Learning to evolve: With a little help from my ancestors
Learning to fly is easy, if you
are a bird. But why is it that birds learn so easily how to fly" It is well known that birds learn through practice, and that they gradually refine their innate ability into a finely tuned skill. According to a new theory by Dr Stone of Sheffield Uni...

cant get a really tight off state. Even when genetic switches are turned off, a trickle of the protein that is meant to be repressed still gets made. Some genetic switches get around this by entirely snipping out a gene to stop production of a spec...
