Did you know that if you compare human, cow and kangaroo DNA, humans and kangaroos are most similar?
Here's a nice chart.
It's wrong, of course. Instead of doing an overview comparison of many genes, or using even more current methods that give even better comparisons, it's based entirely on a single molecule, mitochondrial cytochrome-c. The webpage linked is a discussion on how this works and how to get better results.
As we saw in the comparison of human and kangaroo cytochrome c, a single molecule provides only a narrow window for glimpsing evolutionary relationships.
The technique of DNA-DNA hybridization provides a way of comparing the total genome of two species. Let us examine the procedure as it might be used to assess the evolutionary relationship of species B to species A:

The creationist websites have jumped on this intentional bad example, however, to start making claims in the usual vile way.
When the protein strands of various living things are analysed in a laboratory, results emerge which are totally unexpected from the evolutionists' point of view, and some of which are utterly astounding. For example, the cytochrome-C protein in man differs by 14 amino acids from that in a horse, but by only eight from that in a kangaroo. When the same strand is examined, turtles appear closer to man than to a reptile such as the rattlesnake.

This is the sort of thing that keeps ID from ever getting anywhere near the science class ever again.
The Centre’s Director, Jenny Graves, said, ‘There is great chunks of the human genome which is sitting right there in the kangaroo genome.’ In fact, according to a report in Australia’s national newspaper, the 20,000—25,000 genes in the kangaroo (roughly the same number as in humans) are ‘largely the same’ as in people.1 Graves said elsewhere that ‘a lot of them are in the same order’.

Does anyone here believe that Jennifer Graves actually used the wording attributed to her in those quotation marks?
Another interesting point is that we are obviously seeing the results of a game of telephone. Note what animal does
not occur anywhere in the chart being misrepresented.
