The new ECEs are far larger than usual — 600,000 to a million nucleotide pairs in a linear DNA stucture. They contain mostly unfamiliar genes, lotsa genes with a variety of functions, and even genes that resemble highly conserved eukaryotic ones. Nineteen different examples have been observed in archaea in California and Colorado. "Borgs" is their suggested nickname, because they appear to have scavenged genes from diverse sources. Geomicrobiologist and team leader Jill Banfield describes them as "a toolbox" of genes that can provide useful capabilities to a species. We know that HGT drives prokaryotic evolution, and large ECEs, "megaplasmids," have been transferred within soil bacteria. Now we see that a Borg is likely another, capacious, gene transfer agent.

Blindness like this is common within science, where specialties are narrow and excommunication is a ready threat. Here, neo-darwinism's ability to produce the software for the origin-of-life and continuing macroevolutionary advances is never questioned. And experimental evidence that would support that capability, in vivo or in silico, is deemed unnecessary. (At least molecular biologist Kirsi Lehto is aware of HGT and viruses.) Titan's dense atmosphere is analysed only for its prebiotic potential — nevermind how it came to be ∼95% nitrogen and ∼5% methane.But the science actually discussed at length is well-referenced and hasn't changed much in the intervening years. So, here is a fine, strictly orthodox, nearly current academic resource.
