Twin

Twins are two offspring produced by the same pregnancy. Twins can either be monozygotic ("identical"), meaning that they can develop from just one zygote that will then split and form two embryos, or dizygotic ("fraternal"), meaning that they can develop from two different eggs; each are fertilized by separate sperm cells.

In contrast, a fetus which develops alone in the womb is called a singleton, and the general term for one offspring of a multiple birth is multiple.

Statistics

The twin birth rate in the United States rose 76% from 1980 through 2009, from 18.9 to 33.3 per 1,000 births. The Yoruba have the highest rate of twinning in the world, at 45–50 twin sets (or 90–100 twins) per 1,000 live births, possibly because of high consumption of a specific type of yam containing a natural phytoestrogen which may stimulate the ovaries to release an egg from each side.

In Central Africa there are 18–30 twin sets (or 36–60 twins) per 1,000 live births. In Latin America, South Asia, and Southeast Asia, the lowest rates are found; only 6 to 9 twin sets per 1,000 live births. North America and Europe have intermediate rates of 9 to 16 twin sets per 1,000 live births.

Twin (windowing system)

Twin (acronym for "Textmode WINdow") is a windowing environment with mouse support, window manager, terminal emulator and networked clients, all inside a text mode display.

Twin supports a variety of displays:

Twin is tested on Linux (x86, PowerPC, DEC Alpha, SPARC) and on FreeBSD; porting to SunOS is in progress.

Uses

The terminal emulator Eterm has an interface layer named Escreen for interoperating with the terminal multiplexers GNU Screen or Twin. This allows Eterm to support multiple sub-shell sessions within a single window. This feature works similarly to the "tabbed" sessions offered by terminal emulators such as Konsole or GNOME Terminal. However, being an interface to existing software, Escreen has the advantage of providing additional capabilities like multiple regions per display, detach/reattach capability, seamless remote session support, firewall support, and more.

Twins in mythology

Twins appear in the mythologies of many cultures around the world. In some they are seen as ominous and in others they are seen as auspicious. Twins in mythology are often cast as two halves of the same whole, sharing a bond deeper than that of ordinary siblings, or otherwise shown as fierce rivals. Twins can represents some "other" aspect of the Self, a doppelgänger or a shadow. Often the twin is the "evil twin" , or one may be human and one semi-divine. The twin may be a brother, or a soul-mate, such as the "civilized" Gilgamesh and the "wild" Enkidu.

Many cultures have mythic or folkloric explanations for how twins are conceived. In Greek mythology, some twins were conceived when a woman slept with both a mortal and a god on the same day. One of her offspring thereafter had godlike qualities, and the other was an ordinary mortal, such as Heracles and his twin brother Iphicles. In several Native American cultures women avoided eating twin fruits like double almonds and bananas because it was thought to increase the likelihood of twins. In other cultures, twins were attributed to superior virility of the father.
