Bucane, here is an article which may be of interest to you. Whilst the genetics may be a bit daunting, it is worth the effort. The most interesting case relates to the human GLO pseudogene.
Humans share with other primates the inability to synthesise ascorbic acid. Therefore it has to be obtained through dietary intake (vitamin C). However all other mammals (except the guinea pig) can synthesise ascorbic acid. Primates have a non-functional version of the gene encoding the enzyme protein L-gulono-gamma-lactone odixase (GLO). In 1999 Ohta and Nishikimi found that humans, chimpanzee, macaque and orangutan share a common crippling single nucleotide deletion that causes a triple reading shift.

The simplest explanation is that the primates are all derived from a common ancestor which had the particular mutation which rendered the GLO gene inoperative. Alternative "explanations" such as special creation of humans and intelligent design do not offer a satisfactory explanation for the data.
I note that you have not given the usual creationist strawman version of evolution saying that we evolved from chimpanzees or gorillas. That bodes well.
