Do all humans have the same number of veins and arteries? If so, how does the body know how many and where to make these veins and arteries?
In: Biology
I just want to say that apparently, no cells in our body is farther than 5 cells to a blood vessel. Another fact I liked is that blood vessels always follow a fractal pattern. Same for a lot of structure in every form of life. Instead of coding for every cells in the body ( DNA is not long enough to code for every cells in a body) there is instruction for a fractal pattern. The DNA code for the recipee, where to start and where to end. Other stuff in the DNA’s environment dictates when the recipe is made.
“The DNA is like a cake recipe. If you want to make a cake, here’s how. It doesn’t decide when it’s made.”
Quote from Robert Sapolsky, IIRC.
