Humans may have evolved with plant genes, study claims
This isn't the weirdest thing. We're half-virus too: http://www.newscientist.com/article/mg20...human.html

Quote:Humans may have evolved with the genes of plants, fungi and micro-organisms, according to a consensus-challenging Cambridge University study.

The study into the literal roots of mankind builds on, and to some extent confirms, the findings of a 2001 investigation into whether or not humans could have acquired DNA from plants.

It was heavily criticized at the time for being too weedy.

It is now accepted in some quarters that up to one percent of our genome could have originated in plants by way of horizontal genetic transfer, or HGT, a complex process in which particular bacteria transfer information about DNA.

The research suggests that humans, like certain other species, carried the DNA of organisms which lived in their surrounding environment rather than obtaining it through the much more linear process of breeding and descent.

In a statement on the University of Cambridge website, Dr. Alistair Crisp, lead author of the project undertaken by the Department of Chemical Engineering and Biotechnology, said: “This is the first study to show how widely horizontal gene transfer occurs in animals, including humans, giving rise to tens or hundreds of active 'foreign' genes.”

“Surprisingly, far from being a rare occurrence, it appears that this has contributed to the evolution of many, perhaps all, animals and that the process is ongoing. We may need to re-evaluate how we think about evolution.”

In an article for the Genome Biology journal published Friday, the authors of the report further explained: “HGT occurs at low, but appreciable, levels across all the animal species we examined; it has occurred over time and is still occurring; it mainly originates from bacteria and protists; and the genes concerned frequently code for enzyme activities.”

“Interestingly, overall levels of HGT do not appear to be conspicuously different in vertebrates and invertebrates. This is surprising given the difference in complexity between the groups, but may be explained by the observed older HGT in primates, suggesting that the vertebrate HGT may have occurred at an earlier stage of vertebrate evolution.”

Most customers I have to deal with are 100% vegetables.


Not in haunts of marble chill,
Temples drear where ancients trod,—
Nay, in oaks on woody hill
Lives and moves the German God.

Most of them do still, with weed.

RE: Humans may have evolved with plant genes, study claims
If I recall correctly, Darwin mused on such possibilities, though he was unable to know the mechanisms involved, and pointed at how farmers were loathe to have their prize breeding animals ever mate with a low quality partner, for fear of something being passed over to reduce the value of subsequent offspring. Until this present sort of thing was discovered, too many in the education system, if not science itself, were too ready to heap scorn on this sort of idea. Naturally, there are lessons here for humans too, who should be wary of who their spouses have slept with prior to themselves.... ;)

"And now if a whole nation fell into that? In such a case, I answer, infallibly they will return out of it. For life is no cunningly-devised deception or self deception, it is a great truth that thou art alive, that thou hast desires, necessities: neither can these subsist and satisfy themselves on delusions, but on fact. To fact, depend on it, we shall come back: to such fact, blessed or cursed, as we have wisdom for."

Well shit, telegony is back. Added another reason to the million reasons I'm never having kids. Tongue

Looks like theres a study showing the possibility a child can gain DNA from a previous pregnancy. I'd steer well away from somebody with a nog sprog anyway in any sort of relationship 1488.

Guess the Orthodox Church in Russia's use of telegony years ago to promote virginity and fidelity paid off.
