To quote evolutionary biologist Leigh Van Valen , quoting Lewis Carroll , " Here , you see , it takes all the running you can do to keep in the same place . The effect on Achatina has been slight because E. rosea prefers to feed on smaller native snails . Carol Spencer , I arrive on my second trip to Myanmar .
