That answer gets an F because not only did Linnaeus soften his views and no longer accept the fixity of species in his later years, but the question is not in the past tense. The question is in the present tense. Who believes, not believed, in the fixity of species.
Ah, that’s easy. Creationists, right? Wrong again. Go back and do your homework, or if you must, see the next line where the answer is given backwards:

Yes, it is they who believe in the fixity of species. After all, modern evolutionary thought arose in the highly religious culture of seventeenth and eighteenth century western Europe. It was motivated by, and inherits religious ideas from that day. It is, in fact, stuck fast to its centuries-old metaphysical foundation. Far from the cutting-edge science it purports to be, evolution is little more than today’s ossified remains of long-since discarded religious ideas.
For example, as one of the major pillars of evidence for their theory evolutionists cite the adaptation of organisms that we observe in the laboratory and in the field. It is, according to evolutionists, a powerful proof text for evolution. There is a constant stream of evolutionists insisting that such evidence proves evolution to be a fact.
It is as if they are forever stuck in the nineteenth century, replaying Darwin’s marvel at how differing bird populations “undermine the stability of species.” Like Sisyphus forever pushing the rock up the hill, they are forever pushing the absurd idea that resistance to pesticides and antibiotics in plants and microbes, respectively, make evolution the only possibility because as Darwin believed, if God created the species they would be fixed.
As Ernst Mayr pointed out, the doctrine of fixity of species was a key barrier to overcome if the concept of evolution was to flourish:
Darwin called his great work On the Origin of Species, for he was fully conscious of the fact that the change from one species into another was the most fundamental problem of evolution. The fixed, essentialistic species was the fortress to be stormed and destroyed; once this had been accomplished, evolutionary thinking rushed through the breach like a flood through a break in a dike.
And indeed evolutionary thinking eventually did rush in, on the power of metaphysical arguments such as this one. But these powerful religious motivations don’t just go away. Indeed, they provide the justification and motivation in the face of daunting scientific contradictions. And so to this day, evolutionists continually repeat their mantras from centuries past. Here is a typical example of how, today, the religion has become so ingrained in evolutionary thought. Below the video is the text beginning at the 9 second mark.
[0.09] What we study is how viruses and bacteria and other microbes get inside your body to infect them. And what I wanted to talk to you about today was how evolution is involved in that process, and basically why we think evolution is very important to understand.
So, when you get infected by a virus or a bacterium, there is basically a war going on inside your body, where the virus wants to multiply, or the bacteria wants to multiply, and your immune system wants to keep it back down. Now what happens is that, we as humans have evolved over millennia to actually have specific cells and those cells have particular receptors that will get rid of the virus or kill it or sequester it or some way make it so that it can’t infect you and make you sick.
Now the virus then, is evolving inside our bodies to get around that immune system. And if you look at the genes inside viruses, sometimes they steal long stretches of genes from their host, and other times they have mimics of genes in their host. So basically, viruses have this tremendous chance to evolve inside of people, that is their host, so they can get around an immune system.
So a successful virus would be something like influenza virus, that changes every year. So what it does is it mutates. It makes a lot of different forms of itself. Most of these are completely useless—that is they are defective viruses. But out of the millions and millions of viruses that it makes, one or a few of those will be better, and those will go on and multiply and infect other people.
That is evolution at work.
So basically, the viruses make millions of copies of themselves, most of them are worse. They’re making random mutations, random changes. They don’t know beforehand what’s good or what’s bad. The best ones will win out, and those will go on and infect.
In the same way, people have evolved, but over a much slower time scale. So that they made some changes in their immune system, to keep up with particular viruses and other changes that were actually worse. And the changes that were beneficial gradually win out.
So in a nutshell, that’s an example of evolution, at play, in your body, that goes on all the time.
And so I think we need to understand this, because bacteria in particular are able to mutate to get around antibiotics. It’s another example of evolution. We need to understand this, so that we can develop drugs that will actually get around bacteria’s incredible ability to evolve quickly, to get around the drugs we use today. Thank you.
For many this just proves that evolutionists are liars. Or that they are fools.
But when evolutionists such as Professor Bjorkman make these arguments, they are not consciously lying. Here Professor Bjorkman is smart, knowledgeable and honestly speaking her mind.
So how to explain evolutionists, such as Bjorkman, when they present their evolutionary absurdities with all the earnestness of a five-year-old talking about Santa Claus? It isn’t from ignorance or from deceit.
Religion drives science, and it matters.
