My my, it's been a while since my last post here...
I think the others are competent to answer your questions, but I want to answer this one:
quote:
e) The termite or the flagella in its intestines that actually digest the cellulose?
From recent work I've read, microbes (not only flagellates but also bacteria) that digest cellulose are also present at Cryptocercus, an extant cockroach with a feeding habit similar to primitive termites (wood-feeding), and a subsocial lifestyle. Molecular phylogenetic studies suggest that termites evolved from cockroaches, and Cryptocercus is their closest relative. So to answer your question, the flagellates came first, in the guts of ancient wood-feeding cockroaches, then the termites, evolving from those cockroaches.
Btw, welcome, and interesting questions you got there. I hope my explanation makes sense.

Re: co-evolution? are you certain?

Are you saying that there was a time when only wind-pollenated plants existed? Could you help us verify this?
'A time when only wind-pollinated plants exist'? You could get better answers by asking (in accordance to the original question) whether there was a time when no insect-pollinated plants exist.
I assume the great fern & cycad forests of the Carboniferous were not insect-pollinated. Then again, they don't have real flowers either.

quote:
How did the flagella know to do specifically what it does? Wouldn't evolution require lots of trial and error? How would the species survive long enough to learn how to perform the said work?
First, it's 'flagellate' not 'flagella'.
I assume the flagellate just happens to produce enzymes that break down cellulose. A possible scenario is that they were originally found in rotting plant matter, and then got incorporated into the guts of insects that feed on that plant matter.
By the way, somewhere along termite evolution, the flagellates got kicked out. The gut flora of largest family, Termitidae, only consist of bacteria.
I can show you references if you are interested in pursuing this matter further.
As for your other questions I think the others have answered them. Just bear in mind that with a microbe like the flagellate symbiont, their eproductive capacity is enormous so you get lots of trials and lots of chance for errors.

Monkey to man
quote:
All that will change is the variations in height, weight, muscle biuld, etc.. All that comes from the recombination is mutation not new creation. The monkey will stay a monkey and the man will stay a man.
Okay so you begin to show creationist colours. No probs. Let's see, does it take more than variations in height, weight, muscle build to transform a monkey (or a typical ape, if you like) to a man?
Let's see...I'll use the gibbon as my starting point and to change it to a modern man:
-Increase overall body size.
-Increase brain volume
-Shorten body hair
-Make face flatter
-Make canine teeth smaller
-Change proportion of arm & leg length
-Shorter toes, wider feet
-Change lower-body musculature
-And finally, enlarge penis or breasts.
There. From gibbon to human, nothing new needed, just variations. We can bring this to the Human Origins forum if you like.

Re: Monkey to man
{my starting point is the gibbon who don't have a tail to begin with. I know Enuf Already asks for a monkey, but I want to correct her/him on that one}
