The major claims of evolution are the creation of novel cell types, tissue types, organs, and body plans. These are required to get from bacteria to baboons. No evolution of these by any means has been observed. They simply appear fully formed in the fossil record and can be observed fully formed in living things today. Given the definition of a theory as a well tested explanation there is no theory of evolution but rather only hypotheses of evolution. Until a hypothetical mechanism is observed doing that which it is claimed it can do these mechanisms remain hypothetical. Honest scientists admit this. For example:
“The history of organic life is undemonstrable; we cannot prove a whole lot in evolutionary biology, and our findings will always be hypothesis. There is one true evolutionary history of life, and whether we will actually ever know it is not likely. Most importantly, we have to think about questioning underlying assumptions, whether we are dealing with molecules or anything else.†Jeffrey H. Schwartz, Professor of Biological Anthropology, University of Pittsburgh, February 9, 2007, Source
On the other hand, dishonest scientists applaud suing a public school for adding the following disclaimer to a biology textbook
This textbook contains material on evolution. Evolution is a theory, not a fact, regarding the origin of living things. This material should be approached with an open mind, studied carefully, and critically considered.
The school was even kind enough to call it a theory instead of an hypothesis. Amazing, isn’t it?
