This is according to an article published by researchers who examined the mass extinction of apes over the past tens of thousands of years. The researchers found that the brains of large extinct species were on average smaller than those of large species that survived * Their relatively high intelligence helps them deal with the main cause of extinction - human activity

The meaning, as you can understand, is not that there is a mind at the core of the planet that makes decisions for the creatures living on it. Exactly the opposite: in the future they describe, all living beings on earth will participate together in a process that amounts to the creation of one collective intelligence
