"Damn, Paul! That’s a big question. Here is my magazine response:
Cells communicate through their own language of chemical signals. Different compounds, such as hormones and neurotransmitters, act like words and phrases, telling a cell about the environment around it or communicating messages. When the pancreas detects a person has just eaten, for example, it releases the hormone insulin to tell other cells in the body to remove glucose from the blood. Just as a person needs ears as much as a mouth to have a conversation, cells use receptor proteins either on the outer cell wall or inside the cell itself to “hear” different signals.
Once the signal chemical binds to a receptor, that protein turns on a signaling cascade in the cell that ultimately leads to the cell’s response. Every cell has receptors that can detect a lot of different signals, so they are constantly bombarded with biological conversation. Imagine being in a room and having everyone talking at you at once! So how does a plant use cellular communication to grow toward sunlight? The growing tips of plants produce auxin — a hormone that tells cells to grow and divide — which is then sent to the rest of the plant. The shady parts of a plant receive more auxin, which causes those cells to elongate while the sunny-side cells don’t. When one side lengthens while the other side stays the same, the plant will bend.
I wanted to note, though, that this is the super-short, incredibly oversimplified response. Cellular communication is inexplicably complicated. For example, these are the pathways associated with a single receptor, the B cell antigen receptor...."

MY COMMENT:
This diagram illustrates the pathways associated with just a single receptor??? IT PRACTICALLY LOOKS LIKE A COMPUTER CIRCUIT BOARD, FOR CRYING OUT LOUD!!! And we are supposed to blindly believe that it was all designed by natural selection which has no consciousness, awareness or intelligence? It all happens by "random chance"? Like tossing dice? Cells just so happen to communicate...by mistake?
A throw of the proverbial dice of a completely unintelligent natural selection just so happened to form into Leonardo Da Vinci? Does science have repeatable, observable scientific experiments demonstrating this or do they only have BLIND FAITH to prove this preposterous assertion?
Well, I've looked into this matter. ALL THEY HAVE IS BLIND FAITH that it is so!
NOT ACCEPTABLE FOR SCIENCE!!!!
THEY'VE GOT A LOT OF NERVE PUTTING DOWN RELIGIOUS BELIEVERS!!
THIS PROCESS IS MUCH TOO COMPLEX TO HAPPEN BY COMPLETELY UNAWARE RANDOM CHANCE!!
If you disagree be prepared to back up your stance with repeatable, observable scientific experiments of just keep your fingers shut, atheists!!!
