Figure 9. Consequences of the Model: Homochirality and Polymers The catalyzing effects of the sites would have crucial consequences by leading to enantioselectivity. Next Experiments Experiments that prove the concept of a complex membrane catalyzing the synthesis of compounds that stabilize its local arrangements are yet to be developed. Need for Lost City-Like Hydrothermal Vents Lipidic vesicle models require specific conditions allowing the vesicles to emerge and persist long enough, including a continuous flow of matter and energy and the possibility for the waste products to be diluted in an open milieu so that the system is not hindered by their increasing concentration [ 9 ].
Synthesis of Lipid Compounds It has already been recognized that vents systems were chemically reactive environments that constituted suitable conditions for sustained prebiotic syntheses [ 28 ]. The Phosphorus Issue The hypothesis that lipidic vesicles were produced on early Earth 4, million years ago at sites such as LCHF makes deep-sea hydrothermal sites the best candidates to be at the origin of evolution and sets new constraints.
Need for a Tectonic Plate Dynamic Regime? Origin of Evolution versus Origin of Life: Consequences Finally, within such a shift of paradigm in the approach of the primordial ancestor, there would be further consequences. Conclusions There is no point in attempting to define life because of the irreducible metaphysical aspect of the concept.
