The article doesn't mention the age of the mother when the family went into isolation in 1936, but judging from the age of the father and the age of the oldest child, she would have been somewhere between her mid/late 20s and late 30s. That could be one reason why she only had two kids in isolation. Also, the family experienced famine, which affects fertility negatively. And the family lived in one room. The lack of privacy may not have been conducive to reproduction.

Which may have also been true during the era 200,000 to 10,000 BC: famine, war, political disturbances, persecution, poor nutrition.

You posted this three times, so two of them were auto-killed.

It was not actually true historically, most of the time people did not have poor nutrition. Sure during "events" like war etc, things got bad.

But most of the time it was not so.
