@oristarA,
Some of the most recent findings about abiogenesis revolve around "Tubules" found in 4.2 By 'banded iron" Formations (Not Mesabi). Ince iron predates the task of "over concentrated Oxygen), Its early "life-like" propwrties are lately of interest.
"Fossil" iron tubules have three proprties that make it the latest "flavor" for abiogenesis
1.The tubeules show photic direction for an entire formational boundary
2The tubules xhibit spiral structure that could serve as a biotic "cast" for severl spiral feqtures in molecules within more complex organim
3The tubules, by exhibiting brnching, seem to indicate growth and metabolim
4All the iwotopic ratios of Carbon within the iron tubule are C12>>C13.
Look like life ay not be s Unique as weve been trying to make it. Abiogenesis may have happened quickly .Banded irons occur between 4.2 to 2.7 BILLION years back (come next saturday) .
Organic Evolution begins after life first appears. Abiogenesis seems to hve occured severl ways and maybe margulis was correct that very early life may have been variable, commensal and sequentially integrated. . Go back to your circular "Common ancestry" cladogram (It was the wheel with which ) you started this thread ).
They are attempting to discover Lambda values (geologic ages for the participants). Most of the Lambda values will be studied from the non-coding sections of the genomes, since these segments have upper limits to their population variability.
Recent research seems to be clustering away from concentrations on "pre biotic chemical evolution" to an analogy more about a planetray junkyard in which "junk parts"(pre biotic blobs,, layers, and tubules) fester in a water and ammonia soup base ,and in which pieces of the junk just happens to fit together"
In that , I see my pet statement of "dont forget panspermia " as something that needs more careful analysis before always its dismissed.
