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 ...

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 ...

Caption Fossil echinoderms—including the edrioasteroid here (Carneyella pilea, Corryville Formation, Dent, Ohio, CMCIP 26324 specimen 12.8 mm wide) attached to a crinoid stem in life position ...

Future studies, the team says, will further illuminate “the evolution and molecular mechanisms of the echinoderm MCT.” This deeper understanding could be the catalyst for future research break ...

DR. HUBERT LYMAN CLARK‘S large work, "Echinoderms from Australia", was reviewed in Nature of September 24, 1938. That review and the obituary notice of Dr. Clark in Nature of September 20 ...

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 ...

These creatures, along with other echinoderms such as sea urchins ... creatures infinitely more puzzling is the fact that their evolutionary records suggest they evolved from ancestors with ...
