    Just think…to an Amoeba, your body is its Universe!.
    But seriously, when you see the organisation, synchronisation and structural changes that a single cell organism can and does go through over relatively short spans of time, it is very obvious we evolved and this god created us bunk is just the ramblings of mad men!

    Slime molds seem like sort of outsiders that are trying to reinvent some of the stuff that multi-cellular things usually do. And do it so well – long time ago people just assumed that they're some another weird kind of fungi
