IN the case of evolution some people think a fish or a monkey to a human. Do you have evidence of a change of kinds like a fish to a human, or a monkey to a human.
Most but not all. One of the things you were given links to was all about evidence for macroevolution.
Those kinds of changes would overthrow the current understanding of biological evolution. A great oversimplification, but it works more like this:
Monkey->hundreds or thousands of speciation events, almost all of which are not in the lineage of apes->apes->hundreds or thousands of speciation events, almost all of which are not in the lineage of hominids->hominiids->hundreds of speciation events, most of which are not in the lineage of modern humans->humans. Each step taking tens or hundreds of thousands of generations.
The clincher as far as evidence goes (not that what poccaracas offered is insufficiently convincing) is retroviral insertions. When a retrovirus infects a heritable germ line cell, the alterations it makes in its host's DNA can be passed on to subsequent generations. If the change is neutral, it can be carried through speciation events as there is no particular pressure to weed it out. The odds of an identical random retroviral insertion being due to anything but common descent are so remote that two organisms sharing a single such insertion is considered proof beyond a reasonable doubt that they share a common ancestor. Seven retroviral insertions have been found in common between humans and chimps.
