valonia ventricosa images 1 and 2: valley church bay, antigua, December 2019 – a bubble algae that forms in tropical and subtropical seas
and is sighted as the largest single celled life-form on earth.

sea foam and kelp imagesan clemente, california, 1981 – throughout the intertidal zone, concentrations of dissolved organic matter
such as proteins, lignins, and lipids act as surfactants that create long lasting spumes.

‘natural systems arrange themselves so to reduce their energy content. amphiphilic lipids put into water orientate themselves and group together to form tiny spheres or vesicles. the resulting bilayer boundary separating inside from outside like the phospholipid molecules in cell membranes. this is due to the fact that amphiphilic molecules have a water loving end (hydrophilic) and a water fearing end (hydrophobic). this emergent, self-organising process can work in either direction according to the environmental need, water kept in or out. according to how saturated the liquid is, molecules can add themselves to the structure, growing the vesicle. they are also autocatalitic (acting as templates that trigger the formation of more vesicles) and can in the right conditions even divide’
(robert m. hazen – gen•e•sis –  joseph henry press, 2005)

within the theories relating to the beginnings of life on our planet, micella represent the ‘vesicle first’ principle;
that abiotic conditions created the containers that supported the processes in which genetic life could develop.

for an entity to be distinguished from its surroundings requires a barrier, a membrane
in an aqueous environment a non-aqueous barrier is required
a membrane represents a discrete, potential transition from non-life, to life
life is then recognisable by its partial separation from its surroundings
a membrane is the pre-condition for all metabolism
evolution is the result of materials transferred through semi-permeable membranes

fragment 3.4 – origin

in the watery void
the finest possible lamella
halts the chemical oneness
breaks the singularity
a separation of minute variation
an emergent transition
unfolds its primal bloom
and traces faintly
the first moment
of our existence
