Moores law and the origin of life

Post by Matt » Mon Nov 02, 2015 12:29 pm

...10 billion years ago apparently. Given our solar system's age of about 4.5 billion years that puts the origin of life on another planet.

A novel approach. Still reading the paper itself but here's a review with a link to the meat.

Very interesting. Looks like a fair few assumptions have been made along the way...

I've always understood that pace of evolution is very variable and largely driven by factors like climate change. And isn't the fossil record a rather good argument against this idea?

The immediately obvious flaw is the assumption that evolution = greater complexity. This is not always the case and in particular the great extinction events knocked complexity back. In times of adversity the simpler life forms survive. Therefore, the average complexity increase over the last 2 or 3 billion years does not preclude a much steeper increase in complexity in the first few hundred million years of life.

To get a better comparison you’d need to allow for, or ignore, the big extinctions; or else you need to look at what would happen to Moore’s Law if there had been some massive transistor shortage events in the last 50 years. Or something.

It seems that niches left by extinct species are soon, (in relative terms), filled by adaptations in others. There are plenty of species still around that haven't changed much in hundreds of millions of years. The nautilus springs to mind; they haven't had to.
