Have you considered exactly how life began on earth? Core evolutionary principles explain the way non-living organic and pre-organic compounds can naturally combine and become selected for growth. But there is an ongoing question regarding the degree to which the seeding of our earth with organic compounds from space contributed to life’s inception here.
Early evolutionary scientists often considered the earth in isolation and presumed that organic compounds primarily evolved on earth from inorganic ones, via chance encounters of these simpler molecules (a process known as abiogenesis). But more recent research has suggested that our universe may more actively provide planets with advanced organic compounds, via supernovae and the gradual formation of complex molecules in interstellar dust clouds. A newly published analysis by the University of Hong Kong supports this changing view.
In the new analysis, researchers examined infrared studies of interstellar dust and found evidence of more complex organic materials than was previously appreciated. The analysis used a novel technique that compared newer dust clouds with older ones, which indicated considerable organic compound formation in these clouds over time. This research suggests significant development of organic compounds in space – or that our universe naturally and widely contains and provides the seeds of life.
