Plants eat chemicals to live. Animals eat plants to live. Even carnivores must eat plant-eating animals in order to stay alive. Every animal has to get its veggies somehow.

when a species can only interbreed, its definition as a separate species is unarguable.
The study that you sited seems to suggest that crossing is possible, just not likely. Am I missing something?
Polyploidization has long been recognized as an important force in the diversification of plants. Theoretical models predict that polyploids may be expected to exhibit higher rates of self-fertilization than do closely related diploid species. Wild populations of the neopolyploid Tragopogon mirus (4n) exhibited slightly higher rates of outcrossing than did populations of one of its progenitors, T. dubius (2n). In the current study, outcrossing rates in populations of T. dubius and T. mirus were estimated using artificial arrays constructed to maximize the chances of detecting outcrossing events. The artificial diploid population is more highly outcrossing (t=0.727; family-level estimates range from 0.00 to 1.32) than the tetraploid population (t=0.591; family-level estimates range from 0.00 to 1.14), although the difference between them is not statistically significant. The results of this study, combined with those of the previous work on wild populations, suggest that mating systems in these species vary more among populations than between ploidal levels. This could be because of the relatively recent origins of the tetraploid species; there may have been insufficient time since the formations of the tetraploids for shifts in mating systems to occur.

Lots of history is subjective and to some of those questions we'll never know the answer.
Well, Zagor, we may have to start a new thread when I get the answer - but you have raised an important point, which keeps this thread on tack, namely, that evolution DOES have the answer in relation to how life began

Ian,
Regarding Tacitus, his sources were most often official Roman sources. He did vary from this somewhat and frequently failed to specify his sources, but as I recall there was a problem establishing that this particular bit was not added to his work at a later date. I may be getting this confused with something else. I will be interested to read what you scholarly feelers turn up.

Amoebas are nourished through living on their prey.They eat it by throwing pseudopodia around it, enclosing it in a spherical bubble of water. See: http://tolweb.org/notes/?note_id=51

You See, Ian, That alone is enuff to convince me that we have an Intelligent Creator..Isn't GOD wonderful? He provides for even the lowest forms of creatures.

Ah AuldSoul,, you could have corrected my spelling....LOL...I was up half the morning with my sick dog. That is my excuse. Of course when I am awake, my spelling is not that great.

No, no, TopHat, please don't misunderstand. The spelling was the least disturbing aspect, IMO.
