Because STUDEN of history, if they tried to explain it to you, especially after you saying something like blood cells will float away without arteries, they are not going to bother explaining Genome fusion, RNA world hypothesis, or the Darwinian transition. It would be like me, trying to explain the inner workings of an ipod to a penguin in South AFrica.
Okay then, feel free to enlighten all of us how Genome fusion, RNA world hypothesis and or the Darwinian transition explains exactly how a single cell organism evolved into a multi celled organism. I'd love to hear how that happened. If you can't explain it then please provide a link that does.
The Reader's Digest version is that the unicellular organisms clumped together into a single community. With a community that tight-knit, it's beneficial to develop specialization. From there, it's not a big stretch to fusion.
Unicellular organisms by their very nature aren't very motile and their primary survival tactic is to reproduce as quickly as possible. With multicellular organisms, they can defend themselves and go after their own food. They have a big advantage.
That's not to say that unicellular organisms are less evolved than we are. For eons, life never got more complex than the single celled so it is obviously a fantastically successful way to live.
