"How did complex life evolve? The answer could be inside out" Topic

"A new idea about the origin of complex life turns current theories inside out. Scientists explain their 'inside-out' theory of how eukaryotic cells, which all multicellular life -- including us -- are formed of, might have evolved…"

Dear Armand

OK, I got it. It's an interesting theory. But my question is that a bacterium can be trapped by the blebs- ok. In the growth of the "blebs" thy eventually ngulf or grow around the bacterium. OK. Maybe it is possible for both to survive that way. But so far they still seem to be separate organisms, one trapped inside the other. How does the trapped one get energy or food and how does the outer one not digest the inner one. I understand that the author is saying that with the fusing of the blebs there is now an inner membrane of the bacteria, and surrounding it the membrane of the original Arachoia, but… how do they become one organism? Or do they remain separate and excretions or the products of waste from one the food of the other, or the carrier of stimuli and message to various parts of the now more complex cell.

How then does mitosis work? That is both cells splitting and forming two new organisms.

Like evolution on a much larger and more complex level, which produces species and interspecies and extinctions continuously, I think the answer to "how did it all start up" is probably that many different proto cell types "went at it" and only the successful ones endured. Our planet has massive overlap of shared cellular traits in all living things. But like something as recent as Neanderthal going extinct, isn't it likely that a relatively recent extinction of cell generation types has occurred? Why look for only ONE model to explain "how it all got started"?…

Has it?

Man, that story doesn't half mix up theory and hypothesis a lot. Its one or t'other, in this case hypothesis.
