Evolution in real time


The Harvard Gazette reports on a scientist’s claims about the time travel properties of his lab freezer. It allows him to put super old generations of bacteria side-by-side their distant kin to study evolutionary leaps. This work is fascinating, but also raises questions about what kind of time is being experienced by these microbes (i.e., would the evolutionary story play out differently beyond the controlled space of the lab?).
