April Wright recently published a cool paper looking at how to bring morphological analyses of evolutionary relationships into the Bayesian realm. This is her take on it – enjoy! Author Bio: My name is April Wright, and I’m a graduate student in David Hillis’ lab at the University of Texas at Austin. I’m largely interested in the estimation and use of phylogenetic trees to ...[Read More]

Steampunk takes evolution to the next level
Sharing this purely because it’s amazing. Hat-tip to John Hutchinson for sharing!
Citizen science in ecology and evolution? Sounds apps-olutely fantastic.. *tumbleweed*
There’s a lot of talk these days about science communication. Some people spend their lives debating the differences between outreach, public engagement, and science communication, and how they all mean different things. As a scientist, and I’m quite sure I can speak on behalf of the entire community, we don’t give a toss what you call the model – let us interact with peopl ...[Read More]
The greatest story ever told, by fossils
A lot of recent(ish) posts featured on this blog have been about the evolution of flight and feathered dinosaurs. I promised to kick this habit, and write about something different, but this video by Carl Zimmer adds a really nice narrative to the story and is quite a nice little overview for anyone interested. If you have any questions about bird-like fossils, feathers, their function, or dino-bi ...[Read More]
Om nom nom
What comes to mind when you think of dinosaur interaction? Large carnivores chomping on unsuspecting little ornithopods? Ceratopsians jousting for their next mate? Large hadrosaurs tenderly mothering their cute newborns? There are many possible images of community-level dinosaur interactions, and there is a host of evidence out there that take dinosaurs beyond the bones and breathe new life into h ...[Read More]
How did birds get their wings?
How many fingers do you have? Hopefully, 5. Do you think that’s the normal condition for all animals? Do you think that’s air you’re breathing right now? … OK, so I watched the Matrix last night, but still, do you think all tetrapods (dudes with 4 feet, including you, and anything else with four flippers, wings, or feet) have 5 digits on each limb? Actually, there’s a pattern within tetrapods of l ...[Read More]
Progressive Palaeontology, Leeds 2013
Progressive Palaeontology (ProgPal) is an annual event where early career researchers get to demonstrate their research to an equivalent audience in a reasonably informal atmosphere. It’s also renowned as a mega p*ss-up, as everyone knows palaeontologists are chronic alcoholics (hence the dinosaurs with feathers hypothesis). This year, it was in the vibrant and cosmopolitan northern UK city of Lee ...[Read More]
The early evolution of dinosaurs
Dinosaurs. What springs to mind when they’re mentioned? Colossal, towering sauropods? Packs of feisty feathered fiends? Or huge herds of hadrosaurs, chomping their way across the plains of long-lost worlds? Most, including myself, will automatically default to any one of these images when dinosaurs come up in conversation (what, you mean it’s not that frequent for normal people?) But w ...[Read More]
Fly, my pretties, fly!
The origin of bird flight is one of the greatest stories evolution has ever told us in the history of life on this planet. To imagine how organisms that once ran around on the ground have descendants that soar through the skies is truly phenomenal, and represents a truly great leap in increasing the awesomeness of these animals. The secret of how it came about though is hidden away in the fossil r ...[Read More]
Did dinosaurs lactate..?
The fossil record is brutally frustrating; it mostly preserves only vestiges of deaths long past as body fossils, with occasional glimpses of life being gleaned from their surroundings and any trace fossils, or activity fossils that we might find. One question palaeontologists have long been seeking the answer for is how good were dinosaurs as parents? Modern birds are descended from dinosaurs, an ...[Read More]
