Old Worlds: Africa, Europe, Asia & Middle-East
...their 'mascot' was the CAVEMAN: physically strong, but mentally weak.
It was this Mascot that the Old Worlds aimed to rise above as an evolutionary achievement into the future.

New Worlds: Namerica, Samerica, Sahul (Aust, etc) & Oceania
...their 'mascot' is the ALIEN: mentally strong, but physically weak.
It is this Mascot that the New Worlds aim to rebel against and attain physically health and strength into the future.


So if you wanted to succeed in the Old Worlds -> you enhanced your mind and ate from the Tree of Knowledge.

But in the New Worlds, we see the path to success in a complicated era, to eat from the Tree of Life and attain the body and breeding of a better immortality.


...in the Old Days: Life was physically harder, but mentally simpler.
...in the New Days: Life is mentally more complex (rise in mental health issues), but physically more easier (machines do the work)
