Do you understand how the process works? If people have mitochondria from both parents in all their cells, and scientists formulate theories based on the belief that they only get them from their mother, that might throw off their conclusions just a bit, agreed?
Theories are just that, theory. There are so many assumptions being made in science all the time, that just about anything they come up with that is reasonably close to reality is as likely due to dumb luck as it is the methodology.
We can't even explain the most fundamental aspects of reality, matter and consciousness. How arrogant do we have to be to believe we can explain things that are even more complicated if we can't understand the basics?
That being said, I'm not anti-science. Mostly anti-idiot scientist and idiot-scientist believer, which is most people. All science should be held with an extreme degree of skeptism. Everyone should understand that, and behave accordingly.
Sorry, just ranting. It's not directed at you. I enjoy reading about new scientific discoveries as well. It's like getting a finger painting from a kindergartener.
