Tattoo Monday V

This week we have a few of the recently available phylogenetic tree tattoos for you, following on from the previous posts: Tattoo MondayTattoo Monday IITattoo Monday III, and Tattoo Monday IV. We even have the first tattooed feet. The tree on the middle right is somewhat of a worry, if you care about phylogenetic accuracy. The circular designs re-appear in Tattoo Monday VII.

While it seems true that the probability of observing a new phylogenetic-tree tattoo decreases with time, this is apparently an exponential decay, so that the probability approaches zero rather slowly. It might, of course, be a pareto (power law) distribution instead, which never reaches zero, thus keeping Carl Zimmer employed producing endless supplements to his book (Science Ink: Tattoos of the Science Obsessed).
