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.

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.

Yup, that's because they have two different combinations of DNA

Yup'ik clothing
Yup'ik clothing (Yup'ik "aturaq" "aturak" "aturat" , "aklu", "akluq", "un’u" ; also, "piluguk" in Unaliq-Pastuliq dialect, "aklu", "cangssagar", "un’u" in Nunivak dialect) refers to the traditional Eskimo-style clothing worn by the Yupik people of southwestern Alaska. Also known as Cup'ik clothing for the Chevak Cup'ik-speaking people of Chevak and Cup'ig clothing for the Nunivak Cup'ig-speaking people of Nunivak Island. The traditional clothing system developed and used by the Eskimo peoples is the most effective cold weather clothing developed to date. Yup'ik women made clothes and footwear from animal skins (especially hide and fur of marine and land mammals for fur clothing, sometimes birds, also fish), sewn together using needles made from animal bones, walrus ivory, and bird bones such as front part of a crane's foot and threads made from other animal products, such as sinew.
Yup'ik
The Yup'ik or Yupiaq (sg & pl) and Yupiit or Yupiat (pl), also Central Alaskan Yup'ik, Central Yup'ik, Alaskan Yup'ik (own name "Yup'ik" "Yupiik" "Yupiit" ), are an Eskimo people of western and southwestern Alaska ranging from southern Norton Sound southwards along the coast of the Bering Sea on the Yukon-Kuskokwim Delta (including living on Nelson and Nunivak Islands) and along the northern coast of Bristol Bay as far east as Nushagak Bay and the northern Alaska Peninsula at Naknek River and Egegik Bay. They are also known as Cup'ik by the Chevak Cup'ik dialect-speaking Eskimos of Chevak and Cup'ig for the Nunivak Cup'ig dialect-speaking Eskimo of Nunivak Island.
Yup'ik language
Central Alaskan Yup'ik or just Yup'ik (also called Yupik, Central Yupik, or indigenously Yugtun) is one of the languages of the Yupik family, in turn a member of the Eskimo–Aleut language group, spoken in western and southwestern Alaska. Both in ethnic population and in number of speakers, Central Alaskan Yup'ik is the largest of the languages spoken by Alaska Natives. As of 2010 it was also the second largest aboriginal language in the United States in terms of numbers of speakers. Yup'ik should not be confused with the related language Central Siberian Yupik spoken in Chukotka and St. Lawrence Island.
Yup'ik cuisine
Yup'ik cuisine ("Yupiit neqait" in Yup'ik language, literally "Yup'iks' foods" or "Yup'iks' fishes") refers to the Eskimo style traditional subsistence food and cuisine of the Yup'ik people from the western and southwestern Alaska. Also known as Cup'ik cuisine for the Chevak Cup'ik dialect speaking Eskimos of Chevak and Cup'ig cuisine for the Nunivak Cup'ig dialect speaking Eskimos of Nunivak Island. This cuisine is traditionally based on meat from fish, birds, sea and land mammals, and normally contains high levels of protein. Subsistence foods are generally considered by many to be nutritionally superior superfoods.
Yup'ik dancing
Yup'ik dancing (or dance) or Yuraq, also Yuraqing (Yup'ik "yuraq" "yurak" "yurat" ) is a traditional Eskimo style dancing form usually performed to songs in Yup'ik, with dances choreographed for specific songs which the Yup'ik people of southwestern Alaska. Also known as Cup'ik dance for the Chevak Cup'ik dialect speaking Eskimos of Chevak and Cup'ig dance for the Nunivak Cup'ig dialect speaking Eskimos of Nunivak Island. Yup'ik dancing is set up in a very specific and cultural format. Typically, the men are in the front, kneeling and the women stand in the back. The drummers are in the very back of the dance group.
Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen, via the Fab's variable region. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can "tag" a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival).
Genetics
Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.
