Okay, so I know this might be a bit hyperspecific, but I don't know where else to ask it. I'm working through a microbiology lecture, and the professor says the the B strain of E. coli has a tRNA suppressor that allows it to transcribe phage genes that have any nonsense mutation. That seemed a bit vague, so I decided to look it...
I know otters blow bubbles into their fur to isolate themselves, but this also makes them extra buoyant. For the babies this is quite handy (less drowning etc) but for adults idk if it really helps.
It really depends on the fur texture probably, seals are also coated in fur but streamlined to perfection.
The atmosphere sure changed a lot because of life, which might have had its effects on incoming solar radiation? Which might have changed the temperatures of some ocean currents/continental plates? I don't think it would differ significantly
tRNA suppressor mutation to transcribe nonsense mutations

Does having fur help or hinder animals like otters/beavers/polar bears when they swim about?
If life never emerged on Earth, would the continents still be more or less the same today? In other words, does life affect the formation and movement of continents significantly?
