echinoderms, and early vertebrates. This was a period of intense evolutionary experimentation. Strange and wacky creatures struggled to survive, and competition was fierce. As the first animals ...

Srivastava noted that studying this rearrangement can provide important insights about the role of this gene cluster in echinoderms. “Hox genes seem to have a lot of constraint across evolution,” said ...

The findings were made by researchers at the Centre for Genomic Regulation (CRG) in Barcelona and are published today in the journal Nature Ecology and Evolution. Remarkably, the study found that ...

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.

Investigations of immune recognition in nonmammalian species provide new insights into the evolution of immunity ... one branch includes echinoderms such as sea urchins and the other includes ...

Fossil echinoderms—including the multiple, crowded edrioasteroids here (Euryeschatia reboulorum, Tiouririne Formation, Katian Anti-Atlas Range, Morocco, NHMUK EE 14803 specimen 10.4 cm long ...

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 ...

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 ...
