Origins of the Tedbears

Tedbears are a species (plural) of teddy bear-esque lifeforms that exist on Earth, alongside its humans, flora, fauna and vehicles.

Origins
Although the Tedbears have lived on Earth for countless millennia, the exact whereabouts of their native home is currently unknown. The most credible theories hypothesize that Teds have extraterrestrial origins, and were introduced to Earth through a spacecraft crash many thousands of years ago.

Spread of Tedkind
Teds take many shapes and forms. Although the standard bipedal Tedbear is most common, it has been observed that literally any animal (barring the Human,) vehicle or inanimate object may possess Ted features -- usually a Tedsnout, beady ted eyes and ted ears. Until the 1940s, the cause of these "Mutations" remained a mystery. It was not until the Operation Crossroads atomic bomb tests in 1946 that T.E.Ds, the atmospheric particles which are responsible for Mutations, were discovered.

T.E.D. is an acronym for Theodoric Entity Droplets. These microscopic molecules, not present before the Teds' introduction to Earth, are woven into the planet's atmosphere, and are the reason why many of its native species mutate into Ted hybrids. However, the vast majority of Earthian life possess some degree of immunity from Ted mutations, resulting in a relatively peaceful coexistence between unmodified forms of the planet's native inhabitants and those who react to T.E.D. It should be noted that Humans are completely immune to these particles.

In 1960, it was revealed by Theo Razzledazzle Bloohopper, the Grand Scribebear of the Ted Archives2 at the time, that the Humans' T.E.D. particle theory was indeed correct. This event was unique in that it was the first time that top-secret Tedbear archival data was willingly shared with Man. It was made known that the T.E.D. particles were accidentally released from highly pressurized glass jars containing its concentrated form. The jars were broken by mistake during the event in which Tedbears first made landfall on Earth.
