Is nature invoking ‘survival’?

Yes. The sequences inhabit an environment where resources are limiting and predators abound. Small differences between the sequences can result in success or failure.

[Heartlander]

But where does ‘survival’ exist? This is not a mindless mechanism as required in ‘natural’ science. A snowflake has no survival instinct. Are you saying that there is a difference because something ‘lives’ but was put together in just a different sequence than a snowflake?

Snowflake -> natural mechanisms -> no survival
Organism -> natural mechanisms -> survival -> teleology (unless an organism is not intended to survive)
