According to the theory of evolution, humans were always developing in a good direction that was more suitable for human survival.
for example, to the ancient people, the appendix was a very important organ, but it always had problems. that was why many people in the modern era had to remove their appendix if it was infected. since 150 years ago, the appendix had become less important. this was a sign that the human body's genes were constantly changing in a direction that was more conducive to human survival.
However, there were also some bad changes. many women nowadays didn't pay attention to protecting themselves. when they were doing it, men didn't want to wear t-shirts, but they didn't stop them, and they didn't take medicine after. she knew that it was not the right time to have a child yet, but in order to make the man's heart ache, in order to create more blood ties between them, she went to get pregnant and then abort it.
