It’s feed back only in the sense that it can be seen as a success or a failure by an independent observer.
It’s not like a tree can see that last year’s seeds weren’t very good and try a different mutation this year.
Genes are not self aware, mutations do not have an end goal and survival simply comes down to chance.
There is no knowing or feedback.
Mutations are random and there are many more failed mutations than successful ones.
You only see the successful species for that very reason, the failed ones have not been able to compete or pass their genes on at an appropriate rate.
“but Trump’s a raving lunatic!” Sticks fingers firmly in ears
Edit: presumably I’m getting downvoted because Trump has set the bar so low that we’re ingnoring the common opinion that Biden should retire gracefully rather than acting surprised when Trump wins and getting forced out anyway.
Trump being a raving lunatic doesn’t make it OK to not find a candidate that doesn’t belong in a care home.
Copium. I hate Trump but this is absolute basics when it comes to world politics.
It was a huge gaff.
Google image search says it’s a desk calculator with electron tubes.
I think there are many great reasons to not vote Trump, but that doesn’t mean you have to like voting for Biden
