This is more evidence showing that junk DNA is a failing notion.
"Scientists also sequenced random chunks of the salamander genome. At about 30 billion bases and 10 times the size of the human genome, it is one of the largest among vertebrates. Most scientists expected that the extra DNA would be made up of junk DNA, long stretches of bases between genes. But initial findings were surprising. "Genes are on average 5 to 10 times larger than those in other vertebrates," says Voss. "The region of the genome containing genes is estimated to be more than two gigabases, which is as big as some entire genomes."
