According to a new research paper published by PLoS Biology, mice and humans differ in one out five genes, much more than believed before. This is particularly important because mice are used to research human illnesses and medicines.
One thing that called my attention is that mice appear to have evolved quite faster than us, what I guess is because the generation lapse of most rodents is much shorter than the ones of primates. Whatever the reason, they have accumulated double gene duplications than us in the time since our evolutionary divergence, some 90 million years ago (apparently).
