Male-female ring finger proportions tied to sex hormones in embryo; may offer health insights

Оценок: 50 | Просмотров: 37769
Biologists at the University of Florida have found a reason why men's ring fingers are generally longer than their index fingers — and why the reverse usually holds true for women. The finding could help medical professionals understand the origin of behavior and disease, which may be useful for customizing treatments or assessing risks in context with specific medical conditions. Writing this week in the Proceedings of the National Academy of Sciences, developmental biologists Martin Cohn, Ph.D., and Zhengui Zheng, Ph.D., of the Howard Hughes Medical Institute and the department of molecular genetics and microbiology at the UF College of Medicine, show that male and female digit proportions are determined by the balance of sex hormones during early embryonic development. Differences in how these hormones activate receptors in males and females affect the growth of specific digits.

Taking hormones during pregnancy is how we have men with straight foreheads, narrow shoulders, zero bony ridge above the eyes, small heads, short arms, round jaws ( All female traits) and woMEN with big heads, straight torso, deep set eyes with bony ridge above the eyes, square jaws and shoulders, long arms and Adam's Apple's. Abominations made to order.

I don't believe in any of this. I have a female friend who was born female and has a lovely daughter. I asked to see her hands and both hands her Index finger is shorter than her ring finger. She's definitely female who gave birth to a beautiful daughter. These study's don't prove a thing. They take a group of maybe 50 people and they look at the majority who have either a longer Index finger or a longer Ring finger. For them to do a proper study they would have to look at every humans hands. The length of the fingers has nothing to do with gender what so ever.

pretty stupid. an asshole online said that I was born a man based on my fingers. this bullshit about the index finger (finger next to the thumb) if its shorter than the finger next to your pinky(the ring finger) than it means your male . I said how is it I was born a man ? I bleed every month. I've been pregnant.

Why is this ring-finger-vs-index-finger stuff all over the Web? It seems like every news outlet on the planet seems compelled to print an article or air a 'report' like this one about it. You'd think someone had discovered the cure for cancer, or a way to stop aging. Are we supposed to be fascinated by this? Or is this just 'entertainment news' which expects everybody to be measuring their fingers around the water cooler. If you're interested, measure from the crease at the bottom of the finger to the tip, then read the list of things that the ratio says about you. None of them are things you can do anything about. And don't forget there's also a study that found a correlation between the ratio and stretched penis length. Think of the fun you can have verifying that!

Roy F. I think it's because of people claiming that Michelle Obama is a man
