I'm surprised that mammals evolved to not regrow teeth. You'd think it would be a significant advantage.
I wouldn't imagine it'd play a role in reproducing though. It may help ones ability to live longer, but they have probably procreated long before tooth loss has become a major issue of well being or mortality.
It’s also only recently that we’ve been living for so long.

this is misleading, the article starts by saying that life expectancy was 30-35 but then goes on to say that this is the average lifespan, which includes the fact that most people died in childhood.
When accounting for that, the average lifespan becomes at least 50 years old.
