In Babies
What does it mean if my baby has a simian line?
A simian line (or palmar crease) is a single line runninghorizontally across the palm of the hand, instead of the two thatare usually featured in humans; the word comes from t…he fact thatsimians (or monkeys, apes, etc) have the same feature and is not inreference to the fact that we were "descended from apes" (nor is tobe taken as proof of such either way). Palmistry systems based in Europe are unused to accounting for sucha palm, and so conventionally ascribe to them qualities of extremeintelligence (genius) or extreme sociopathology (insanity,criminals). Japanese and Chinese palmists however, explain that those with the'masusake' hand are of high repute and prone to be talented artistsand scientists (genius). The middle-of-the-road explanation is that it indicates a personwho has a determined and "intense" personality that can focus onsomething very intently, and who might require a bit of extra careor attention(ie: Down's Syndrome, Bi-Polar Disorder, Autism, etc). However, there is no hard proof that swings a definitive answer ineither direction, and the simian line seems to be "just one ofthose things" that people have which makes them different from eachother in certain ways; a lot of people even only have it on onehand, usually the left, oddly enough! Although the presence of simian lines is apparantly higher amongNative Americans and Asians, this does not seem to be a reliableindicator of having any sort of Native American or Asian lineage inyour genetics...mostly because it is found in all cultures. Health Considerations Simian lines are featured among a significant number of people withDown Syndrome and other disorders, such as Bi-Polar, Autism orFetal Alcohol Syndrome, etc, so without any other explanations, itmight be a good idea to have your doctor check your baby for anysymptoms...but remember that there are plenty of "healthy" peoplewith simian lines (about 5% of European population has them). Also note that from *my own* observations, and without deeperinsights into the differing *types* of "simian lines", I've noticedthat a lot of people who come up with an online search for "simianlines" don't actually *have* what I would consider a "true" simianline...more of a variant of one, if at all (ie: there's still adistinct second line, but small or faded, etc).
