Therefore, in order to test evolutionary theories, we need to use animals that reproduce quickly. The hypothesis would be that genetic mutations that benefit a species (i.e., result in greater reproductive success) are more likely than are other mutations to be passed on to offspring, resulting in a long-term, phenotypic change in the species. The null hypothesis would be that genetic mutations that benefit the species are not more likely than are other mutations to be passed on to offspring, and, therefore, do not result in a long-term, phenotypic change in the species. There are any number of empirical tests of these hypotheses. Some have involved viruses. In fact, a great example is the fact that the influenza virus mutates constantly.
All of this is what is described here as microevolution. Sure small changes can be generated in our lifetimes, but where and how did life originate ? What about the large differences between different phyla ? How did they come about ?
First, I'd like to note that I'm not here to advocate other theories. I feel as though every time I ask a question about ID, all I get are attacks against other, extant theories. This is what I was referring to when I wrote that many ID proponents here have so far substantiated their beliefs with false dichotomies (i.e., if they're wrong, we must be right). Even if you do shoot down evolutionary theory
entirely, it won't add
one iota of support to ID theory. Just because they're wrong (which I've yet to see) doesn't mean ID is right... or even
supported.
Nonetheless, I'll respond somewhat to your questions, though I don't see how this is progressing my education in ID.
Question 1: Where and how did life originate?
Everyone here seems adamant that intelligent design and creationism are distinct, but questions such as this blur that distinction. Ark-Magic directed me to
http://www.reasons.org, where I found the following distinction between creationism and ID:
"Creationism focuses on the cause and beginning of the universe. Intelligent design focuses on arrangements of preexisting materials that point to a designing intelligence."
Thus, your first question relates to creationism, not ID theory. In any case, there are multiple theories on the formation of life. I won't discuss alternate theories here, because they would compete with creationism theory, and I want to learn about ID, not creationism. If anyone would like to learn about such theories, try this site for a start:

Question 2 (&3): What about the large differences between phyla? How did they come about?
What you're curious about is called "speciation". Go here to understand those theories:

Again, I don't want to review any such theories, because that's not what this site is about. I'm not here to advocate alternate theories and I don't understand how attacking them provides any support whatsoever for ID. If nothing else, these other theories at least help to show that other scientific theories are testable and objective. I'm sure ID is as well. All I want to hear from someone is the objective, empirically testable, falsifiable hypothesis underlying ID. I think that's what's really missing for me.
I'm not trying to be difficult... really. I
want to test the theory of ID or at least be able to design a study that would test that theory. All I can find online are
theoretical articles supporting ID.
None of them is
empirical. ID advocates would have a drastically better scientific base of operations if they could produce some
empirical research. I want to do that research and advocates here should certainly want their opinions vindicated. Many ID advocates seem to feel that the scientific community is excluding ID out of hand, without any consideration whatsoever. From what I've read, it just seems to me that skeptics are frustrated because ID proponents haven't provided a way to test their hypotheses. That's something that's required of
any scientific theory.
