The astonishing thing here is that not only is it far more complex than imaginable a short while ago, the chemicals are actually very similar, and in some cases exactly the same as used in living systems today. Allamandola said the experiment shows that the molecules needed to produce cell membranes, and thus life, are everywhere. Life is not so simple Others were more cautious about the implications of the findings. But Davies and others point out that the cell membrane was likely the last step in the formation of life. And forming a potential cell wall, or any other inanimate part of a cell, is far simpler than gathering the information, contained in DNA, that powers cells and creates life.
Bricks are easy to make, because they are simple.
The same goes for life. The cell membrane is about the simplest feature of the lot. Like the scientists involved in the study, Genge points out that this does not mean that life exists in space. But these complex molecules might serve as sort of a ready mix of ingredients for life when delivered to a planet with the right conditions.
