Hello there shadow,
So you want me to criticize evolution?
...Ok evolution I stab at thee.
Abiogenesis - Nobody knows exactly how it works yet. There are strong conjectures emerging and there are also busy little bees in laboratories building self replicating molecules, but nothing remotely close to a complete satisfactory explanation.
The common ancestor - Turns out these self replicating molecules were shooting their material at each other in all sorts of novel ways, so the common ancestor is probably not a single individual but rather a gooey mush of ancestors.
The fossil record - It will always remain incomplete no matter how many intermediaries are found.
AND here's the current dirty secret: Aquatic ape theory. Why are humans relatively hairless? Why do we need iodine in our diets in rather elevated quantities compared to other apes? Why can humans get sickeningly fat like sea cows? Have you ever seen an obese chimpanzee? Why are we bipedal when other apes on the savanna plains still use all fours (well mostly). There are many other facts which don't add up currently.
