At least 8 percent of the rotifer’s genes, more than in any other animal, are likely to have been acquired by HGT.
One bacterium can share multiple segments of DNA at once to fellow species members
LGT could raise merry hay with Darwinian attempts to postdict the history of life using Darwin’s natural selection alone.
It disrupts a key thought pattern: How does Darwin explain this? The correct answer is, he doesn’t.
“… they found 49 genes transcribed by the parasite, accounting for 2% of their total transcriptome, which originally belonged to the host. “
“Many microbiologists therefore suspect that nonpathogenic bacteria are acting as a vast pool of ancient resistance genes waiting to be transferred to pathogenic bacteria.”
Where bacteria mutate simply by sharing genes, not by Darwinian struggle, survival of the fittest, etc.
Non-Darwinian evolution: “Cases of ecologically significant HGT in eukaryotes are starting to pile up, …”
“There is no host-parasite relationship between these plants, which is usually when we see this kind of gene movement.”
Another surprising discovery in non-Darwinian evolution.
Just how the slugs make the genetics work remains unclear.
“HGT is an ancient method for bacteria from different lineages to acquire and share useful genetic information they didn’t inherit from their parents.”
In “Antibiotic resistance found in ancient bacteria” (CBC News, Aug 31, 2011), Emily Chung reports, The same genes that make disease-causing bacteria resistant to today’s antibiotics have been found in soil bacteria that have remained frozen since woolly mammoths roamed the Earth. “We’ve shown for the first time that drug resistance is a really old Read More…
