If cancers prevented propogation then either a defense mechanism could have arisen or the species would have serious problems. However cancer effects most people well after they are able to have children.
Tell the kids who have this. And their number is growing. And in the evolution theory, the strongest survive. Or is that only when it supports the theory?
Mutations occuring in a grown adult cells as in cancer, do not contribute to the genomes of their children.
Studies have shown that cancer genes can be passed from parent to child. As well as other diseases.
The immune system does not use a checklist to determine if a specific organ is meant to be there or not. It works by reacting to surface proteins on individual cells. In an organ that has been transplanted these surface proteins are not identical to those of native cells. Thus imuno suppressant drugs are needed to keep the immune system from tearing apart the transplanted organ.
If we all evolved from the same source, how did such uniqueness between each other evolve between the same species? Uniqueness shows a Creator design. Evolution relies on likeness for relation to each other. The evolution process itself suggest that we should not be so different, but yet we are.
You may be accustomed to thinking that electricity is some sort of mystical man-made phenomena. But all things in technology take advantage of natural phenomena. Cells taking advantage of electrical conductivity may seem surprising to you but it is in no way unnatural.
Anything that produces electricity, also produce a frequency and a magnetic field of sorts (weak or strong). In the case with humans, each cell in the body produces it's own frequency. Why? Because it becomes charged through the nervous system, and only like cells can produce like frequencies. The brain itself produces enough energy to run a 10 watt bulb. You take and add up all the different cells in each human, and because this number has endless combinations. The frequency the body generates itself is unique to each human.
The human body consists of a huge number of cells, on the average about one billion cells per gram tissue. The whole body contains many cells that are not alike. Red blood cells, white blood cells, bone cells, nerve cells, all the different organ cells, etc... And not two humans have the same exact amount of these different cell combinations. Through all of this, and what makes us more individual than the same, only points to a Creator.
The fact that many organisms have fundamental commonalities in their nervous systems suggests that multicellular mobility requires some sort of sensory processing.
There is nothing common about the brain, and the rest of the human body being able to process some type of communication.
Example: It has been recently found that the heart can communicate to the brain in four different ways.
Neurologically (through the transmission of nerve impulses), biochemically (via hormones and neurotransmitters), bio-physically (through pressure waves) and energetically (through electromagnetic field interactions). Communication along all these conduits significantly affects the brain's activity.
It is now believed that this is why our heart hurts when we lose someone near and dear to us, or we break up with someone we were attached to. Because they are finding that the heart plays a role in our emotions through this extra way of communication.
For one organ to be able to do this, how would natural selections make the selection required for this to happen? When it's main function is to only pump blood?
