What science is all about

All which is between “~~~” is from Jerry Coyne.

I have sometimes written that evolutionary biology doesn’t have much practical value in medicine or other areas impinging on humanity’s material well being. Here is one example of what I’ve said. However, my friend and colleague David Hillis at The University of Texas in Austin — who played a big role in trying to make the Texas State Board of Education teach real science – has taken exception to my view. I asked him to let me know how he thought that evolutionary biology had been of use in medicine, and he wrote me an email with his answer, which he’s given me permission to post. He’d wants to emphasize that it’s an off-the-cuff response rather than a comprehensive reply, which of course I appreciate; but I think it’s worth posting:

OK, here are just a few examples from the thousands that are in the literature, off the top of my head:

Using positive selection to identify the pathogenic mechanisms of HIV in humans: PNAS 102:2832-2837 (one of many such studies that are now appearing and are using positive selection in pathogens to identify pathogenic mechanisms).

Using phylogenies and positive selection to predict which currently circulating strains of influenza are most likely to be closely related to future flu epidemics: Science 286: 1921-1925.

Using evolutionary analyses to track epidemics in human populations: many examples that have wider health implications, but our study of transmission in a forensic case was an interesting example with a specific legal application; PNAS 99:14292-14297.

Using evolutionary analyses to identify new disease outbreaks: new examples in every single issue of Emerging Infectious Diseases.

Using phylogenetic analyses to identify whether polio outbreaks are from native circulating viruses or from reverted, escaped vaccines (which tells health workers which vaccines to use in these areas to eradicate disease): see review in Bulletin of the World Health Organization, Vol. 82, No. 1.

Identifying changes in sodium channel genes that are under positive selection for TTX resistance, which has led to understanding the function of human diseases that are caused by the corresponding substitutions in human sodium channel genes: Mol. Biol. Evol. 25(6):1016–1024. (I included this one to show that all of the examples are not from virus work; this is the original evolutionary work from Manda Jost and Harold Zakon, with our collaboration, but there has been follow-up on the understanding of human diseases that are produced from these same mutations, now that they have been replicated by in vitro mutagenesis)

This just scratches the surface. I think there are now more papers that use evolutionary methods and analyses in the human health literature than all other areas of biology combined. I think it is crazy to not acknowledge the numerous and important human health applications of evolutionary theory and methods.

Well, this is good enough for me–I gladly retract my earlier opinion that evolutionary biology hasn’t been of much use in medicine. Thanks, David.

Imagine a creationist making the claim that evolution doesn’t have much practical value in medicine (something with which I am hugely surprised Jerry Coyne ever said) and then retracting it when presented with counter-evidence. It would never happen. Creationism rejects all principles of science.

Another victory

People who aren’t blatant, proud bigots got another victory.

Iowa’s Supreme Court legalized gay marriage Friday in a unanimous and emphatic decision that makes Iowa the third state — and first in the nation’s heartland — to allow same-sex couples to wed.

Iowa joins only Massachusetts and Connecticut in permitting same-sex marriage. For six months last year, California’s high court allowed gay marriage before voters banned it in November.

The Iowa justices upheld a lower-court ruling that rejected a state law restricting marriage to a union between a man and woman.

The county attorney who defended the law said he would not seek a rehearing. The only recourse for opponents appeared to be a constitutional amendment, which could take years to ratify.

“We are firmly convinced the exclusion of gay and lesbian people from the institution of civil marriage does not substantially further any important governmental objective,” the Supreme Court wrote.

I guess Iowa isn’t part of “real America” anymore.

This is very good. Religious bigots oppose gay marriage because they believe their sexual desires are superior to those of others. They have no good reasons for such inane beliefs. They have no place in the ever-increasing morality of an ever-increasing secular culture.

Oh, you guys

I get lots of odd things searched on this blog. It all shows up on my stats page. For instance, someone believes “sex toy fucking” or some variant thereof is either 1) hilarious or 2) will one day yield fruitful results. Keep trying, my friend, but I think Google will give you faster results.

Other than that most searches are “natural selection not random” or something similar. The post being searched is one of my post popular pieces. I believe it’s being passed around in some email because I see a link to inboxes, but I obviously can’t look at anything there. Of course, I’m not the most tech savvy, so I say this with great tentativeness. (If anyone is interested, this is my most popular post of all time.)

Anyway, I’ve recently come across my favorite search result so far.

Surprise me with some good ones. I may make a whole separate page for these things.

Troopers troopers

I have updates for two previous posts. The first is about that Dallas cop – Robert Powell – that stopped a family from seeing their dying relative. He pulled a gun on these people. Think about that: a vehicle slowly runs red lights, puts on its hazards, and pulls into a hospital parking lot. What’s your first thought? Well, if you’re normal, it’s that there’s an emergency. If you’re an almost surely racist, hillbilly cop, it’s to pull a gun out on t’em t’ere niggers. That’s what Powell did, among other things. He has resigned.

“I made this decision in the hope that my resignation will allow the Dallas Police Department, my fellow officers and the citizens of Dallas to better reflect on this experience, learn from the mistakes made, and move forward,” Powell said in a statement issued through his lawyers.

No, he wants to ease his legal situation as best as possible and he knows he’s going to be fired anyway. Understandable move, but he’s lying.

My second update is about my run-in with some officer at the Augusta Police Department who had no idea how the Maine Freedom of Information Access Act works. The Capital Weekly (a local, weekly paper) has asked me to do a first person write-up of the incident. It will not be kind to the offending officer – Lt. J. Christopher Read.
