Study: Humble clays may have been birthplace of life on Earth

Clay may have been the birthplace of life on Earth despite being a seemingly infertile and inhospitable blend of minerals, some U.S. scientists say.

Life, or at least the complex biochemicals that make life possible, could have formed within a kind of clay known as a hydrogel, containing a mass of microscopic spaces capable of soaking up liquids like a sponge, Cornell University biological engineers report in the journal Scientific Reports.

"We propose that in early geological history clay hydrogel provided a confinement function for biomolecules and biochemical reactions," biological and environmental engineering Professor Dan Luo said.

In seawater, clay forms a hydrogel, and over billions of years chemicals confined in those spaces could have carried out the complex reactions that formed proteins, DNA and eventually all the machinery that make a living cell work, the Cornell researchers suggest.

The noted that geological history shows clay first appeared on Earth -- as silicates leached from rocks -- just at the time biomolecules began to form into protocells and eventually membrane-enclosed cells.

The geological events matched nicely with biological events, they said.

EXO LIFE
Life, but not as we know it
Nottingham, UK (SPX) Nov 05, 2013
A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep normal replication processes and reproduce by the back door, researchers at The University of Nottingham have found. The study, published in the journal Nature, centres on Haloferax volcanii - part of a family of single-celled organisms called archaea that until recently were thought ... read more
