I think this sounds reasonable until you really consider Earth's history. We've gone through far more radical changes in environment - not only in terms of temperature shifts from ice ages to worldwide saunas but also in terms of geographic change as what was presumably one land mass gradually divided into many, land bridges between the newformed continents disappearing, even things such as the oxidation of our planet which resulted in the extinction of nearly all life. Yet, through it all - only one species managed to evolve anything like our cognitive and developmental ability. Quite peculiar in many ways.
- acollins1331 7y agoThere were lots of cognitive human like species. I.e. neanderthals etc. They're just dead now.
- rjf72 7y agoThe Neanderthals lived hundreds of thousands of years longer than the entire existence of homo sapien. Their peak technological development was stone age, which sounds even nicer than what it is. Pound two rocks together, notice sharp pieces fall off, use them -> you're now in the stone age. And, contrary to misinformation driven by mass media - there is no clear evidence they engaged in any form of art, adornment, or generally symbolic behavior. [1] Extremely high rates of traumatic injury among the discovered remains also implies that in their hundreds of thousands of years of existence they failed to even refine their hunting technique.
