Creation & EvolutionForum for the discussion of this important topic. This forum is open to non-believers. There is a Christians-only forum in the Christians-only section too.
Protista can respond to environmental stimuli via reactions such as Chemotaxis and Phototaxis. These are simple chemical reactions carried out by receptors, and do not constitute thought or emotion. Protozoans do not get sad or happy or angry. Flatworms (Planaria) have a simple nervous system (including a very simple brain) and therefore they are capable of some thought. They does not have emotions, however.
In order to show that these creatures are capable of emotion, they would have to do better than simply respond to environmental stimuli, such as moving toward light or toward a food source. Can you make them angry or happy? Do they wag their flagellum when you scratch them behind the ear?

Lol. I agree. This is these kinds of threads are what happens when people assume that response to stimulus = thinking.

The evidence for the theory of evolution only tips the scale. It is mostly circumstantial and it is NOT enough to get me to believe in it. I would need evidence that is beyond a reasonable doubt, and that kind of evidence is just not there.
Mostly there are other explainations for the data that are more plausible than Darwin's theory.
I won't use the funny response I have for that....
But what good are chemical reactions to cause behaviors when there is nothing to interpret them? If you say these behaviors are only cause by chemical reactions, then what about the behavior of dogs, or that of people? Where does the boundary exist where the blame, so to speak, shifts from chemicals to brains? After all, the brain structure is powered by nothing but chemical interactions. If you say you ascribe emotions to the protista, then do you not also ascribe emotions to dogs, and other animals, and even people? If we ascribe emotions to ourselves, do we really have them, or are they just chemical interactions?
Non sequitor. Notto never said he ascribed emotions to protista, and neither did I. That would be anthropomorphizing: projecting our bias onto the protista. Notice we never got any data of the particular behavior that Custance thought was "emotions".
However, even in humans, emotions are reduced to chemistry. Chemistry in the brain. For instance, the happiness we feel is related to levels of serotonin in the brain.
