What's most surprising, researchers say, is how closely the amphibian's genome resembles that of the mouse and the human, with large swathes of frog DNA on several chromosomes having genes arranged in the same order as in these mammals. …
"There are megabases of sequence where gene order has changed very little since the last common ancestor" of amphibians, birds and mammals about 360 million years ago, says bioinformaticist Uffe Hellsten at the US Department of Energy's Joint Genome Institute in Walnut Creek, California, a co-author on the study. …
Such conservation has important evolutionary implications. "By comparing the genomes of these different animals, you can really tell what the ancestral complement of genes may have been," says Richard Harland, a molecular and developmental biologist at the University of California, Berkeley, who also took part in the study.
In addition, says Harland, it belies the view that genomes as a rule evolve quickly. "I think the old expectation was that there was a lot of chromosome rearrangement, but I think increasingly we are finding that chromosomal translocations are pretty rare."
So much for another “old expectation” based on evolutionary thinking. After all, it is not as though evolutionists had no reason for their prediction. Other vertebrate genomes are known to vary substantially more than this. But now we must believe in remarkable genetic conservation over 360 million years.
This of course will not be the last surprise. You can bet new genomes will be found that have more differences but yet have far less time to evolve those differences. This will leave evolutionists saying remarkable genetic similarity is conserved over hundreds of millions of years yet is lost over tens of millions of years. It all depends on which species you examine.
Nothing in biology makes sense in the light of evolution.
