Activator of G-protein signaling C-terminus serves as a variable element to induce asymmetric cell division, facilitating developmental diversity among species.

THE development of Echinoderms from the egg presents one of the most striking of life processes known to us. The changes through which the individual passes are even more remarkable than those ...

“[This was] striking, because we know that the Hox cluster is very conservative in terms of gene order,” said Elise Parey, an evolutionary biologist at University College London and a study coauthor.

New students must be interested in whole organisms and their evolution. Most of my recent experience has involved echinoderms, but I’m not a taxon snob and the occasional mollusk and cnidarian has ...

Fossil echinoderms, including the common Cambrian and Ordovician echinoderms figured here (Fig. 1 from Deline, et al., 2021; request permission to use here) have a rich and diverse fossil record.

The diversity and abundance of echinoderm fossils is reflected in the Museum's large, world-class collection. Fossil echinoderms are numerous, due in part to the fantastic preservation potential of ...

The evolutionary origins of mechanisms that control ... shows that this mechanism is also present in the sea urchin, an echinoderm. Intriguingly, the researchers found that nodal expression ...

He says: "This specimen provides compelling evidence that clonal fragmentation in star-shaped echinoderms has deep evolutionary roots and that it has been linked to life on a host and a six-fold ...
