Perhaps you have heard of a child born with "crab hands" instead of having five fingers, his arms end in two thick appendages that look like the claws of a crab. In the Philippines, many people probably would blame this on 'paglilihí'.
According to a longstanding belief on Philippine 'paglilihí,' when the will or desire of a mother during early pregnancy were not met, the conditions of her unborn child would be adversely affected, and worse, what he wished for and eagerly eaten during the his 'paglilihí' would influence the physical characteristics of the child. People who believe in these cases would certainly argue that the child's mother "crab" when he had feasted on crabs at the stage of 'paglilihí'. In fact, the Philippines, claims as "'pinaglihi knows palak, luya knows dwende know ...'" [designed frog, ginger, dwarf ...], or" loob' sa sama ng '[to ill feelings] are very common. However, thanks to advances in medical science for the many myths about 'paglilihí' are gradually dispelled.
Medical science now offers us a better understanding of the term 'paglilihí', which refers to the period from conception through the first trimester of pregnancy. At this stage, experiences pregnant hormonal changes affecting their bodily functions. The desire, hypersensitivity of taste and smell, nausea, morning sickness and mood swings are common symptoms of the changes. Some psychologists also argue that the hormonal fluctuations of pregnancy can make a woman more emotional, you can begin to feel neglected. Because the stomach begins to relax, may feel fat and unattractive. To reassure herself, she may seek the attention of her husband, more frequently, to, in general, asking for some hard to find delicacies.
The health of the mother during pregnancy has indeed many effects on fetal development. For example, women during pregnancy, were malnourished, did not smoke or drink, or had somehow ingested unprescribed drugs had a greater chance of delivering children with birth defects. And to put the case of the "crab child" to any of these factors is medically correct.
physical characteristics or hereditary traits are passed from parents to children with deoxyribonucleic acid (DNA) the genes contain. The fundamental hereditary material in almost all organisms, DNA determines the overall composition of an individual, such as bone structure hair color, complexion, height, and even the shape of hands.
In genetics, or the science of heredity and the relationships of organisms resulting from the interaction of their genes and environment, there is a process known as 'mutation'. This abnormal process results in the alteration of genetic material transmitted to offspring. It may be spontaneous, that is the result of accidents in the replication of genetic material, or induced by external factors like temperature, X-rays, ultraviolet light and chemicals. Its results are likely congenital abnormalities, physical deformities, and other aberrations. And one or a combination of these external factors and spontaneous is the most likely reason some children are born with "crab hands" or any other unusual physical characteristic.

In 1977, in a remote province of China, Yu Chenhuan surprised his parents when he was born with long hair and silky on almost his entire body. His condition continued to mystify all as he grew into a very hairy boy. People who believe in the myth of 'paglilihí' simply dismiss Yu as a case of a child conceived [monkey 'pinaglihi unggoy know']. However, medical experts who evaluated her was discovered that Yu was suffering from a condition known as 'hypertrichosis.' hirutism Also called ',' this is a rare genetically transmitted disease X-linked dominant, characterized by excessive hairiness in both localized areas or across the skin. / © 2004 elf ideas
