I read this thread from start to finish, to try to understand it. There is some fascinating biology referred to above. A lot of it I never knew about before. Anyway, here are some questions for Vidqun, in relation to his/her lengthy last post:
1. Complexity: Isn't your argument is like saying:
"I don't know whether the first car that went past my house this morning was a red car, a blue car, or what colour. There are so many potential colours. Until we can prove what colour it was, we have to assume NO car went past my house."
2. Amoebal Immunity: Your 4th sentence seems to contradict your first sentence. Also, how does the unidentified article extract support your point?
3. Human cancer cells: What relevance is the name you choose to give to a human cancer cell? If we call a human cancer cell a "banana", will it become edibile? Also, what is the relevance of HPV causing cancer, to the overall debate. (Viruses aren't prokaryotes.)
4. Natural Selection: You have quoted part of the 7th last para of a lengthy article written in 2004 titled "Gene switching in Amoeba proteus caused by endosymbiotic bacteria". Yes, the new life form wasn't a superbug ready to ravage the planet. The xD amoebae only out-populated its relatives when maintained in the same laboratory conditions within which it evolved.
5. Super improved organisms: Why should they be? See 4 above.
6. Unclear evolutionary history: See the car colour analogy in 1 above.
7. Why did chloroplasts not find their way into the animal and human genome? I don't know but my guess would be that the first animals lived in the sea where there would not have been any use for chloroplasts, and by the time they walked on land, it was easier for them to eat vegetation and other animals? Maybe photosynthesis doesn't provide enough energy for an animal to walk around. Lack of chloroplasts in animals seems more of an argument FOR evolution, then against it, to me.
8. "Again, the fossil record is full of gaps and do not support symbiogenesis as the principal mechanism of developing life forms." Yet the section you quote (wherever it is from) seems to suggest the opposite.
9. Unnatural Gene Manipulation by Researchers: your supposed point seems to contradict the quote supporting your point 5.
