Evidence of alien life landed in Wakefield, scientists have claimed.
A balloon which returned from the stratosphere containing organisms believed to have come from space came down close to the city.
And Yorkshire scientists now believe it presents evidence of life arriving on Earth from space, which could change our view of biology and evolution.
The team, from the University of Sheffield, made the discovery after sending a specially-designed balloon 27km above the Earth’s surface during last month’s Perseid meteor shower.
The balloon landed in Wakefield, where the team found organisms that were too large to have originated on Earth.
Professor Milton Wainwright said the results could be revolutionary.
He said: “Most people will assume that these biological particles must have just drifted up to the stratosphere from Earth, but it is generally accepted that a particle of the size found cannot be lifted from Earth to heights of, for example, 27km. The only known exception is by a violent volcanic eruption, none of which occurred within three years of the sampling trip.
“In the absence of a mechanism by which large particles like these can be transported to the stratosphere we can only conclude that the biological entities originated from space. Our conclusion then is that life is continually arriving to Earth from space, life is not restricted to this planet and it almost certainly did not originate here.
“If life does continue to arrive from space then we have to completely change our view of biology and evolution. New textbooks will have to be written.”
