Why conservationists should heed Pokémon
Could you tell a Pikachu from a Pidgeotto or a Jigglypuff? The average eight-year old can identify 80 per cent of all Pokémon characters – but is much less expert at identifying real wildlife species. A team of Cambridge University scientists has, found that children were much less... view more (2002-03-27)
