A slim waist, curvy hips, and long legs—if you take a photo of such a figure and ask anyone on the street, the answer will always be:Beautiful! So beautiful!! Extremely beautiful!!!Especially when a row of long legs stands in front of you, making it impossible to look away and you shout at the top of your lungs, it's even more stunning~ However, we must delve into this issue from a scientific perspective:What exactly makes humans so enamored with long legs? Is it simply because long legs are rare?
Some believe that the reason long legs are only favored by a few is because their genes are superior.
However, biologists couldn't sit still; long legs are not due to good genes, but rather"poor genes".
Yes, you heard that right. This is the result of their recent research. Doesn't it sound quite mind-blowing? The long legs you envy are the result of "poor" genes, which brings a subtle sense of melancholy.
Ahem, here's the situation: Humans first appeared on the historical stage about two million years ago, just as the Earth was entering the third ice age, with extremely low global temperatures. The long-legged family you envy suddenly became a disadvantaged group. There are two reasons:
1. Because their legs are too long, heat is more easily lost, making them more likely to freeze to death in cold weather;
2. Also because of their long legs, their overall center of gravity is higher, making them more likely to slip and fall in icy conditions, leading to fatal fractures. (In prehistoric times, fractures could indeed be deadly)
In summary, during the third ice age, this massive natural selection process favored the "short legs" gene, greatly enhancing the survival ability of the human species. Hence, long legs became increasingly rare.
However, according to a research paper, neither too short nor too long legs are ideal,medium-length legs are the best.
Disadvantages of having legs that are too long:
1. Possible genetic disorders, such as underdeveloped seminiferous tubules and Marfan syndrome, are associated with long legs;
2. People with very small torsos may have poor lung function;
3. Long legs may indicate that a man has not yet reached sexual maturity. (This statement shocked Xiao Jian, who has legs 1.8 meters long)
Disadvantages of having legs that are too short:
1. Higher risk of cardiovascular diseases and type II diabetes, with higher levels of triglycerides and insulin resistance;
2. More sensitive to conditions like malnutrition;
3. Can't run fast, which is disadvantageous for hunting, avoiding predators, and dealing with rivals.
If you are still obsessed with long legs despite all this, how do you explain your love for various short-legged creatures? Why do you think having short legs is ugly? Loving yourself is the most important thing.
