I was taught over and over ...

I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.

Quotes from the same author

The accumulation of genetic mutations were touted to be enough to change one species to another….No. It wasn’t dishonesty. I think it was wish fulfillment and social momentum. Assumptions, made but not verified, were taught as fact.

To me, the human move to take responsibility for the living Earth is laughable - the rhetoric of the powerless. The planet takes care of us, not we of it. Our self-inflated moral imperative to guide a wayward Earth, or heal our sick planet, is evidence of our immense capacity for self delusion. Rather, we need to protect ourselves from ourselves.

The notion of saving the planet has nothing to do with intellectual honesty or science. The fact is that the planet was here long before us and will be here long after us. The planet is running fine. What people are talking about is saving themselves and saving their middle-class lifestyles and saving their cash flow.
