Scientists conclude Octopus DNA is out of THIS world

A new study has led researchers to conclude that Octopuses (NOT Octopi) have Alien DNA. Their genome shows a never-before-seen level of complexity with a staggering 33,000 protein-coding genes identified, more than in a human being.
The oceans of our planet hide countless mysteries that could
perhaps help answer numerous mysteries of life itself. During the last couple
of decades, marine biologists have made small but steady progress towards a
deeper understanding of nature and life.
A group of researchers decided to do some science and chose
the cephalopods in order to try and break down their DNA code, hoping to
understand them better.
The octopus, squid, and cuttlefish are integrated into the
coleoid sub-class of the molluscs. They have an evolutionary history that goes
back over 500 million years, a period long before plants moved onto land. These
creatures inhabit nearly every single ocean at almost any depth.
They are mainly characterized by a vast range of incredible
morphological wrinkles: camera-like eyes, really flexible bodies, and
‘sophisticated’ chameleonic response. All of this is ruled by the larger
nervous system found among invertebrates, which makes these beings the rulers
of the oceans.
They possess highly developed brains and are considered as
the most intelligent invertebrate demonstrating elaborate problem-solving
behaviours. And ss if it wasn’t freaky enough for octopuses to open up jam
jars, scientists have just concluded that these aquatic creatures are even more
mysterious.
Thanks to the first-ever full genome sequence, researchers
have found that octopuses (NOT Octopi) are in fact entirely different from any
other animals on our planet. Their genome shows a never-before-seen level of
complexity with a staggering 33,000 protein-coding genes identified, more than
in a human being.
US researcher Dr. Clifton Ragsdale, from the University of
Chicago, said: The octopus appears to be utterly different from all other
animals, even other molluscs, with its eight prehensile arms, its large brain,
and its clever problem-solving abilities.
“The late British
zoologist Martin Wells said the octopus is an alien. In this sense, then, our
paper describes the first sequenced genome from an alien.”
One of the mains reasons why researchers decided to
investigate the molecular basis of cephalopod brain, was its ability to adapt
instantly its neural network properties which result in a great impact in
memory and learning capacity. These specific capabilities offer an explanation
within the genome that incorporates biological mechanisms that allow tissues to
rapidly change proteins in order to alter their function.
According to researchers from the University of Chicago, the
octopus genome is enriched in transposons, commonly referred to as “jumping
genes,” which can rearrange themselves on the genome. Even though their role in
octopuses is unclear, researchers found elevated transposon expression in
neural tissues. Transposons are known to have the ability to affect the
regulation of gene expression and are believed to play major roles in shaping
genome structure.
“With a few notable
exceptions, the octopus basically has a typical invertebrate genome that’s just
been completely rearranged, like it’s been put into a blender and mixed,” said
Caroline Albertin, co-lead author and graduate student in Organismal Biology
and Anatomy at the University of Chicago. “This leads to genes being placed in
new genomic environments with different regulatory elements, and was an
entirely unexpected finding.”
Octopuses have an alien genetic baggage. The scientific
report mainly concluded that Octopuses share ‘Alien’ genes.This has been a
ground shaking claim in the scientific community which caused an upheaval among
marine biologists who seemed to be shocked and intrigued at the same time.
It turns out that apparently, we’ve had under our nose a
link to humanity’s mysteries, and many of life’s greatest enigmas can be solved
if we only decide to pay more attention to our ocean and everything inside of
it.
The findings are published in the Journal Nature.
