What gave birth to life on Earth? This study says Meteorites brought DNA to Earth! Check this shocking origin of life study.
Everyone has always wondered once in their lifetime, ‘how did humans come to Earth?’ What is origin of life? Scientists are working closely to know what exactly gave birth to life on Earth. Answers and theories have brought endless possibilities. Though, this intriguing study brings another interesting angle about the origin of life on Earth. It says that DNA, the essential building block of life, came from Space! This new study, which was released in the magazine Nature Communications, says that Meteorites could have been responsible for delivering the basis of life’s genetic code, DNA, on Earth.
The study claimed that researchers found nucleobases in meteorites, this is the substance that makes the structure of DNA. The researchers studied the sample of three meteorites, one of which had crashed to Earth way back in 1950 in the American town of Murray in Kentucky. Another meteorite landed in Australia’s Victoria State in 1969 and the third one hit the Canadian province of British Columbia in 2000.
Meteorites are behind the origin of LIFE on Earth?
The close analyses of these meteorites, which are known to be rich in organic materials, demonstrated that both types of nucleobase, the same compounds that form the genetic information in DNA, could have originally had an origin outside the Earth. There are chances that after the formation of nucleobases in outer space, these meteorites worked as the delivery agents of DNA molecules to Earth, which later became the building block of all genetic coding for life.
“During the formation of Earth, many common elements and compounds with low boiling points, known as volatiles, would not have been present. We believe that many of these, such as water, were delivered afterward by meteorites, which may have also delivered organic molecules,” Dr. Helena Bates, who researches asteroids at the Museum said in a statement.
