Explanation
This comic features a running theme in the xkcd comics, Beret Guy's naive and/or odd ways of thinking. In the beginning of the comic, Beret Guy shows Megan what he believes to be a tree, and explains that it grew there because he placed magic beans in that spot yesterday. This is a reference to the fable "Jack and the Beanstalk", where the protagonist plants several magical beans he acquired, resulting in a beanstalk growing which ascends into the atmosphere. Megan, however, tells Beret Guy that the "tree" is actually a cell phone tower. Beret Guy disagrees, pointing out that it has branches, to which Megan tries to explain that this was in an attempt to make the towers look like trees. She gives up, however, as Beret Guy has already begun climbing the tower, or because she fears that giving this explanation would only add fuel to the fire that is Beret Guy's imagination.
Later, Megan complains that her cell reception has disappeared. Beret Guy responds by saying that he had to cut down his "tree" because there were "scary giants with yellow helmets" in it (presumably, construction workers). This mirrors, again, the "Jack and the Beanstalk" fable, where the protagonist has to cut down his beanstalk to prevent the giant, whose lands the beanstalk connects to, from climbing down and chasing him. In reality, the "giants" were probably utility workers.
The title text suggests that, over time, trees will evolve to start looking more like cell phone towers in a form of mimicry in order to avoid people cutting them down. Mimicry is where a creature copies the appearance or behavior of another in order to confuse predators. In this scenario, the more defenseless trees attempt to mimic cell phone towers, which have the defense of people not wanting to cut them down or they would lose cell service (and likely a significant amount of money through fines) and because of society's general respect for the property of others, as well as the dangers of electrocution or radiation. This is similar to the counting pine, a tree in Terry Pratchett's Discworld series that evolved to display its age with numbers on the outside (in the bark) in the hope that humans would not cut it down and count its rings. Of course now humans hunted it down trying to find a tree with numbers that would fit their house number instead, thus quickly rendering the trees almost completely extinct. (See the tribute to Terry in 1498: Terry Pratchett).
Convergent evolution deals with multiple species acquiring similar characteristics to fulfill their role (such as dolphins and sharks both having a streamlined shape to swim fast) due to the species' common need to adapt to similar environments or tasks. Randall uses the term to describe the convergence in the appearances of cell towers whose design has "evolved" to include tree-like branches and trees which he predicts will evolve to resemble cell phone towers. Each of these "evolutions" would be for the purposes of camouflage, although the cell towers "evolve" by human design for purely aesthetic reasons and the trees would evolve naturally for self-preservation. This would therefore not be a true example of convergent evolution. It more closely resembles Batesian mimicry, or the evolutionary process by which a species remains noticeable, but treated as something it is not.

Discussion
Explanation may benefit from adding that cell phone tower appearance has evolved to be more treelike. [Comet] 05:07, 26 August 2015 (UTC)
I know XKCD isn't really heavy on proportions, but the heads look slightly bigger in all but the last panel. It kinda makes both characters look like children initially. -Pennpenn 108.162.250.162 07:02, 26 August 2015 (UTC)
Could the "giants in yellow helmets" be a reference to Clash of Clans? Aruta (talk) 10:13, 26 August 2015 (UTC)
- It's not Batesian mimicry
Evolutionary biologist here: it's not Batesian mimicry. It's mimesis.
Archetypal mimesis is a stick insect looking like a twig, because predators don't care about twigs. It's the same thing here: trees looking like telegraph poles, because people don't care about telegraph poles.
It has nothing to do with the telegraph pole's defences (what would that mean?). Without defences, you can't have Batesian mimicry. 141.101.98.176 11:29, 26 August 2015 (UTC)
Cell phone towers evolved to look like trees to defend themselves against people who would object to their presence on grounds of visual blight. http://www.wired.com/2013/03/dillon-marsh-invasive-species/ [Comet] 22:41, 26 August 2015 (UTC)

I think that cell towers do have defenses. When you wound them, they start emiting utility workers, policemans and lawyers. (I'm sure the operator will get message if BTS is disconnected.) -- Hkmaly (talk) 12:49, 26 August 2015 (UTC)
At the time of this comic, there was a website devoted to cell towers that were camouflaged to look like trees. The site was FraudFrond.com and had several euphemisms for them. Fake firs, sham shrubs, bogus botanicals, and my favorite, counterfeit conifers.
I don't if it is relevant but there is an old MSX game called magical tree that displayed the tree in side view in a very similar way. http://www.mobygames.com/game/msx/magical-tree ZeroA4 188.114.98.202 (talk) (please sign your comments with ~~~~)
- That is a striking resemblance and an identical name. Makes me wonder if it was an inspiration. 108.162.241.148 05:36, 27 August 2015 (UTC)
The third paragraph needs amending. "...attempt to mimic cellphone towers" implies conscious evolution, and the reference to the tower's "defenses" is a relic of the Batesian mimicry reference. What I'm guessing is happening (I'm not an evolutionary biologist) is that trees with a slightly more towerlike appearance are slightly less likely to be cut down by predatory Beret Guys, and will survive to pass similar traits onto their offspring, and over millions of years certain lineages of celltowertrees will increasingly resemble treecelltowers built by humans in turn to resemble them. The claim that this is a "standard textbook example of convergent evolution" is tongue-in-cheek more than facetious; a real example of it ought to be used rather than the Terry Pratchett reference, which seems to illustrate conscious evolution.141.101.99.108 17:00, 26 August 2015 (UTC)
- Original transcript
Randall's original transcript (no changes by me) is this:
- [Beret guy excitedly points to a pillar about a meter across. There's a sign on the side. Beret guy is pointing it out to his friend, Fancy Haircut]
- Beret: Check it out! I threw my magic beans on the ground here yesterday, and this big tree appeared!
- [Now in silhouette we see the pillar is several hundred feet tall, covered in antennae, and the figures are as ants in its shadow.]
- haircut: that's a cell tower.
- beret: no way-- it has branches! See? I'm gonna climb it!
- [Beret guy begins to shimmy up the side of the pole. Somehow. With impressively powerful thighs I guess.]
- haircut: No, they just put those there to make it look-- ...never mind.
- [Later...]
- haircut: Why do I have no signal?
- beret, with an axe: there were scary giants with yellow helmets in that tree! luckily, I cut it down before they ate me.
Is Megan "Fancy Haircut"? --Dgbrt (talk) 18:22, 31 August 2015 (UTC)
