Yes, it is possible for slight anatomical variations to occur in a human body. There are several examples to quote. First example, the heart is normally present on the centre left side of the body, but in rare cases it is present on the right side. This condition is called Dextrocardia. Second example, some people have variation in the way their brain is wired. This variation can lead to the individual being an excellent learner of music, or the ability to perform quick mathematical computations.
