This grey nurse shark (Carcharias taurus) and the smaller fish surrounding it are animals.

Animals (from the Latin animale and animalis, meaning "living", and anima, meaning "vital breath", or "soul") are those organisms classified into the kingdom Animalia. Together they make up a wide segment of lifebiologists estimate their species to number many millions—and include an incredibly diverse array of both familiar and strange creatures, ranging from hawks to humans and from sea slugs to spiders. Nonetheless, they all share certain characteristics: all animals are multicellular eukaryotes, ingest their food, and move by their own power at some point in their life cycle. Animals are essential consumers in many ecosystems and many are also important in human societies and economies.

Definition

Like "plant", the term "animal" has gone through several definitions along history. Animals—moving life—were distinguished from plants—unmoving life—by Aristotle in his works on metaphysics and logic. Aristotle continued to influence classification of plants all the way to Carl Linnaeus, who divided all life into the two kingdoms Animalia and Vegetabilia. Some animals such as coral were considered plants because they appeared sessile and similar to plants' branches. Additionally, many protists were formerly classified as "microscopic animals" because, like animals, they actively moved and ate other organisms.[more...]

The modern Taliban (طالبان; from the Farsi plural of Arabic طالب, meaning "student") movement, or the Taliban Islamic Movement of Afghanistan (TIMA), took control of Afghanistan in 1994, imposing a strict Salafist rule, as or more conservative than the Wahhabi movement of Saudi Arabia. Both featured a "Department for Promoting Virtue and Preventing Vice." They argued they were creating a stable Islamic state that the leaders of the jihad against the Soviets could not create. [1]

At the present time, the modern Taliban forms a substantial part of the insurgency in the Afghanistan War (2001-), as well as an active insurgency in Pakistan. The Taliban historically had a strong presence in the Federally Administered Tribal Areas near the border between Pakistan and Afghanistan. After continuing fighting in areas along the Afghan border, Pakistan negotiated with Taliban fighters. [2] Fighting continued, and, on May 7, 2009, Prime Minister Yousef Raza Gilani of Pakistan formally revoked a peace agreement with the Taliban, accusing the Taliban of repeated violations. Taliban forces had fought to within 60 miles of Islamabad, the capital of Pakistan. [3] [more...]
