If global warming continues and the polar ice caps melt, the sea level will rise sharply, drowning everyone in the sea. By then, lengthened webbed fingers (and toes) will help us swim better. ? 2. Fat gain
The water we will live in in the future is not always warm, especially in the depths. In order to keep the body insulated in a wider underwater area, we may bring baby fat into adulthood. Well, it's quite warm. ? 3. Fish gills
We often feed in shallows and may grow artificial gills one day. ? 4. Chest cavity becomes smaller
Artificial fish gills can help breathing and absorb oxygen in the surrounding waters, so our vital capacity will gradually decrease. Since you don't need such a big lung, you don't need such a big chest. ? 5. The third eyelid
In order to have better vision in dark and hazy water, we need something better than goggles. Therefore, we may evolve the blink membrane (the third eyelid that protects the eyeball underwater), just like an alligator. Isn't it terrible? ? 6. The arms are longer and the legs are shorter.
What if our future residence is not the underwater world, but another planet? In fact, this matter is not out of reach. If we really move to a strange planet, then we will probably lengthen our arms and shorten our legs in order to better walk in low gravity. ? 7. The chin becomes smaller and the teeth become less.
Who needs a mouthful of white teeth when we eat with straws or pills? Liquid or pill food will free our mouths, make our chins smaller and have fewer teeth. ? 8. Nose and face are getting bigger
If people live to the second ice age, then in the case of a sharp drop in the earth's temperature, in order to heat the inhaled cold air, we are likely to evolve a larger face and nose to increase the size of the nasopharynx. The nasopharynx is located behind the nose and can heat the air. ? 9. Pale skin and hair
Less sunshine means less intake of vitamin D, which is necessary for body function. In order to better absorb vitamin D, our skin and hair will become paler, thus absorbing more sunlight. ? 10. Thick body hair
Unfortunately, in this environment with almost no sunshine, snow-white skin and hair are not enough to keep us from freezing to death. So, what can guarantee our warmth and survival? Tons of body hair! ? 1 1. Opposite big toe
If long arms, webbed fingers and thick hair are not enough for super sexy beasts, please enjoy the last point: low gravity will make it difficult to walk, so we will grow opposite big toes to enhance balance.
