That would be the California two-spot version (the picture to the right), which was the subject of genetic research done by a combined team of scientists from the U.S., Germany, and Japan.
From the looks of it, 'their just-released findings present deep problems for the theory of evolution'.
Well, for starters ...
The researchers’ findings were full of surprises. For example, the scientists documented a total of 33,638 protein-coding genes in the octopus genome, which is about 10,000 more genes than found on the human genome.But that's not the most surprising part:
The analysis also revealed “hundreds of cephalopod-specific genes” that are specific to the octopus family and not found in any other creatures.Not even in the creatures evolutionists have, for decades (at least) considered to be the octopus' ancestors – mollusks. In fact, '[c]ompared to creatures purported to be in its evolutionary lineage, such as mollusks, the octopus is much more complex and intelligent—extraordinarily dissimilar from anything else.'
Here's the problem as I see it:
Genetic changes only come about through mutation.
There are three types of mutation: detrimental, neutral, and beneficial; they're exactly what their names suggest – they cause harm, they do nothing, or they help the organism survive.
Obviously, the 'specific genes' octopi show code for the extraordinary features they show: their camouflage abilities, their eyes, their 'tasting suckers', their nervous system, and so on. These are all beneficial to the organism, hence they must have been beneficial mutations from the basic molluscan genetic plan.
But of the three types of mutation, beneficial ones are the rarest; most common are neutral ones, with negative ones coming in second.
I think you can see the problem. There's really no way for a Darwinian form of evolution – slow and gradual change over time – to account for this.
Which is why this is potentially very bad news for Darwinian evolutionists.
I'm looking forward to seeing how evolutionary biologists handle this.
