More about how evolution works: multicellularity (Evolution)

DAVID: As cell puppets talk in your play, it is my point that your dialogue is exactly on point. Complexity builds on complexity. Bacteria have never gone extinct, but multicellular forms always do. If survivability were an issue, multicellularity would never have occurred. And while the bacteria are talking, from their easy living standards, they wonder why we like being so complex. Small cell chauvinism on display. By the way, we have much agreement. Complexity goes hand in hand with improvement, if designed that way.

dhw: Your last sentence is “exactly on point”. Complexity without a purpose makes no sense.

The fact that I always espouse complexity leading to the human brain is left out of your discussion. Of course complexity without purpose is nonsensical.

dhw: Complexity for the sake of improvement makes perfect sense. Improvement “builds on” improvement. According to you, until 30,000 years ago ALL improvements were geared solely to survivability, so it is absurd to say survivability was not an issue.

Species survability is always a major issue.

dhw: Evolution has advanced through the drive for survival and/or improvement. Doesn’t that make perfect sense?

Complexity and improvement are most important. Survivability results from those two.
