虽说每个人都是独一无二的,但我们都有两个眼睛一个嘴巴,基本的体态特征是一样的。看到别人多了一只手指我们都觉得惊奇不已,更何况下面这些“闻所未闻”的体态特征呢~
是不是很好奇?那就跟小编一起来看看有那些奇特的体态特征吧~~
1. No wisdom teeth
没有智齿
20% of people don’t have wisdom teeth, which is considered a normal variant. Their occurrence varies across different populations. For example, almost 100% of indigenous Mexicans don’t have wisdom teeth, while virtually all Tasmanian aborigines do. The difference is related to the PAX9 gene (and perhaps other genes).
20%的人没有智齿,人们认为这是正常的变异。不同的民族智齿出现的概率会有所不同。例如,几乎所有的土著墨西哥人都没有智齿,而几乎所有的塔斯马尼亚原住民都有智齿。这种差异与PAX9基因(或许还有其他基因)有关。
2. Blue eyes
蓝眼睛
It has been suggested that the blue eye color is due to a mutation in the HERC2 gene that leads to reduced melanin production in the iris. Only 8% of all people have blue eyes.
据说蓝眼睛的颜色是因为HERC2基因突变导致了虹膜内黑色素的减少而形成的。只有8%的世界人口有蓝色的眼睛。
3. Morton's Toe
摩顿趾 ; 摩顿氏趾
10% of people have Morton s toe: a foot structure where the first toe is shorter than the second. Interestingly, the Statue of Liberty also has feet of this kind.
10%的人有摩顿趾:一种脚的结构——第一个脚趾比第二个脚趾短。
有趣的是,自由女神像也有这样的脚。
4. Hair whorl
发涡
8.4% of people have counterclockwise hair whorls on their head. If you belong to the 10% of the population who are left-handed, though, your chances to not be like the majority are 45%.
8.4%的人头上有逆时针的发涡。如果你属于占人口10%的左撇子人群,那么你有逆时针发涡的几率是45%。
5. Sneezing
打喷嚏
25% of all people have an unusual reaction to sunlight: sneezing. This phenomenon even has its own name: photic sneeze reflex.
25%的人对阳光的反应不同寻常:打喷嚏。
这种现象甚至有专属的名字:光喷嚏反射。
6. Single palmar crease
断掌
The single transverse palmar crease, or the 'simian crease,' is found in 1.5% of the population (more often in males) and is a hereditary trait.
在1.5%的人群中发现了断掌(通常是男性),这是一种遗传性状。
