Lots of small changes do not equal a huge leap into another brand new species. This has NEVER been observed and never will be because it is impossible.
Sorry, this has been observed in ring species (among other places). A ring species is a group or related organisms, each slightly differing from the next, arranged in a ring around some geographic feature.
Each group can interbreed with the adjacent groups, but the species at the endpoints of the ring can't interbreed with one another--the definition of a species. These ring species have the added advantage of preserving all of the intermediate species (transitionals) intact for study.
If we can observe speciation (macro-evolution) in contemporaneous populations, why do you assume it is impossible given millions of years?
If you think massive new information to the Genome is not required to produce a new feature in an organizm I highly recommend you head down to the libraries you keep refering to
