> DNA can't change unless a mutation happens
There is also recombination but I will ignore that for now. What's your point with that?
> but we have no proof of these so called missing links
Of course we do have lots of evidence, e.g. fossils: https://en.wikipedia.org/wiki/Archaeopteryx
Also, we have evidence directly in the DNA, in humans e.g. with fused chromosome 2.
> Mutation are 97% of the time harmful to the thing it happens to.
Most BS stat if I have ever seen one, and I have seen 23.54% of all stats. :P
Truth is, most simple mutations are actually neutral.
> Look at Down Syndrome in humans for example.
That's caused by chromosome 21 being there thrice, but again, I don't want to be to nit-picky. Just let me tell you that it's a different kind of error compared to certain base pairs simply changing (what people normally think of), but since such chances also play a role (even more so in plants) I am going to let it slide.
> These creatures would have to live long enough to reproduce and pass on this so called advantage to their offspring and that offspring reproduces and so on.
Yes, so? If there is a selection advantage (can be quite small BTW) then that feature or variation is going to take over the gene pool in the long run, it becomes the new norm.
> Your argument is that these changes add up over time and millions of years later that animal becomes an entirely new animal.
Not necessary millions of years BTW, just enough for speciation to happen (new species is one that can't reliably create viable offspring with another in a very simplified definition for animals). We can observe it with flies in a lab: https://en.wikipedia.org/wiki/Speciation#Artificial_speciation

> Your "sources" are from wikipedia, which is one of the most unreliable sources you could have chose.
Ah, I see, you're an academic and a connoisseur of good sources. Great, I love like-minded people, so then I am going to give you some in your prefered format:

These papers/books should be easily accessible from your university LAN/VPN. What do you think of them?
> You've seen 23.54% of all stats XD
I'm glad you like it. I came up with that number through pretty much the same means as you.
