Nothing in your statement suggests evolution is wrong, just not entirely explained. The power of meta rules, and fractal like compact instructions is amazing. A few simple rules and some recursion can generate some exquisitely complex features. Computer graphic generated trees, clouds and other features with fractals demonstrates the concept. A lot of the early chemical warfare among bacteria, viruses, and monocelluar organisms, I believe laid the ground work for some pretty well optimized encoded rules for the evolution process itself. Those lifeforms were incredibly numerous and went through untold generations in the early days of the process.

Evolution really isn't in doubt. Things naturally evolve. Currently we are force evolving human beings and AI. And over the course of another million years, we can't imagine what we will evolve too, or what other lifeforms we might spawn. Our projected evolution demonstrates how the process can be quite non-linear.

As the DNA profiling of all mammals continues along with those that are extinct, I think it will be more clear how the process proceeded. Often it is surprising how little difference in DNA can achieve large differences in species. I don't think it is a secret that all the ways that natural selection occurs and all the forces that impact alteration of genes have not yet been uncovered. I think animals like giraffes are nut tough to explain. Species that find niches (like having a reach for eating vegetation that other animals can't reach), will go through a rapid accleration of the selecting for that trait. I believe this is why in the fossil record it is hard to find "missing links." Once you get a good feature, natural selection will rapidly and significanty alter the organism by maxing out(optimizing) the feature.

I think it is relatively recently that it was discovered that environmental factors do affect what genes are turned on and can directly impact next generation offspring. So there is some level of environmentally directed evolution.

You are right that the process is so amazing and (seemingly) complex, it is understandable why some people won't/can't accept it.
