This sea worm's posterior swims away, and now scientists know how
A research team, led by Professor Toru Miura from the University of Tokyo, shows how the expression of developmental genes in the Japanese green syllid worms, Megasyllis nipponica, helps form their swimming reproductive unit called stolon. The work has been published in Scientific Reports.
Marc Robinson-RechaviThe cool #evodevo paper everyone is talking about: Molecular evidence of anteroposterior patterning in adult echinoderms
"This finding suggests that from the perspective of ectoderm patterning, echinoderms are mostly head-like animals and provides a developmental rationale for the re-evaluation of the events that led to the evolution of the derived adult body plan of echinoderms."

Molecular evidence of anteroposterior patterning in adult echinoderms | Nature
The origin of the pentaradial body plan of echinoderms from a bilateral ancestor is one of the most enduring zoological puzzles1,2. Because echinoderms are defined by morphological novelty, even the most basic axial comparisons with their bilaterian relatives are problematic. To revisit this classical question, we used conserved anteroposterior axial molecular markers to determine whether the highly derived adult body plan of echinoderms masks underlying patterning similarities with other deuterostomes. We investigated the expression of a suite of conserved transcription factors with well-established roles in the establishment of anteroposterior polarity in deuterostomes3–5 and other bilaterians6–8 using RNA tomography and in situ hybridization in the sea star Patiria miniata. The relative spatial expression of these markers in P. miniata ambulacral ectoderm shows similarity with other deuterostomes, with the midline of each ray representing the most anterior territory and the most lateral parts exhibiting a more posterior identity. Strikingly, there is no ectodermal territory in the sea star that expresses the characteristic bilaterian trunk genetic patterning programme. This finding suggests that from the perspective of ectoderm patterning, echinoderms are mostly head-like animals and provides a developmental rationale for the re-evaluation of the events that led to the evolution of the derived adult body plan of echinoderms. RNA tomography and in situ hybridization in echinoderms suggest a new ambulacral-anterior model to relate echinoderm pentaradial symmetry to the ancestral bilateral symmetry.

How do caterpillars acquire chubby legs? Scientists trace the origins to a genetic program associated with crabs
Adult insects, including butterflies and moths, typically have only three pairs of legs. But the existence of extra legs in caterpillars—chubby abdominal appendages also known as "prolegs"—has long posed an evolutionary mystery to biologists. A recent study by researchers from the National University of Singapore (NUS) linked this novel trait to crustaceans.

Black Market Brass - But At What Cost?
neville parkSo I was rereading a cool arachnid evo-devo paper, and I wondered…
Could you make a simple "animal" as a web page, using #CSS and #HTML as #Hox genes and body plan, so that people could tweak things using browser dev tools to hide/duplicate/alter the presentation of elements, the way scientists knock down or upregulate genes to see what it does to the animal?
Evo-devo stuff has always reminded me of using "display: none !important" or "border: 1px solid red" to figure out what CSS rules do. And like CSS Zen Garden—radically altering the look of a page with CSS without touching the HTML.
