They are similar to micro-organisms found in fossils from the dinosaur age 55 million years ago.

Though critics argued that the rock had probably become contaminated with algae fossils from Earth, Prof Wickramasinghe insisted that they are the remnants of extra-terrestrial life.

He noted that the algae organisms are similar to ones found in Earth fossils and that the rock also has other organisms they have not yet identified.

Are We Aliens On Our Own Planet?

A meteorite that exploded above Canada 11 years ago has provided strong evidence that life’s building blocks came from space.

Fragments of the rock that landed on Tagish Lake, British Columbia, yielded a mix of organic compounds.

They included amino acids and monocarboxylic acids, both essential to the evolution of the first simple life forms on Earth.

Analysis of the chemicals revealed information about their history on the asteroid from which the meteorite came, and lent weight to the theory that organic material originates in gas and dust clouds between the stars.

If the theory is right, the building blocks of life would have been spread throughout our developing solar system.

Lead researcher Dr Chris Herd, of the University of Alberta, said: ‘The mix of pre-biotic molecules, so essential to jump-starting life, depended on what was happening out there in the asteroid belt.

‘The geology of an asteroid has an influence on what molecules actually make it to the surface of the Earth.’

The findings were published in the journal Science.

Experts are confident that the chemicals they analysed were not the result of contamination from the Earth.

Mark Sephton, a geochemist at Imperial College London, who was not involved in the study told The Scientist: ‘It’s real evidence of hydro-synthesis occurring in asteroids and creating compounds that might be biologically useful,’

Meteoriticist Eduardo Iadonisi said this is only the beginning of new discoveries that will number in the dozens in the next few years. “We have some evidence that meteorites will be increasing throughout 2013 and possibly 2014,” said Iadonisi. “It is highly probable that the dozens of meteors soon to impact Earth will also contain some evidence of extra-terrestrial life forms.” Iadonisi could not give an explanation on why more meteorites are impacting Earth, but is confident the trend of discovering alien life forms will continue.

“For all we know, this may be one way the universe is repopulating the Earth with different species,” he concluded.
