Learn about blood types and epigenetics - part 4

That's what your hand looks like when you are a fetus, but basically, it's interesting because fingerprint patterns are a combination of genetics and epigenetics. There are some elements to the pattern that are definitely genetically involved, but aspects of how the patterns crunch as the hands change are epigenetically determined as well. So for instance, changes in fingerprint patterns often reflect changes in the development environment of the fetus, acidity, sugar, all things that even go into making you left-handed and stuff. Basically, I mean, here you can see the three, essentially three basic fingerprints, right? There is a Whorl, looks like a round thing, there is an Arch, it looks like a little hill, and there is a Loop, it looks like a little lasso. We have wonderful films, I have just done in QuickTime that are going to be on the Genotype Diet website to take people through this. I am going to share one with you later. You can look at your head and see all sorts of interesting things. Is your head long? That means you are Dolichocephalic. Is your hear broad? It means you are Mesocephalic. Head circumference is also a reflection of certain developmental aspects. It turns out that the shape of the head correlates overtime with epigenetic influences on nutrition as well. For instance, in general, our human race, our heads have become more and more elongated if you study skulls. In essence, this is taught to be related to changes in nutrition. It actually is interesting because if you study skulls from the ancient time to the middle ages, it went the other way, so as people were more and more compromised in terms of their health, their heads broadened. I am not going to spend a lot of time on Somatotypes, but we do as people to understand and be able to predict whether or not they are more endomorphic, mesomorphic or ectomorphic. The reason being is that it turns out that even though Sheldon at that time didn't know it, those basic somatotypes correlate with the relative amount of those three types of germ tissues in the body. So, for instance, an ectomorph is kind of a more gangly or leaner person tends to have more ectoderm tissue. Of course, you know the thing about Sheldon was, of course, a lot of his characterizations, he was off on the Holy Grail trying to find psychological core with somatotypes, but it turns out that the phenotype manifestations, simply in terms of body planning, those Hox Genes in developmental aspects are far more interesting than anything he could prove with psychology. Your jaw also influences things, the jaw angle here, whether it's wide or narrow, has reflections. There is lot of work done in the 40s on them. The spaces between the legs, comparing the trunk height to the upper and lower leg height, add it together and then the upper leg to the lower leg tells you a lot about -- trunk to leg is an indication of metabolic thriftiness, upper leg to lower leg is a reflection of insulin like growth factor levels in the first couple of months of life. Growth factor levels are a big influence on susceptibility to certain types of neoplasms and heart disease. So people who have very -- if you ever look at babies, babies have very long upper legs, but they have little short lower legs, which is why they look so cute when they walk. But when they get older, the lower leg elongates as growth factor level start to enhance the uptake of calcium. Well, those growth factor levels have effects on liver function, they have effects on immune function, they have effects on blood cell and a variety of different things. The insulin-like growth factors in terms of insulin-like growth factor 1, growth factor 2, have a tendency to remortalize cells and so often by delaying -- this is more for the girls in the back there, delaying Apoptosis you wind up essentially producing cells which essentially have problems with regard to a prolonged resistance to Programmed Cell Death later in life. So that's why there are a
