I'm glad you recognize that "some" evolution has been observed. The evidence is strong that the creation of different species has been an evolutionary process.
Sure there are many missing links in the fossil record. That is the nature of fossilization. Sure, one can't demonstrate a continous lineage from single cell organism to humans.
But as you admit there is a lot of evidence that different species have involved.
The above is a very simple scientific summary of evolution. It is what should be taught in science class. It is what was taught to me in college as a GeoChem major.
As I look through my old Geology, Paleontology, Stratigraphy books that I saved from college, I notice that nowhere in these books does it say that man evolved from apes.
Particularly in my "Evolution of the Earth" science book I look for any such statement of fact and I don't see it. When this books mentions Darwin, it doesn't cover Darwin's postulation about apes and man. It does mention natural selection, the fossil record and the specifics of cell mutations.
This is science. ID is not science.
