A new DNA study has revealed that octopuses are so weird that
they may be categorized as ‘aliens’.
Researchers from the University of California conducted
their study on a two-spot California octopus, discovering the probable reasons
behind octopuses’ evolved central nervous systems and their fantastic ability
to deceptively camouflage.
The late British zoologist Martin Wells was the first to
describe the sea-inhabiting creatures as “aliens,” primarily because octopuses’
protein-coding structures are much more evolved than even humans.
But now the first full cephalopod genome sequence shows that
octopuses (not to be confused with octopi) are extremely different from any
other animal – with their genome showing a staggering level of complexity. The
new DNA study, published in the scientific journal Nature, has
identified the presence of more than 33,000 protein-coding genes in octopuses,
significantly more than humans.
And that is not all. According to Irish Examiner,
scientists also confirmed that the DNA of an octopus is highly rearranged– like cards shuffled
and reshuffled in a pack – containing several “jumping genes” that can leap
around the genome.
Humans have often found themselves astounded by octopuses’
abilities to carry out functions which would be deemed impossible for most
animals – now we know why it is so easy for an octopus to open a jar of jam!
In fact, Inquisitr recently reported a case where an octopus broke out of an aquarium in Seattle, much to the
horror and surprise a number of visitors present there.
But escaping out of a tank or a jar is the very least we
could expect from these highly evolved beings. American oceanographer David
Gallo has extensively documented the octopuses’ abilities to camouflage
themselves when under threat. Basically shapeshifting creatures, octopuses can
assume the texture and color of their surroundings to ward off underwater
predators.
In this amazing video below, you can see an octopus
camouflaging itself by almost ‘turning’ itself into coral algae
“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. Martin Wells said the octopus is an alien. In this sense, then, our paper describes the first sequenced genome from an alien.”
So next time if you see an octopus conducting a strange and
unbelievable feat, relax. Just know that octopuses are way ahead of us, and in
that regard, they are our only home-grown “aliens.”
Scientists (yep, actual scientists) made this tongue-in-cheek revelation after studying their DNA and deciding that it was so complex it almost couldn’t have originated from Earth.
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.’
Alas, some spoil-sport has done away with the theory using something called ‘logic’.
