Why The Primordial Soup May Be An Alien Concoction
By Tom Chivers


The discovery of 'extremophiles' strengthens the theory that
life was 'delivered' from other planets

In August, Nasa's Curiosity rover, the largest and most
expensive robot ever to be sent to the surface of another
planet, will arrive on Mars. It has several goals, including
studying the climate and geography of the Red Planet, and
providing information for a possible future manned mission. But
Curiosity will also be looking for signs of life and clues as to
where, as well as how, life began - still one of science's
greatest unsolved mysteries.

Ever since Charles Darwin suggested that life may have begun in
a "warm little pond", the idea of the primordial soup has taken
hold in the public and scientific imagination. The hypothesis
states that the chemical building blocks of life mixed together
until a chance event combined them into a replicating being.
That replicator, which would have "lived" around four billion
years ago, is the great-to-the-Nth-power grandparent of every
organism.

The primordial soup explanation has had rivals, but most of them
centre around a similar idea: a replicating process starts on
Earth, and once it is up and running, Darwinian evolution acts
on the offspring of that original ur-organism. In his book The
Blind Watchmaker, Richard Dawkins championed Graham Cairns-
Smith's theory that clay crystals, which preserve information as
they grow from solution, were the first replicators; Nick Lane,
a biochemist at University College London, proposes that they
arose by a hot vent (rather than a warm pond) in the deep ocean.
