Document Evolution: 24 myths and misconceptions

If you think you understand it, you don't know nearly enough about it

It will soon be 200 years since the birth of Charles Darwin and 150 years since the publication of On the Origin of Species, arguably the most important book ever written. In it, Darwin outlined an idea that many still find shocking – that all life on Earth, including human life, evolved through natural selection.

Darwin presented compelling evidence for evolution in On the Origin and, since his time, the case has become overwhelming. Countless fossil discoveries allow us to trace the evolution of today's organisms from earlier forms. DNA sequencing has confirmed beyond any doubt that all living creatures share a common origin. Innumerable examples of evolution in action can be seen all around us, from the pollution-matching pepper moth to fast-changing viruses such as HIV and H5N1 bird flu. Evolution is as firmly established a scientific fact as the roundness of the Earth.

"If you think you understand it, you don't know nearly enough about it"
I know what the writer means, but i think this comment encapsulates whats wrong with the way science is sometimes presented in the public arena. It is intepreted as "you lowly peasants should not even bother to try to understand important scientific concepts". I dont think Darwin or Dawkins would agree, or why have they written books targetted at lay audiences?

Small question.
W/in t text under t 1st heading "Everything is an adaptation produced by nat. sel." it states "Homosexuality mite be linked to gene variation that increase fertility in females"

Does not this mean that t sisters, mothers and t odd female offspring of gay men should tend to be more fertile than that of non gay men?

I have never heard of any such thing

 avatarFascinating.

I have recently been thinking that rather than having articles and debates on "evolution vs. creation," it might be more useful to put our energies into having articles like this one that simply explain evolution. Remember the wonder you felt when you first started to understand evolution? The next time you are about to get in the old "e.v.c" debate with someone, maybe try taking a time out to just explain to them the basic ideas. Try to make them see the beauty rather than shoot down their ideas. (If anyone tries this, let me know about your results!)

The subtitle echoes a bumper sticker I thought of (which could perhaps be made a bit more catchy):
"Don't believe in evolution? Maybe you just don't understand it."

Must say that i was bored about it, i was learning all the science stuff in school and you just tend to learn it and get on it with it.

I think this is why it's so important to keep ID out of the classroom. If i'd had mixed signals maybe i'd have been more resistant to it rather then just accept it as fact (I know this runs in parrallel with indoctrination but..). In the same way i've never checked how accurate WWII was, it was presented as fact and i have had no reason since to challange the fundamental facts.

In response to the article, my opinion is: The Christians of America have no interest about the facts of life on planet Earth. They care not about proven evidence. Christians are only interested in the adherence of everyone to their fantasies and imaginary saviors.

Lets face it. There is almost zero hope for planet Earth.

Today, I listened to police, lawyers, and policy makers all of whom are having problems with the prospects of charging (let alone convicting) anyone in the Texas polygamy scandal. Repeatedly, I kept hearing stuff about religion, sects, and beliefs. It appeared that the social workers have their hands tied by the courts.

If America cannot convict the religious of child abuse because the beliefs of the religious preach the practices, then how can any of the religious (or conservative policy wonks) ever understand The Law of Evolution?

Hey, if religion does wrong, it is okay as long as it is faith-based. With the size of that Texas religious compound and community, I would guess the money for all of structures were flowing in even during the Texas governorship controlled by George W. Bush.

This is what I learned today.

I wish Pat Condell would do one of his fiery articles on religion in America. Pat, we need you.

12. Comment #163040 by Mitchell Gilks on April 17, 2008 at 9:50 pm

 avatarHomosexuality isn't restricted to males, and there is absolutely nothing that says homosexuals can't reproduce or have offspring. In case you haven't noticed, a good chunk of the majority of people are unattractive. It is not strange, or in anyway unheard of for people to have offspring with people they are not attracted to.

Because of the stigma against homosexuality by society, straight people tend to be adverse to the idea of even getting near a member of the same sex, untop of not being attracted to them. I am not sure, but I doubt this translates to the other extreme. I don't think there is a social stigma against homosexuals being near or having sex with members of the opposite sex, so I don't see a reason why they would be anymore adverse to the idea then they would be of having sex with anyone they don't find attractive. I could be wrong about that last part though, and it likely varies between people.

Sorry dogfire, can't blame this one on W. I'm pretty sure the majority of the people living in that compound came from Colorado City, Arizona, and I'm almost positive that is where most of the money came from. The FLDS has been fleecing the state of Arizona out of money for the past 70 years.

The compound in Texas was supposed to be a new "kingdom" for Warren Jeffs and his followers. Of course Jeffs got arrested last year for facilitating marriages between underage girls and 40-50 year old men. I haven't been following this story since I got called to active duty last Oct., but a little googling using "Warren Jeffs" and "Colorado City, Arizona" should make for some interesting reading if you are so inclined.

True but irrelevant. What you said was that homosexuals would not have any offspring. This is self-evidently not true.

Take me for example: I'm homosexual, I have a child. My genes (including, for the sake of argument, my "gay" genes) are being passed on.

Homosexually orientated people have always been just as physically capable of producing offspring as bisexually and heterosexually oriented people. Whether they do that by heterosexual sex, turkey baster, etc doesn't change the fact that they are homosexual.

20. Comment #163061 by Greyman on April 17, 2008 at 11:43 pm

Homosexuality does not prohibit mating with the opposite sex, just biases against choosing to do so.

If the genetic contributor in males also causes increased fertility in female offspring then there's a long term cancelling effect.

It would then become a trade off between decreased chance of replication in male generations versus an increased chance of replication in subsequent female ones.

You could imagine a genetic variant that would increase a woman's fertility by more than (say) 10% and have the side effect that 10% of her descendants would be homosexual.

Whether or not the homosexuals produced offspring, the variant would confer a net advantage and so could be propagated by the increased number of reproducing offspring.

From the article:

Most [mutations] make no difference to our bodies, because most of our DNA is useless junk anyway.


It's a little ironic that this article, in purporting to dispel misconceptions about evolution, furthers another.

Even if 'junk' DNA has no apparent morphological, phenotypic effect, that is not to say that it serves no purpose.

Grrr.

This is what happens when the IDiots at Uncommon Descent link to an article.

I'd almost recommend going over there now to see some of the laughable comments. (Some people are even defending Biblical inerrancy.)

Of course, those of us with the faculty of reason are not able to comment on that blog because they screen all the posts. I believe my Uncommon Descent account was blocked merely for linking to http://expelledexposed.com/">Expelled.

32. Comment #163152 by Mitchell Gilks on April 18, 2008 at 3:09 am

 avatarI highly doubt that there are "gay genes". I am unaware of any significant evidence of homosexuality being hereditary. Also, the whole idea of a preference being genetic sounds rediculous to me.

That said, I don't think that heterosexuality is genetic either. Merely sexuality, and sexual preferences, I think are likely developed at a very young age. For whatever reason, 90% aim them toward the opposite sex, while 10% aim them toward the same sex.

I think that the idea that is is genetic is latched unto with vigour, so they can just claim "see, it's not my fault, I can't help it. I was born this way." Without realizing that is a non-issue, and doesn't matter. Even if people just arbitrarily decided to be homosexuals, I still fail to see a rational case to be made why there would be anything wrong with that. I think that too many homosexuals are buying into the complete non sequitur that if they could help it, or even it wasn't genetic, that would be somehow bad.

Now, I could be wrong, it could be genetic, I just highly doubt it. Unless someone can demonstrate evidence of it's hereditary transmission. In fact, I would take any demonstration of the hereditary transmission of any preference, as evidence that at least preferences can be hereditary.

I also don't think that it is a conscious decision, as I don't think that any preference is. They are developed over time, and not something we have control over. Though I really don't see how it would matter in the slightest if we did.

First, well done to new scientist, so many 'rebuttals' (i use this word in the loosest possible term) to evolution stem from a lack of understanding of it, though there will always be a core of people who refuse to accept the facts.
Second, i think MG has a very good point is all that he said, but could it be that there is no 'gay gene' so to speak, but it is certain combinations of genes that may give preference one way or the other?

Is t writer stating that female relitives of gay men are more fertile? Actualy it reads to me like it was a mere hypothisis, one of a few that could explain t presence of "gay" genes. (I realy do not want t start anything on that issue)

I am simply unclear on how much, if at all, t writer is making that assertian.

Ygern: "The comments section on New Scientist are a bit depressing."

Indeed. My favorite is this one:


Physical fields propagating at the speed of light are preceded by nonlocal electric and magnetic potentials.

(http://en.wikipedia.org/wiki/Aharonov-Bohm_effect )

God is the sum of these potentials. Subtle is the Lord.


That's a new one! It's amazing how adept creationists are at sounding scientific without needing to do any actual science. It's all about marketing the meme -- which they've had 2,000 years to perfect.

Great series of articles though -- succinct and convincing.

My wife says that she has read of there being a tendency for female siblings (like NJS was stating) of gay men to feel t need to make up for t lack of procreativeness in their family. She understood it to be more psychological rather than genetic tho.

Along those same lines, she noted a tendency for couples who adopt because of infertility, to bear a child soon after t adoption. T presure is off.

Neither of these is a genetic issue. Tho in t former case, I think it could explain how whatever "gay" gene there is getting put out there.

its an interesting hypothesis or sure, as homosexuality (bisexuality?) seem to be goverened in part by the maternal hormonal conditions??????? and this is determined genetically and influences the mothers own fertility and that of her offspring subsequently.

its amazing that if the connection were true then homosexuality is merely a collateral condition as such, quite amazing, enough of that burn in hell choice nonsense. if true iit would be interesting to see if the most fertile women CAUSE homosexuality.

I must admit its an iteresting thing in its own right how members of one sex supposedly primed to be attracted to he opposite sex do not in the case of homosexuals, and indeed in talking to gay men they seem to be even more 'into' other men than are women, but thats probably just men generally. its almost fetishistic, where the guy will focus very heavily on a particular body trait, im not sure women do that, well not overtly anyway.

I bet a man who considers himself exclusievly homosexual could stil impregnate a woman, given enough coaxing and stimulation, drugs etc (sounds like a party) id be surpised if he couldnt maintain an erection to orgasm esp. with a very attractive woman(I am NOT suggesting that gay men can be made straight, its just that men seem very sexually charged and for known evolutionary reasons).

Damien,

Lets get this, er, straight...

An ideology, or, a base ideas and ideals that go to form the platform of economic or political theories as well as the set of beliefs and characteristics of a particular social group or individual, and somehow this has to with a man sleeping with another man and a woman sleeping with another woman?

Communism, Nazism, Capitalism are all ideologies - soooo, homosexuality would have to be an 'ism'?

'Homosexualism.' or 'Homosexism' Do these word exist? My spell checker doesn't like them.

When we see homosexual penguins, giraffes, dolphins, etc, are we seeing not natural behaviour in animals, but the insidious indoctrination of the minds of the young with their parents ideology?!

Oh course not.
