Firstly, in terms of appearance, Wa Star People have two hands, two feet, and one head, which is basically similar to humans, but their physique is slightly smaller, with the average height of Wa Star adults being around 1.6 meters.
Unlike humans, their two ears are slightly pointed and located on top of their heads, rather than on the sides like humans.
Furthermore, regardless of gender, their skin color is uniformly white, but it is not an unhealthy white; rather, it is a rich, creamy pure white like milk.
Under normal circumstances, there are usually some differences between men and women, as with humans where men grow beards and Adam’s apples, making it easy to recognize their gender from these clues. However, Wa Star Civilization is entirely different; the men and women of Wa Star Civilization do not have significant differences in appearance, at least not noticeable ones like beards or Adam’s apples seen in humans, nor do they have any distinct female characteristics. Their facial features and hair quality are quite similar, without any gender phenomenon of being rough or delicate.
This makes it very difficult to distinguish between men and women in Wa Star Civilization.
If one has to find a comparable body type, then the Wa Star People somewhat resemble the androgynous style on Earth; if not observed closely, it is very difficult to tell whether they are male or female.
When an Electromagnetic Star Person first met the Wa Star man Yike, he thought Yike was a woman until he heard the conversation and realized there was a gender difference, then recognized that Wa Star Civilization is not solely comprised of women.
Overall, the Wa Star Civilization does not exhibit obvious sexual dimorphism like Earth Civilization; their men and women converge towards similarity, showing a trend of homogamous development. Simply put, if men and women on Earth are like the north and south poles of a magnet, the men and women of Wa Star Civilization are without magnetic poles.
Given this, why does Wa Star Civilization still distinguish genders?
Initially, this puzzle also troubled the scientific team of the Wandering Alliance, but after research, the scientists finally learned that there is indeed a difference between the males and females of Wa Star Civilization, located on a specific part of their bodies.
From a biological perspective, their sheer appearance is quite similar to that of Earth’s males and females, which is the only visible difference on the surface; if that particular part is not visible, it is generally difficult to distinguish the gender of Wa Star People. Of course, this is for aliens, as Wa Star People who have lived together for years can easily recognize each other’s gender at a glance.
With this research, scientists became vaguely knowledgeable about the basic situation of Wa Star People and, based on the environment of Wa Star, they deduced the phenomenon of gender convergence. Furthermore, the genes of Wa Star men and women have also proved this point, sharing 99.5% similarity, higher than that of humans, which is the main reason why their appearances look very similar.
However, there still remains an unexplained issue: why has Wa Star Civilization formed a social structure of female superiority and male inferiority?
From the perspective of Earth People, the data gathered so far cannot explain this point, because on Earth, any dominance is historically and environmentally induced. Like the matrilineal societies of ancient times where females led because that period needed women to reproduce offspring, but as the living environment stabilized and labor became more significant in society, physically stronger men began to take dominant roles, persisting until the Industrial Revolution on Earth completely overturned this inequality.
Compared to the developmental history of Earth Civilization, Wa Star Civilization undoubtedly lacks some key factors.
To clarify these key elements, the scientific team of the Wandering Alliance continued their in-depth research on Wa Star People, eventually discovering the crucial factor.
It turns out that in Wa Star Civilization, it is the men who are responsible for pregnancy and childbirth, not the women!
The scientists had been in the blind spot of conventional female pregnancy, hence overlooking this point.
However, precisely because Wa Star men need to carry pregnancies, they have historically had fewer labor hours, naturally resulting in a lower social status. Additionally, pregnancy leads to a reduction in the lifespan of Wa Star men, averaging about ten years less than that of Wa Star women, thus adding up these factors slowly shaped the social phenomenon of female superiority and male inferiority in Wa Star Civilization.
When this result was discovered, the entire Wandering Base was in an uproar.
Because the Wandering Alliance had been wandering in the Universe for so long, it was the first time encountering a civilization where men are pregnant, a situation not only rare among intelligent civilizations but in the animal kingdom as well, with the entire Earth’s biosphere having only seahorses where males are pregnant.
The fact that there exists a male-pregnant civilization in the Universe is indeed a great miracle.
Regarding the mystery of why Wa Star men are pregnant, scientists after research finally discovered the truth.
It turns out that in the body structure of Wa Star men, there exists an organ called "abdominal sac," equivalent to the human female’s uterus, except the sac is not found in Wa Star women, so the burden of pregnancy naturally falls on Wa Star men.
However, since it is Wa Star men who get pregnant, one can imagine that the reproductive methods of Wa Star People are also quite different from what humans understand...
This was also the main reason why the Electromagnetic Star People suddenly died during the initial reproductive experiment by Wa Star Civilization, because Electromagnetic Star People are not Wa Star men.
In addition, scientists discovered that the reproductive success rate of Wa Star Civilization is a staggering 100%!
One last point, the Wa Star People are not mammals.
They do not require breastfeeding when young, which is also the fundamental reason why they haven’t evolved such parts.
