Amoeba can move freely. Would I be correct in assuming that this movement is not completely random? Would it be correct to assume that an amoeba can seek out food and can attempt to avoid danger?
If this assumption is correct, would it be reasonable to assume that the amoeba has states which are roughly equivalent to being in pain? If this is not the case, what is it that motivates the amoeba to pursue food and avoid danger? Or is it believed to be instinctual -- that is, fully scripted without a need to presuppose a pain state?
Update from a search on the web:
I did find this article which suggests to me that amoebas might also show avoidance behavior.
