Popis: | Without watching evolution in action, it is difficult to imagine how stepwise mutations from a common ancestor can add up to the differences between Escherichia coli and elephants. Field studies, such as those of Darwin's finches in the Galapagos, show that evolution can be observed as it happens in natural populations. But general principles can prove difficult to extrapolate from such studies, in part because evolutionary outcomes have an element of chance and can take a long time to play out. |
