperm cell that is motile is referred to as a spermatozoon, whereas a non-motile sperm cell is referred to as a spermatium. Sperm cells cannot divide and have a limited life span, but after fusion with egg cells during fertilization, a new organism begins developing, starting as a totipotent zygote.
Irving Gottesman
Irving Isadore Gottesman (December 29, 1930 – June 29, 2016) was an American professor of psychology who devoted most of his career to the study of the genetics of schizophrenia. He wrote 17 books and more than 290 other publications, mostly on schizophrenia and behavioral genetics, and created the first academic program on behavioral genetics in the United States. He won awards such as the Hofheimer Prize for Research, the highest award from the American Psychiatric Association for psychiatric research. Lastly, Gottesman was a professor in the psychology department at the University of Minnesota, where he received his Ph.D.  A native of Ohio, Gottesman studied psychology for his undergraduate and graduate degrees, became a faculty member at various universities, and spent most of his career at the University of Virginia and the University of Minnesota.
Chimera (genetics)
A genetic chimerism or chimera (also spelled chimaera) is a single organism composed of cells with distinct genotypes. In animals, this means an individual derived from different zygotes, which can include possessing both female and male sex organs, blood cells of two blood types, or subtle variations in form. Animal chimeras are produced by the merger of multiple fertilized eggs. In plant chimeras, however, the distinct types of tissue may originate from the same zygote, and the difference is often due to mutation during ordinary cell division. Normally, genetic chimerism is not visible on casual inspection; however, it has been detected in the course of proving parentage.
Robotic sperm
Robotic Sperm (also called spermbots) are biohybrid microrobots consisting of sperm cells and artificial microstructures. Currently there are two types of spermbots. The first type, the tubular spermbot, consists of a single sperm cell that is captured inside a microtube. Single bull sperm cells enter these microtubes and become trapped inside. The tail of the sperm is the driving force for the microtube. The second type, the helical spermbot, is a small helix structure which captures and transports single immotile sperm cells. In this case, a rotating magnetic field drives the helix in a screw-like motion.
Beginning of human personhood
The beginning of human personhood is the moment when a human is first recognized as a person. There are differences of opinion as to the precise time when human personhood begins and the nature of that status. The issue arises in a number of fields including science, religion, philosophy, and law, and is most acute in debates relating to abortion, stem cell research, reproductive rights, and fetal rights. Traditionally, the concept of personhood has entailed the concept of soul, a metaphysical concept referring to a non-corporeal or extra-corporeal dimension of human being. However, in modernity, the concepts of subjectivity and intersubjectivity, personhood, mind, and self have come to encompass a number of aspects of human being previously considered to be characteristics of the soul.

Are those the type of twins that don't look alike?
