The draft of the human genome project reveals an unexpected distribution of Alu interspersed repetitive sequences [1]. This has been interpreted as evidence that Alu sequences 'may benefit their human hosts' [1] and that they 'have a positive function' [2]. The implication is that the majority of Alu sequences increase the Darwinian fitness of their(More)

They are typically caused by an environmental change such as unusual climatic conditions, or, increasingly, the actions of humans, as in over-hunting and habitat destruction.
