If nature is "clever" enough to evolve radar then radar jamming wouldnt be far behind.
Indeed a human parody is in order here (stolen from a brit comedian). In 1909 Louis Bleriot became the first man to fly from France to the UK across the English channel. In the same year the first serious anti-aircraft gun was created.
Some artistic license there but it highlights the point :)
Nature is the best hacker of all.
