Brain Regulation Present Even In Spineless Creatures

At a meeting of scientists in Australia, University of Oregon biologist Nathan Tublitz revealed that research on moths, flies and cephalopods showed how brain regulation// is present even in spineless creatures. He also revealed that glutamate and FMRFamide-related peptides are the two brain chemic...

Evolving complexity out of 'junk DNA'

...Sciences, USA, claims to have solved this scientific riddle by analysing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts. Vertebrates - animals such as humans that possess a backbone - are the most anatomically and genetically compl...

Dartmouth researchers find the root of the evolutionary emergence of vertebrates

...aralleled in evolutionary history, says Heimberg. The team studied the genomics of primitive living fishes, such as sharks and lampreys, and their spineless relatives, like the sea squirt. By reconstructing the acquisition history of microRNAs shared between human and mice, the researchers determined that ...

Tiny Tampa Bay fish key to evolution of immune system

...y they have found the "missing link" marking the point in evolution that led to the development of the modern-day human immune system. The inch-long spineless fish, called a lancelet, produces a key immune system protein that is similar to but much hardier than the version found in people. The bay waters are...

Lizard 'third eye' sheds light on evolution of color vision

...as "G-other," which also signals light responses in the light-sensing cells of the scallop and other creatures without a backbone. That Go is found in spineless creatures suggests it is the evolutionarily more ancient light-triggering signal. Although gustducin and Go are different molecules, they are simi...
