Hitting clay with a blast of laser, imitating a blast of a huge meteorite:-
"The researchers zapped clay and a chemical soup with the laser to simulate the energy of a speeding asteroid smashing into the planet. They ended up creating what can be considered crucial pieces of the building blocks of life.-"The findings do not prove that this is how life started on Earth about 4 billion years ago, and some scientists were unimpressed with the results. But the experiment does bolster the long-held theory.-"These findings suggest that the emergence of terrestrial life is not the result of an accident but a direct consequence of the conditions on the primordial Earth and its surroundings," the researchers concluded in the study published Monday in the journal Proceedings of the National Academy of Sciences.-"The laser-zapping produced all four chemical bases needed to make RNA, a simpler relative of DNA, the blueprint of life. From these bases, there are many still-mysterious steps that must happen for life to emerge. (my bold) But this is a potential starting point in that process."-
