This is the last of the four part series about the Edge discussion between Lee Smolin and Leonard Susskind.

I previously discussed the physics and the philosophical issues. You will have by now understood who won the battle in my eyes. However, I would like to use this final opportunity to stress that we have yet again a clear showcasing of that it is, as so often, sufficient to merely analyze the style of argumentation in order to figure out who is not to be trusted.
A million years is a blink of an eye in evolution but that doesn't mean newer genes matter less in life itself.    
A geophysicist has made the first-ever measurement of the strength of the magnetic field 1,800 miles underground - inside Earth's core.

The magnetic field strength is 25 Gauss, they say, 50 times stronger than the magnetic field at the surface that makes compass needles align north-south, the middle range of what geophysicists predicted, but it puts constraints on the identity of the heat sources in the core that keep the internal dynamo running to maintain this magnetic field.
