Genomes look very similar. I think this is more evidence that genomes represent a basic pattern in programming and that other layers of code create the differences:-http://www.reuters.com/article/2008/11/18/us-australia-kangaroos-idUSTRE4AH1P020081118- "(Reuters) - Australia's kangaroos are genetically similar to humans and may have first evolved in China, Australian researchers said Tuesday.-"Scientists said they had for the first time mapped the genetic code of the Australian marsupials and found much of it was similar to the genome for humans, the government-backed Center of Excellence for Kangaroo Genomics said.-"There are a few differences, we have a few more of this, a few less of that, but they are the same genes and a lot of them are in the same order," center Director Jenny Graves told reporters in Melbourne.-"We thought they'd be completely scrambled, but they're not. There is great chunks of the human genome which is sitting right there in the kangaroo genome," Graves said, according to AAP."
