Cogent reasons for doubting Darwin theory:

Hence, there is no argument regarding microevolution. The core of the debate for me, therefore, is the extrapolation of microevolution to macroevolution. Here is what some supporters of Darwinism have written regarding this point in respected journals, and it is apparent that they struggle with the same difficulty.
 •Stern, David L. "Perspective: Evolutionary Developmental Biology and the Problem of Variation," Evolution 2000, 54, 1079-1091. A contribution from the University of Cambridge. "One of the oldest problems in evolutionary biology remains largely unsolved; Historically, the neo-Darwinian synthesizers stressed the predominance of micromutations in evolution, whereas others noted the similarities between some dramatic mutations and evolutionary transitions to argue for macromutationism."
 •Simons, Andrew M. "The Continuity of Microevolution and Macroevolution," Journal of Evolutionary Biology 2002, 15, 688-701. A contribution from Carleton University.'A persistent debate in evolutionary biology is one over the continuity of microevolution and macroevolution — whether macroevolutionary trends are governed by the principles of microevolution.' "-"Some are disconcerted or even angered that I signed a statement back in 2001 along with over 700 other scientists: "We are skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life. Careful examination of the evidence for Darwinian theory should be encouraged." Do not the texts written by the two authors above underscore what I signed, namely, "Careful examination of the evidence for Darwinian theory should be encouraged"? And these "oldest problems in evolutionary biology" lead me and many others to our being "skeptical." It is not a matter of politics. I simply do not understand, chemically, how macroevolution could have happened. Hence, am I not free to join the ranks of the skeptical and to sign such a statement without reprisals from those that disagree with me? Furthermore, when I, a non-conformist, ask proponents for clarification, they get flustered in public and confessional in private wherein they sheepishly confess that they really don't understand either. Well, that is all I am saying: I do not understand. But I am saying it publicly as opposed to privately. Does anyone understand the chemical details behind macroevolution? If so, I would like to sit with that person and be taught, so I invite them to meet with me. Lunch will be my treat. Until then, I will maintain that no chemist understands, hence we are collectively bewildered. And I have not even addressed origin of first life issues. For me, that is even more scientifically mysterious than evolution. Darwin never addressed origin of life, and I can see why he did not; he was far too smart for that. Present day scientists that expose their thoughts on this become ever so timid when they talk with me privately. I simply can not understand the source of their confidence when addressing their positions publicly."
