The hip-hop Richard Dawkins?

That's the title of a review article in the current issue of Trends in Ecology and Evolution (TREE), the highest-cited peer-reviewed science journal in evolutionary biology. The review was written by the journal's editor, Dr. Paul Craze, who just emailed me to say that the review is now the number one most-downloaded article on the TREE website. I was going to post a link and invite you all to read it, but like most science journals they charge by the article and if you aren't a subscriber it would cost you $31.50 to download the pdf! So here's the full text, which I have extracted for purely educational purposes. I like to joke in my show about how it's the first-ever scientifically peer-reviewed rap, but up until now that was a pretty tongue-in-cheek statement. Now it's literally true. Enjoy!

The hip-hop Richard Dawkins?

Evolutionary biology and poetry might not seem remotely suited to each other but nonetheless, some have experimented with bringing them together. Erasmus Darwin, grandfather of the more famous Charles, famously wrote his work on the transmutation of species in the form of verse [1] and much more recently, in the days before impact factors gathered enough tyrannical power to put a damper on anything the least bit quirky, this very journal re-published some of the evolution-inspired poems written by friends and colleagues of J.B.S. Haldane to mark his 60th birthday [2]. Suffice it to say, both works are of more note for their intrinsic interest than their literary merits.

Perhaps this just shows that evolutionary biologists are not much good at poetry and poets don’t see anything in evolution to inspire them. The first of those sentiments might well be true but the second has now been comprehensively disproved. Canadian rapper Baba Brinkman’s The Rap Guide to Evolution is an intelligent, lyrical, witty collection of performance poetry that also manages to be an accurate, popular-science discussion of modern evolutionary theory and its wider implications. Those of you with an aversion to rap music bear with me; this is not rap as you might know it. This is rap with an intelligent twinkle in its eye. It is rap with warmth and humanity, far removed from the stereotype of the style as aggressive, violent and divisive. It is also rap that doesn’t simply use its subject matter of evolution as an amusing gimmick but rather draws on modern Darwinism with accuracy and insight. The accuracy is ensured by instigator of the project Mark Pallen, Professor of Microbial Genomics at the University of Birmingham, author of The Rough Guide to Evolution [3], making this the first rap album ever to be peer reviewed (as Brinkman is justly fond of telling his audiences). The insight I’m sure is Brinkman’s own, particularly when he becomes self-referential and cleverly uses the process of writing and performing rap as an example of the evolutionary process on Performance, Feedback, Revision or of sexual selection on Hypnotise.

In common with many works of popular evolutionary biology, there is a bias towards those topics that appeal directly to our primate brains (Hypnotise, Sexual Selection and Sexual Selection Theory all exploiting that obvious, perennial primate favourite, for example). But given the wide and unusual audience the music is likely to reach, that can hardly be a criticism, particularly when the material is handled by someone with the wit and humanity of Baba Brinkman. For example, in Brinkman’s hands a rap inspired by a song promoting Black Nationalism (Dead Prez’s I’m A African) becomes a plea to recognize the unity of our common descent: genetically we are all Africans, which, in Brinkman’s words, makes I’m A African the most ironically inclusive song ever written. What makes this much more than well-intentioned humanism is the frequent reference to the scientific evidence. To continue with I’m A African, there is reference to the fossil and mitochondrial evidence for the Out Of Africa theory, all in rhyme and with a rhythmical beat. And again in Group Selection there is no vague philosophizing but instead the sometimes difficult ideas about altruism and cooperative behaviour are faced head on with exuberant openness. Find me another rap album that references endosymbiosis, the evolution of multicellularity, Dictyostelium and cheater detection, let alone one that uses this evidence to such high-minded effect or includes suggestions of further reading in the sleeve notes.

I have just two criticisms. Once or twice there seems to be an equating of fitness with physical strength. It would be a pity if such an insignificant part were quoted out of context, especially since Brinkman eloquently describes the complexities of fitness elsewhere on the album. My second criticism is not strictly a criticism at all. I wonder if the Rap Guide will remain something enjoyed by those of us in the know, those who already get all the jokes, the allusions to evolutionary theory and the references to biologists. As Brinkman himself regrets with a knowing wink in Sexual Selection; while educated, thinking, older women wait to talk to him after his performances, their daughters and granddaughters are at gangsta rap gigs, being exposed to a very different set of views. There is an opportunity here to communicate good science to those who might never think of it as having anything to do with them. Fortunately, Brinkman seems well aware of this and is working tirelessly to promote the work as widely as possible.

I will leave you with some thoughts on the album’s last track, Darwin’s Acid, in which Brinkman argues against the claim that an acceptance of evolution means an end to compassion and personal morality. It is quite the opposite, his rapping tells us over a gentle musical background: the choices we make directly influence the evolution of culture, current biological fitness and the composition of future generations. In Brinkman’s vision, Darwinism becomes the ultimate argument for personal and democratic morality and his humanistic version of directed reproduction means that "refusing to sleep with mean people" gives us a good shot at utopia. While the complexities of inheritance and human mate choice make this less simple in practice, such a sincere argument for a Darwinian morality at least points to the absurdity of claiming that an evolution-based worldview means the collapse of society into violence, selfishness and greed. To Brinkman, this personal responsibility combined with unity of common descent is the grandeur Darwin saw in the evolutionary view of life. With humility, Brinkman leaves the last word to Darwin with a reading by Richard Dawkins of the famous last sentence of The Origin of Species, in which there is grandeur and the evolution of endless forms most beautiful [4]: perhaps the one sentence above all others that shows evolutionary biologists might know a thing or two about poetry after all.

So when the review by Olivia Judson came out a few weeks ago in the New York Times, one of the main points of contention in the comments section was over my claim (in my online bio) that I have personally planted over one million trees. A number of commentators
cried foul (starting at comment #13 and precipitating from there), liberally exercising their cheater-detection instincts by opining that such a thing was impossible and I had clearly blown my credibility by making outlandish claims. The truth is I had indeed made the claim without knowing the exact number of trees I had planted, so yes, it was a rough estimate. All I knew for sure was that I planted for seven full seasons and six partial season and I was pretty fast with a shovel back in the day (my best day was 4400). I knew it was pretty damn close to a million, but what if I had claimed "over a million" and it turned out to be a few thousand shy? The shame would have been unbearable.

So today I went to the head office of Brinkman & Associates Reforestation in New Westminster to sit in on a meeting there, and I asked the head of payroll, a dear old family friend named Kitty Ypma and an excellent accountant and book-keeper, if she would be so kind as to pull my employee files going all the way back to when I planted my first tree at the age of 15 in 1994, and tally up my yearly totals to see whether or not I was full of it. Well, I just got the email from Kitty a few minutes ago confirming that my total trees planted from 1994 - 2010 is precisely 1,046,105, so thankfully I do not owe the New York Times or anyone else a contrite retraction, (though I admit I was holding my breath!)

Speaking of planting, I had been planting with my brother's crew for the past few weeks, but I left a week ago to fly to New York for my appearance on the Rachel Maddow Show last Friday, and when I returned Erik informed me that there was a truck broken down and he needed to lay someone off until it was fixed, so I volunteered. So I've been holed up in Vancouver for the past couple of days working on my Beowulf adaptation for the Edinburgh Fringe and writing video treatments for the Wellcome Trust
Rap Guide to Evolution videos, but tomorrow I'm heading back out to camp for another week or so of planting before I fly to the UK for the summer festival circuit.

By the way, at the camp party ten days ago we filmed a music video with Smoky Tiger for our song "The Road Northwest" so look out for that on my youtube channel in a few weeks, directed by Syd Woodward at If you aren't familiar with Canadian tree-planting sub-culture, check out the video for Smoky Tiger's anthem "The Tree Planter's Waltz" which we filmed last year in camp. 'Til next time, stay vigilant!
