The above image is of the 1000 band stage of chromosome 2 of (from left to right): Man, Chimpanzee, Gorilla, and Orangutan.
Take a very close look at the similarities...homology in science lingo...between us and the other great apes. What you are looking at is genetic evidence in favor of evolution, evidence that would be compelling even without the overwhelming supporting evidence from paleantology, embryology, and a dozen other scientific fields. (It is of the type of evidence that gets criminals convicted in our courts.)
Here's the thing...the image was first published as part of a paper in 1982.
In short, creationists, et al, have been closing their eyes and covering their ears for at least 27 years to evidence which they would otherwise readily accept as proof of someone's guilt if presented in a court of law.
And this is just one chromosome. The authors of the paper (reference below) also stated: "Except for differences in nongenic constitutive heterochromatin, chromosomes 6, 13, 19, 21, 22 and X appear to be identical in all four species"
