Where did the very first singlecelled ameoba come from, it can't have just appeared? Is there anything scientists even guess that's right? We never go to this depth in AS level, but I have always been curious : \
Thanks, maybe.
Amcha.

I meant more of how did it get there, if it was mexico, did it just spontaniously appear, life surely can't come from nothing.

One popular scientific theory is spontaneous aglutination of amino acids and a precursor RNA, not too dissimilar from viruses

Very simple free floating cells appeared first. Over time more complex structures like cilia, flagella, contractile vacuoles and pseudopodia gradually appeared. Some cells that developed pseudopodia eventually gave rise to amoebae. ou are right, it didn't "just appear". The transition from the first cells to amoeba probably took a few million years, and a great many changes.
