I'm sorry , that isn't what is said either.<quoted text>
Indeed the evolutionary paradigm of a single cell evolving has long changed. Models based on HGT/LGT now conclude that there were multiple 'primitive cells' that swapped DNA.
IOW, evolutionary researchers do not know but need to tie all life together somehow.
What the research brings home to me is that genomic similarity is not 'proof' of common ancestry. Following evolutionary reasoning then multiple form of primitive 'life' that arose independently were so genetically similar that they were able to interact genomically with each other, LGT.
It appears by evolutionists own reasoning life can arise independently and be genomically similar.
The evolutionary path from a common descent connection between all known living organisms, has already been established.
These papers do not refute that , what it says is we should look for hidden biota and new phyla of life. To understand what that means , look at this page.
There are about 30 different phyla of animals, and indeed some life seems alien to us already but...
Have we missed some things that existed long age, and/or does anything else exist that is unknown or alien to what we have discovered. Like this.
That's what it talking about.
