 Another very interesting area of research that may lead to important medical benefits in the future is studying comb jellies– a complex organism that is now viewed as coming very early on the evolutionary ladder.

1. "Moroz Lab Research on the Comb Jelly in Nature"

'Comb jellies – a seemingly simple form of marine life — took a radically different path to neural complexity than the rest of the animal kingdom, a finding that could have implications for synthetic and regenerative medicine, new University of Florida research shows.

In an article being published May 21 in the journal Nature, researcher Leonid Moroz and his team decode the genomic blueprints for 10 ctenophore – or comb jelly – species, an analysis that suggests these beautiful sea creatures form the first branch on the animal kingdom's Tree of Life. In a remarkable evolutionary twist, ctenophores independently developed complex organs, neurons, muscles and behaviors that are far more sophisticated than sponges, which previously were viewed as the earliest lineage and do not have neuro-muscular systems.

The findings would reclassify comb jellies, reshaping two centuries of zoological thought, and imply that there are many ways to "make an animal" with neural and muscular systems, Moroz said.'

"What if we could not only slow the progression of Parkinson's or memory loss in aging, but reverse it?" Moroz asks. "Ctenophores show us that there is more than one design for a complex nervous and muscular organization.

"Nature is much more innovative than we thought."
