Hardcore brexiteers read Iains latest link and take note...

" In mammals, one of the most dramatic responses to an insular environment is a change in body size. First noted in 1964, this pattern of body size changes in insular mammals became known as the "Island Rule". Although it is not a true rule, it describes a trend in which small mammals increase in size (insular gigantism), whereas large mammals will become smaller (insular dwarfism)....
Island species respond to this ecological release by losing adaptations that were necessary on the mainland, and evolve new ones by adaption to their new island home, which can result in a cascade of changes in behaviour, reproduction, population dynamics and anatomy."

Too many indigenous British are already pudgy past-faced stunty specimens at best...
We need the healthy genes of much more attractive foreign races to prevent us devolving even further down the uglyometric scale... 😜
