How come when you touch something, you feel it where you touched something? Like, if I type, my finger tips feel it...but how? If the nerves send impulses to the brain when you feel/touch than how come you have the sense of feeling where you touched???

Darwinist followers believe that we humans came from apes or thinks we’re a distant cousin of apes. They’ll argue that there is only 1% gap between the human genes and monkeys, but that’s just what nature is; “The 1% difference!” It still does not make us one of them even if there was a sliver of difference. If humans coming from apes were true by evolution due to the survival of the species, then why are there still apes around? Why have they not changed? Dogs are said to have come from wolves and can be crossbred, it goes the same with a Zebra and a horse, a rat and a mouse, and as sick as it sounds, if we humans did come from apes, why don’t we just cross breed human with apes to find out once and for all? I honestly believe it’s not possible though because it is just proof that we’re not related to apes. What’s your opinion?

Arteries
•Carry oxygen rich oxygen from heart to tissues and organs around the body.
•Blood flows through arteries with great force of flow, so arterial walls are thick and flexible. They are made up of three muscle layers, combining of connective tissue and elastic-like tissues. These thicker walls help protect against damage to the artery walls from the high pressure.
•Arteries get smaller and smaller the further they get away from the heart, becoming capillaries at their smallest point.

Capillaries
•Connect arteries to veins
•Carries blood to and from every cell in the body
•Capillary walls are very thin, and are composed of only a single layer of epithelia cells. As the layer is so thin, it allows for the diffusion of molecules such as oxygen, water and lipids to enter tissues. Also, carbon dioxide and urea (and other toxins) can be diffused into the blood for removal from the body.
•The endothelium also uses active transport to transport and other substances that are to
