Since mutations ocuur when a bacteria divides, it is safe to assume that in multicellular species when two cells undergo meiosis, mutations happen too. (If this statement is wrong, please point it out). And since most cells are completely functional without the rest of the body (provided their strata resembles the blood from its species), we can argue they have the ability to adapt to their sorroundings as independent species do (again, Im only assuming, so I may be wrong) by mutation and natural selection. Now, if these statements are true, body cells may evolve and make themselves fitter and therefore, making the individual healthier and less prone to dying from epidemics or poisoning.

Now, a second thought: isnt this process exactly what makes the ability to become somewhat more inmune to some poisons by injecting a growing dose of them gradually?

What makes it itch so much? And what causes it to swell when you scratch it?
This is not asking what you do to stop it itching, nor how to take care of it. I want to know the science behind it.

I asked a Q's and then gave a little tutorial as I ussually do, this bothers people for some reason. I'm somewhat at a loss as to why I hear its to long and there are mistake's, I would like to think that its ussually a good read, but I might be a little to enambered with myself. Anyway it's been my experience that christians are'nt on the same page when it comes to evolution, and I'm used to that. But when I mentioned missing links such as Erectus,Habilus,Lucy,Goliath, and other humans such as Neandethal and the Hobbits the evolution crowd indicated I might be full of it. Well, unless I'm going to believe in the whole Satan is in those scientists and there lying, (crowd) I have on good authority, that scientists discovered a human species on th Island of Flores in Indonesia.They are decendants of Erectus, who then were isolated on the island and dwarfism set in, they evolved to half the size of Erectus. I throw this Q's here for obvious reason's. Have you heard about them,(plural)?

I can see the physical evolution of how we came from monkeys,no problem. My question is how can monkeys still exist if we evolved from them? Usually when a particular species evolve,the initial one no longer exists(specifically because they have evolved). For example, snakes had legs before and there is no existing species of snake with legs.

#1. What characteristics in animals prove they were created rather than they evolved?

#2. How does the unique design of humans and animals rule out the idea that everything evolved from a common ancestor?

The idea that God set up the laws of nature and the structure of the Universe in such a way that all that is spontaneously blossomed into existence is more amazing and spectacular then spiting on the ground and making Adam. The more I learn about Evolution and Science, the more I glorify God for it.
Enoch was right when he described evolution in the word of God.
