>>15447662If you look at most animals that have evolved here they have made drastic adaptations to survive.
Surviving sometimes comes at the cost of intelligence.
The koala is a prime example, it adapted to eating eucalyptus leaves and let everything else slide. They basically eat, sleep, fight and fuck... there is literally no energy left to do anything more.
The ancient aboriginals found themselves in the same situation and adapted to survive with fuck all resources.
