Also wouldn’t a DNA sequence get more likely as time goes on as it builds from the past and is not uniformly random? In the mokey/typewriter thought experiment

Also wouldn’t a DNA sequence get more likely as time goes on as it builds from the past and is not uniformly random? In the mokey/typewriter thought experiment no previous correct keystroke makes the next keystroke more likely to be correct. However, with DNA/life once it starts the next iteration is more likely to be better since it has the previous success to build upon.
