The number of chromosomal rearrangements, as well as other types of genome changes, was found to be much lower in the primate lineage, indicating that evolutionary change has occurred at a faster rate in rodents than in primates. The new analysis also underscores the fact that while rats and mice look very similar to the human eye, there are significant genomic differences between the two types of rodents.

It is similarly difficult to identify regulatory regions within DNA - the "switches" that turn gene expression on or off, up or down - as they exist only as poorly defined "consensus" sequences. On average, the protein-coding regions of the mouse and human genomes are 85 percent identical; ...

About 90 percent of its estimated 25,000 to 30,000 genes have counterparts in humans and mice. Gary Churchill, a senior scientist at the Jackson Laboratory in Bar Harbor, Maine, said having the genetic sequences of two closely related mammals ...

(For some otherwise rational people, this is a genuine concern.) They are not indestructible, and there are not as many of them as we think. The one-rat-per-human in New York City estimate is pure fiction.

So I think for many reasons it's ... "The Earth After Us." And in it, he tosses out this idea that the animals best suited to take over after we're gone are rats....

In fact, rats rarely bite humans and only do so when they are afraid, hurt or unwell and feel they have no other option. Thankfully, rats tend to be less nervous than other small pets, such as hamsters and mice.
