This is an interesting question, and one we should consider quite seriously, especially when it comes to our health. In order to answer it accurately we need to have a look at our estimated evolutionary timeline.
- Life as we know it started around 7 million years ago, we were given the name Homo genus.
- Around 2.5 million years ago we split from our ape cousins and were given the name Homo erectus.
- Around 160,000 years ago we appeared in East Africa and were given the name Homo sapien. (this is pretty much who we are today….)
- Around 60,000 years ago a small group of us decided to migrate.
- Around 45,000 years ago we found what is now known as Europe and settled there.
- Around 30,000 years ago there was a population boom.
- Around 20,000 years ago we decided to explore and found North America.
- Around 12,500 years ago we had populated pretty much most of the planet.
- Around 10,000 years ago we began to become ‘civilized’ and began cultivating crops and farming in the Middle East. (this is where it all started to slow down)
- Around 4,500 years ago the same happened in North & South America
