[0] "They remember, anticipate and decide." [0] They practice primitive agriculture: "they carry, seed and prudently harvest their food" (though no cultivation - what dummies!). [1] And here's the kicker: "P. polycephalum ... spends most of its life as a single cell containing millions of nuclei, small sacs of DNA, enzymes and proteins." [0], but "When prey bacteria become scarce, Dictyostelium discoideum amoebae aggregate by the tens of thousands and produce a multicellular…
