Document New discovery proves 'selfish gene' exists

New discovery proves 'selfish gene' exists

A new discovery by a scientist from The University of Western Ontario provides conclusive evidence which supports decades-old evolutionary doctrines long accepted as fact.

Since renowned British biologist Richard Dawkins ("The God Delusion") introduced the concept of the 'selfish gene' in 1976, scientists the world over have hailed the theory as a natural extension to the work of Charles Darwin.

In studying genomes, the word 'selfish' does not refer to the human-describing adjective of self-centered behavior but rather to the blind tendency of genes wanting to continue their existence into the next generation. Ironically, this 'selfish' tendency can appear anything but selfish when the gene does move ahead for selfless and even self-sacrificing reasons.

For instance, in the honey bee colony, a complex social breeding system described as a 'super-organism,' the female worker bees are sterile. The adult queen bee, selected and developed by the worker bees, is left to mate with the male drones.

Because the 'selfish' gene controlling worker sterility has never been isolated by scientists, the understanding of how reproductive altruism can evolve has been entirely theoretical – until now.

Working with Peter Oxley of the University of Sydney in Australia, Western biology professor Graham Thompson has, for the first time-ever, isolated a region on the honey bee genome that houses this 'selfish' gene in female workers bees.

This means that the 'selfish' gene does exist, not just in theory but in reality. "We don't know exactly which gene it is, but we're getting close."

I agree that the article is too short and doesn't go into a lot of things they should.

At the very least they should provide a quotable statement along the lines of this showing that self-sacrifice and altruism can be a genetic trait that can be passed down.

Provides another argument against the "without God there is no reason to be altruistic" point.

Should this gene not be called the 'unselfish gene', since it apparently prevents the sterile worker females from 'selfishly' reproducing competing offspring? It seems to me that this would make more sense, because it appears this gene is an 'exception', and the other genes are the 'selfish' ones. I'm probably missing something here, but the article is rather short on detail.

Like others, I do hope Richard posts a better explanatory comment on this article.

Arent selfish genes simply genetic elements that are replicated either alone or together with the genome but dont provide any advantage to the organism? Ive always thought that mobile genetic elements like transposons were regarded as selfish DNA. Introns also.
I dont understand what the "breakthrough" is here.

Come to think about it isnt ALL DNA selfish?

Exactly the point. I never liked the term, and Richard talks about it in the prefaces to the more recent reprinting. There can't be anything selfish or unselfish about a blind process - natural selection.

I may be wrong, but RD has some regrets of the word choice, and it looks like this article has misunderstood its application to this discovery.

EDIT:
I own the book in both paperback and hardcover version but haven't read it yet, I need to finish other books first. lol From what I understand from quickly looking at some pages is that the genome (replicator) selfishly uses the organism (vehicle) purely for the purpose of passing itself on. Not conciously, of course. lol

would be better as something like...

Also...

Is improved a little as...

I agree, this is very poorly written and thank you phil rimmer, the rephase helped.

Two points.
1. The writer uses the term selfish way too loosly. RD goes to great length in the preface to the 30th anniversary selfish gene edition to clear up the misunderstanding and misquoatations of this concept and it is articles like this which do no good to add clarity to the metaphor.
2. Perhaps being over critical but from a genetics point of view, the gene is more properly named in terms of it directly observed phenotypic effect. I.e. the gene controlling the mating type of yeast is known as mata and the HOX gene controlling the appearance and position of the eye in drosphilia is the eyless gene(cuz fly is eyless when gene is mutated). On this points should the article not read, new discovery proves 'sterile gene' exists. Not as catchy though :)

 avatarExcellent news! I wonder if we will hear from Richard on this discovery.

For those above who have some trouble with the word 'selfish' as applied to genes, or the significance of this particular discovery, your questions will most liked be entirely cleared up (and your outlook on life entirely altered) after you have read 'The Selfish Gene.' The example of sterile worker insects takes a prominent place in the book, and I think you will be quite satisfied.

'The Selfish Gene' will probably be ranked among the most important books you have ever read once you finish it. It certainly is for me.

29. Comment #197337 by Aidan86 on June 21, 2008 at 7:16 pm

Doesn't this article miss the point of Richard's book? I thought the main thesis of the Selfish Gene was that natural selection occurs at the level of the gene, not that there is some specific selfish gene in our dna. This might be interesting research, but it's a different idea really, as far as I can tell.

My guess is that Peter Oxley and Graham Thompson are rolling their eyes and regretting the whole affair.

31. Comment #197380 by Konradius on June 21, 2008 at 11:59 pm

To me the most damning line in this article is the last. The point of the book is that ALL genes are selfish. If they're not they get selected against and disappear.

I would have loved to get some actual understanding of the finding, but that seems to have been omitted from this article...

Oh yes, and then the remark about fundis thinking evolution is evil.

Well, yes, evolution *IS* evil! Evolution is just as evil as earthquakes, volcanoes and other natural occurrences that one usually does not personify.

Getting a child with a genetic defect is an evil occurrence, and one that we should try to prevent. However this is natural selection at work. That is, your child will be selected against!

The remedy is to understand evolution and limit its effects. And this is what we should stress. Yes evolution is evil and you're helping it if you deny that it exists!

33. Comment #197387 by Stacey on June 22, 2008 at 12:25 am

I too hope Prof. Dawkins will respond and give details. I was just getting started when the whole piece ended!

Just as an aside, but still relevant to the whole concept of 'selfish' gene, it raises a specific point that should be considered when discussing and explaining things of science to the layman, especially when you consider most laymen have a long history of religious brainwashing.

I think many of the terms and descriptions may be intended as helpful but they genuinely confuse people and give the wrong idea. Consider that most laymen unfamiliar with natural selection at all, or evolution, tend to presume that evolution is a causal agent in competition with a god, so that is a communication barrier right off. Then it crops up again in natural selection when they describe events such as, *nature favored this animal's ability to stay warm and it was rewarded by having more mates, etc* which is always coming off as personification to the layman - as if nature is also a causal agent taking sides between this one and that one, on a material ego sort of basis...if not arbitrarily.

When I read The Selfish Gene, I understood the proper context without a problem but only because I'd already been introduced to things of science and gotten a feel for the "lingo" and use. Talking cold to a religionist or layman, using these sorts of terms is implying a competitor to a god, and well, they're used to their god and familiar with it, their stories make more sense, and some indifferent "cruel" female entity such as nature selecting animals arbitrarily is a losing concept in competing concepts.

While it is not technically biological, I tend to use the process of mating to conception to pregnancy to birth to infancy et death to help explain the concept of evolution, and as for the "transitional stages" those are far easier to get across when you can show a fetus as compared to a 65 year old man - they get it far easier in that sort of context. Also helpful is using the WalMart example - and how a particular shopping style has come about from the first entry into the store - learning the layout, the various items' locations, what times a checker is likely to be open, when traffic is easy for parking - that sort of layman's version and show how over time the changes have polished up a style that has succeeded, been favored over some other - and thus the other went extinct.

It's a dumbed down version but it is very helpful for those who find the whole topic so alien and remote and "out of their league" but are threatened by the idea of some comepeting entity doing what they already figure god was doing, so no need to shift.

Perhaps if we consider the religious methodology in terms of natural selection, we could reply to them that if evolution was not real or didn't exist, they'd still be stoning babies and sacrificing goats. Evolution has taken place in all religions as one form or method was replaced by a more productive one, and the old ways have gone extinct.

Genes may function for the survival of the gene, but soon as you say selfish, people automatically bristle up that the gene is *selfish* in the ego sense. Science could help this cause tremendously by working out a less threatening manner of description - something they can relate to without necessarily dumbing down.

You are entirely right that there is much else to complain about. Genes "wanting" to do things makes me squirm.

The skill in writing accessible science articles without introducing too many unknown terms for the lay person is not gifted to many journalists. You would have thought that Phys Org could field a better journo than this, though.

35. Comment #197410 by stephenray on June 22, 2008 at 2:11 am

There isn't 'a' selfish gene, you journalist turkeys. They are ALL selfish. The point is that genes are only 'interested' in replicating themselves; they have 'no thought' for the survival of the planet, of the species or even - after procreation - of the individual.

What has been discovered is the 'selfish gene' in the bee genome which, unlike most selfish genes, doesn't even care about replicating itself, because it 'knows' that a copy of itself is replicating like buggery in the queen.

The reason why this is important is that impinges on the criticism that many (admittedly, those hampered with defective intellectual development) make of The Selfish Gene because they think it is about 'how genes make us selfish', when that is not the thesis which RD advanced.

 avatarForget the article, which admittedly is garbage.

The importance of this is that Oxley was able to isolate the part of the genome which contains the gene regulating workers sterility.

This proves in practice Richard's ideas about reproductive altruism as he described it, and pretty much settles in his favour the controversy with the group selection bunch.

Those confused by the word "selfish" should actually read the book.

The confusion over the term selfish is perpetuated in the most unlikely places. Molecular biologists In labs everywhere and in modern textbooks often refer to selfish DNA when the DNA in question does not code for a protein or doesn't have any known function and is perceived to be simply "hitching a ride".

I must re-read the book. I read it twenty odd years ago and was the major catalyst in my career move from electronics to the life sciences. I lost my copy years ago so now off to get another.

 avatarThat's right, Steve, but he is an advocate for group selection, both in social insects behaviour and in his interpretation of religion.
In either case, he fails to provide satisfactory evidence to support his claims.
I may be missing something, feel free to correct me.

Here is a quote, which doesn't format well, being from pdf. I apologise.


Even though group-level adaptations can evolve in theory, the
second part of the consensus concluded that they seldom do so
in the real world, because group-level selection is almost
invariably weaker than individual-level selection. This con-
clusion was so widely accepted that group selection became a
pariah concept, taught primarily as an example of how not to
think. The theoretical justification for individualism in psy-
chology seemed secure.
Nevertheless, much has happened in evolutionary biology
during the last half century (Wilson & Wilson, 2007). The first
part of the 1960s consensus remains valid: Adaptations at any
given level of the biological hierarchy require a process of natural selection at that level and tend to be undermined by
lower levels of selection. The second part of the consensus has
proven to be erroneous: Higher-level selection can be a sig-
nificant evolutionary force, one that sometimes even dominates
lower-level selection, causing the higher-level unit to become an
organism in every sense of the word. Ironically, given group
selection's previous pariah status, it is now the concept of groups
as organisms that stands on a firm scientific foundation. More-
over, it is likely that human evolution represents such an evo-
lutionary transition, and this has profound implications for
psychology and all other human-related subjects.
When between-group selection dominates within-group selec-
tion, a major evolutionary transition occurs. The social group
becomes a higher-level organism and the members of the group
acquire an organ-like status. This idea was first proposed to
explain the evolution of eukaryotic (nucleated) cells, not by
small mutational steps from prokaryotic (bacterial) cells, but as
highly integrated symbiotic associations of bacteria. The idea
was then generalized to include other major transitions, in-
cluding the first cells, multicellular organisms, social insect
colonies, and even the origin of life as groups of cooperating
molecular interactions (Maynard Smith & Szathmary, 1995).
Major transitions have a number of hallmarks: First, they are
rare events in the history of life. It is not easy for between-group
selection to dominate within-group selection. All species of
eusocial insects (e.g., ants, bees, wasps, and termites), for ex-
ample, are thought to be derived from only 15 original transitions
from solitary insect species. Second, major transitions have
momentous consequences once they occur. Individuals and
uncoordinated groups are no match for the new superorganisms,
which quickly become ecologically dominant...

 avatarIt's interesting that this team is getting close to isolating the gene for worker sterility, but the references to Dawkins' The Selfish Gene seem a bit confused.

As far as I understood, the main message of TSG was that it can be useful to consider that all genes are in a sense 'out for themselves', and not that there are some selfish genes which are out there to be discovered.

 avatarbitbutter,

that's right. This discovery simply proves that worker sterility is the expression of a gene which favours its own "selfish" propagation through reproductive altruism, and that the latter isn't the result of group selection.

Can someone refresh my memory on bee sexual behaviour as well.

I was fairly sure that some female honey bees don't reproduce in some sort of "elective" fashion, or through suppression by the Queen.

In that they can become fertile when the queen is absent, or under other circumstances. I seem to remember that the behaviour is the kind of complex mess you'd expect from evolution (or a noodle-ly creator god). Of course that might just be our sexually sophisticated European honey bees, other genera of honey bees may behave differently.

I remember thinking at the time that someone had spent a LONG time watching honey bees VERY closely, in figuring out the complexity of bee reproduction - I guess some people like honey even more than I do.

It is all a lot more complex than one queen - lots of men who do nothing - which is the simplified version we got taught at school. Which is both rather boring, and so far from the magnificent truth that I felt short changed when I learnt more.

Indeed! A friend of mine, when asked to borrow his copy of "The God Delusion," often instead convinces the borrower to read "The Selfish Gene" instead. Any thoughts on which might do a better job 'converting' someone?

I have read "The Selfish Gene," but not "The God Delusion," so I think I am exempt from guessing.
