Man's idea of alien creatures has always sprung from outer space.
Books, movies and television shows have been depicting aliens as
creatures not of this world.
However, an international team of researchers recently labelled a
creature common to human beings and definitely from Earth as being an
"alien." This is the octopus.
Scientists from the US, Germany, and Japan made this
description after completing a groundbreaking, in-depth analysis of the
genetic makeup of the eight-armed creature, particularly the California
two-spot octopus.
The research findings, recently published in the scientific journal
Nature, bolstered observations of the octopus being a very unusual
creature.
For instance, the researchers documented a total of 33,638
protein-coding genes in the octopus genome—which is 10,000 more than the
genes found on the human genome.
"The octopus appears so utterly different from all other animals,
even ones it's related to, that the British zoologist Martin Wells
famously called it an alien. In that sense, you could say our paper
describes the first sequenced genome from an alien," neurobiologist
Clifton Ragsdale, the study's co-leader, explained.
The team of scientists also discovered hundreds of
"cephalopod-specific" genes that can only be found in the octopus
family. For instance, a particular gene gives the octopus a "remarkable
ability to taste with its suckers."
Aside from this, the octopus was also found to be more complex and
intelligent compared to other mollusks. In particular, the nervous
system of the octopus was described as "vastly modified in size and
organisation relative to other molluscs."
"Soft-bodied cephalopods such as the octopus show remarkable
morphological departures from the basic molluscan body plan, including
dexterous arms lined with hundreds of suckers that function as
specialized tactile and chemosensory organs, and an elaborate
chromatophore system under direct neural control that enables rapid
changes in appearance," the research stated.
The vast dissimilarity between the octopus and other animals has
prompted some scientists to describe the creature as "the pinnacle of an
evolutionary track alternate from man."
In an article published on Friday in the non-profit Discovery
Institute, scientists said evolutionists are struggling to make sense of
the octopus.
"How could so many unique genes arise by blind neo-Darwinian
processes?" the article asks. "It's unsatisfying to hear scientists
assume they 'developed' somehow."
The Discovery Institute said highly complex creatures like the
octopus do not support evolution and point instead to something else:
design.
