Is Evolution a science or a faith?

[Natachan]

Mutations rarely occur natural world and when they occur, 100% of them are injurious.

Do you have any evidence for this claim? I believe it is false.

Yup, it's false. In every embryo there are hundreds of mutations, most of which are neutral or have no effect. Some of these result in slight changes in morphology and can be passed down in later generations.

Neutral mutations only give variations in the same specie if not the same property.

Just a moment ago you said that 100% of mutations were injurious. You can't even keep your own lies straight. This, too, is false.

Indeed. In fact beneficial and deleterious mutations occur at about equal rates with deleterious being only slightly more common. But as stated above most mutations are neutral in effect and are not selected for or against.
