If Homosapiens survived the last mass extinction how is there almost 8 billions Humans now? Are we all related? Is every human related in some way?
In: 80
Yes we are all related. As for being 8 billion now, most of that growth happened in the last 60-70 years of history. Human population slowly trended upward toward 2 billion or so, as humans slowly populated the earth and advanced the technology. But population really took off when artificial fertilizer started being used en masse. Food availability shot up, and made supporting a large population possible. I’d you look at charts, you can see the population trend make a sharp move up after that point.
