Unless you've got something else, maybe?
First off, welome to these threads. I just started myself not too long ago, and I'm already thoroughly addicted!
It really sounds like what your'e asking for is for me to show you a frog morph into a lizard. I can't do that because the differneces between species and thus these "transitions" that everyone keeps talking about are very small. To my understanding, even punctuated equilibrium (http://ucsu.colorado.edu/~lemmon/Research/Paper-EG4-Gradualism.htm) occurs over many generations. These things have been observed in small organisms like bacteria and things with short reproductive cycles, but are usually dismissed as "microevolution" although I don't see the distinction. I CAN show you evolution in action, but you'd either have to accept fruit flies as an example or agree to wait until I find a cure for mortality in order to demonstrate "macroevolution". :)
Also, the distinction between two species is not always clear. The usual rule is that the two groups not be able to produce fertile offspring. Hence Donkeys and Horses are seperate species even though they can reproduce together, because Mules are sterile. Dogs and wolves, on the other hand, are usually classified as differnet species although I THINK they can produce viable offspring. On the other hand, Great Danes and Chihuahuas, while both undeniably dogs, would have a hard time mating naturally. The transitions get blurry. Where do you draw the line? Look at it one way and there are no transitionals, look at it another and EVERYTHING is a transitional. The distinctions we make between species are somewhat arbitrary, thus it gets easy to make unanswerable questions about transitions between species. These types of questions do nothing to disprove evolution, they merely point out difficulties in our categorization techniques.
I have a question that perhaps you can help me with. How did the billions of gallons of oil get to us? I've heard that oil normally originates from animal matter. If so, how did this happen? I personally have a hard time seeing how the oil got here if slowly evolving life has occured in the past.
The commonly accepted theory these days is that oil came from a period far in the past when there was a lot of plant life and other organic material. Very swamplike, to my understanding. This dead material decomposed and was covered up by layers and layers of soil and whatnot. These layers piled up over millions of years, burying the material under miles of rock, yadda, yadda, yadda.
The point is that oil was trapped underground because it is from primitive DEAD life forms from a SPECIFIC PERIOD in Earth's history. Life didn't go away afterwards, it just wasn't in an enviornment conducive to forming oil. That's why we have limited supplies.
