Im sure There was a time in history when there was just half a milion humans on the planet. These people made kids and the population increased. They are our ancestors and we are healthy. So why is it a problem with Iceland who has half a million population, they have to watch out bc they might be realated and they may produce bad offspring. Before iceland was even discovered the populatio must have been even smaller and the people were okay? Please explain it to me, I must be stupid.

Modern people in Iceland just don’t like to take chances when it comes to their children’s health. While ancient humans didn’t have a choice and just ended up with “bad offspring” occasionally. It doesn’t matter for the population overall if some number of families get unlucky, it only matters to those families.
