And there's one thing missing. The genetic code has changed drastically too. We have DNA from the ancient corn, so it's possible to compare.
I had an image of that comparison too somewhere, but can't find it right now.

Jeez guys, don't be so corny!
Well unless you are descendants of corn, that is
Ah, shucks

I don't know. What does it say?
That it was unintelligent to begin with. At least by human standards and thats not saying much.

And we redesigned it how?
By letting nature mutate the DNA, and us selecting the ones that fit what we wanted, and over time, the pressure of our selection of small changes became large chances, resulting in a grass becoming a large edible vegetable with completely new DNA.
Let's see how that applies to evolution? Evolution dictates that mutation in combination with selection produces new varieties over time. In other words, that's exactly what happened here.
Evolution is minus the intelligent guidance. Evolutions are just winging it and they close their eyes when they shoot.

Here's what 9,000 years of breeding has done to corn, (and watermelon and peaches in the link)

But for real though, that's actually pretty cool.

Not necessarily.
The choices made by consumers aren't always intelligent or intended.
Samurai Crabs come to mind. Also, the corn was most likely selected for by humans based on taste and texture reasons.
Besides, what's selected for isn't really a "guidance" but rather a sieve.
In the theory of evolution, there isn't really a differentiation between artificial selection and natural selection. Both are equally valid parts of the theory.
There are other forms of selection, sexual selection for instance. Also, selection isn't a single dimension, but there's always things that are selected for and against simultaneous.

I wanna try that rangpur and tayberry. I wonder if the tayberry taste like popping both a blackberry and raspberry in your mouth at the same time? And a cross between a lemon and a mandarin orange sounds like it might be really tasty.
Is this really natural evolution being discussed with corn or the power of selective breeding?
Just look at what selective breeding has done to the diversity of dog types. You could probably make breeds of humans that were tall/short, passive/aggressive, smart/dumb, etc.. Weird to imagine. Eugenics wants to do that by breeding in good qualities and breeding out bad qualities.
Just think, we may look like the corn on the left of the OP picture and are descendants in 50,000 years would look like the corn on the right.

It demonstrates that enormous changes can occur in only 10,000 years. The changes occurred through breeding and possibly through mutations. The same amount of change might be possible through breeding animals. If for 10,000 years we breed elephants, then we might be able to improve the intelligence of future elephants. We might also make them smaller or faster or darker or more pleasant. We might breed them into housepets and have very tiny stupid elephants. We might breed racing elephants or elephants that can carry a tune. That breeding can totally change one creature into another is what this corn demonstrates.George Ananda said:

I think they actually have compared the DNA (or RNA) from the ancient maize with modern, and found differences, i.e. different genetic material that could only have been introduced by mutation (or perhaps sideway bacterial infection or similar). And those mutated changes in the DNA is responsible for the morphological changes. That's how genetics works after all. Our genes do control largely how we look.
Put it this way. If you take a seed from the modern corn and plant it, you will get a plant that is very much the same as the original (it can be slightly different because of mutations or expressions, but to 99.9999..%, it's the same looking plant). If you take a seed from the ancient maize and plant it, you'll get a plant looking like the ancient plant. How do they know to grow to become the same as their "parents"? Through the genetic code, mostly. A plant will grow to become something very similar, almost identical, to its parent plant because the genetic code is there. So we know that the ancient maize and the modern maize must have different genetic code. If not, then we have to figure out how phenotype is really transferred if not by DNA.
