Evolution doesn't make sense.

Hi amp1022, and welcome to the fray.Others have already pointed out several problems with your posts, however I'd like to add my 2¢s worth. All the evidence available is consilient with the concept of all species evolving from common ancestral populations, with many multitudes of branching events. After branching events have occurred the daughter populations are free to evolve independently, usually taking different paths due to being in different ecologies. Over time this can add up to noticeable differences between living offspring of those daughter populations.I don't expect you to understand or accept this answer (or others given to you) because I don't believe you truly know what you are asking about.Can you define what evolution is?Can you define what speciation is?Can you define what you mean by "a completely different species" andCan you describe how you would expect this to occur through evolution?As an example: is a red fox a completely different species from a wild cat? Can you describe the biological differences that differentiate one species from the other?How would you be able to tell that one is a different species from the other?What is your standard for quantifying differences, your metric for measuring differences? In biological terms a "fully separate species" is an oxymoron. In biological terms speciation has occurred when two or more daughter populations no longer interbreed.A living example of this is the greenish warbler in asia:

The greenish warbler ring species

​

Greenish warblers (Phylloscopus trochiloides) inhabit forests across much of northern and central Asia. In central Siberia, two distinct forms of greenish warbler coexist without interbreeding, and therefore these forms can be considered distinct species.

This shows how mutation and selection in different ecologies can produce sufficient variation for speciation -- the division of a parent population into two or more non-interbreeding daughter populations -- to occur. Eliminate the intermediates and you have two different species. Usually the intermediates are distributed in time rather than in space, and this can be shown with other evidence. Curiously, this has nothing to do with evolution, but it has everything to do with creationist falsehoods\lies. You are mixed up or misinformed, but happily this is curable: you can learn what evolution theory and biological science really says about the diversity of life on earth. But the ones that really insulted you are the ones that told you lies and falsehoods about evolution, perhaps because they didn't think you could handle the truth.Evolution is the change in the frequency distribution and composition of hereditary traits within breeding populations from generation to generation, in response to ecological challenges and opportunities.Speciation is the division of a parent population into two or more reproductively isolated daughter populations that then evolve independently of each other.The Theory of Evolution is that these two processes are sufficient to explain the diversity of life as we know it, from the fossil record, the genetic record, the historical record and the world around us.If you are willing to learn the truth about evolution I can recommend some websites, such as:Evolution 101 - Understanding EvolutionEnjoy.
