Where Reincarnation and Biology Intersect is a 1997 book by psychiatrist Ian Stevenson,[1] published by Praeger.

[2][3] Ian Stevenson examined reports of people in different parts of the world who claimed to remember past lives, mostly young children.

He explored the idea that "birthmarks and other skin lesions and abnormalities may provide evidence of cutaneous injuries sustained in a previous life, thus supporting the notion of reincarnation".

[4] Stevenson calls some cases investigated "unsolved," where no deceased person has been found to match the birthmarks and memories of the child.

Excluding unsolved and questionable cases, about 90 cases remain where there is a "correspondence found between birth marks on the child and similar marks or distinguishing features present on the body of the reincarnated personality during their lifetime, such as wounds, injuries and other stigmata".
