The comparatively excessive intelligence of octopuses could also be due partly to excessive numbers of microRNAs that would allow them to generate extra varieties of neurons

A research of the exercise of RNA, a kind of genetic materials, within the our bodies of octopuses means that the brains of cephalopods advanced larger complexity in the identical means as vertebrate brains did – by utilizing much more regulatory RNAs known as microRNAs (miRNAs) to regulate gene exercise.

“We present that the main RNA innovation of soft-bodied cephalopods is an enormous growth of the miRNA gene repertoire,” states a research but to be formally peer reviewed, led by Nikolaus Rajewsky on the Max Delbrück …
