Further evidence would suggest that our lunchbox toting amoeba, Dictyostelium discoideum, is not quite so advanced as previously proposed.
It would seem that it does not carry lunch in obedience to the second law of geography field trips at all. Rather, it is a fussy eater and is worried that it might not like the food it finds at journey’s end. To avoid facing “funny foreign muck”, probably covered in the slime mould equivalent of garlic, it takes its own food with it. It is thus rather like the stereotypical British tourist, travelling with a suitcase full of baked beans and PG tips to avoid facing the horrors of the local cuisine.
All a bit disappointing – but it may offer business opportunities for the enterprising single-celled organism who can provide the slime mould analogue of the British pubs on the Costa del Sol.
