> dhw: No one has found an explanation for the gap. But a radical change in the environment (increase in oxygen?) might provide a massive range of new possibilities. Hence a massive surge in inventiveness. -Right. A 'massive surge'. Oxygen did rise, but did it have some parallel effects? That is poor statistics: in the 1940's it was shown that the rise in Coca Cola use exactly paralleled polio's rise, raising some stupid alarms. Developing brains from nothing, nada, requires more than 'inventiveness', a squishy term if ever.-> DAVID: We don't know this is the method of a 'guided evolution'. It is one of many possibilities.

> dhw: Apart from the 3.8-billion-year computer programme and the divine dabble (which is bringing you closer and closer to creationism), please tell us some of these many other possibilities you can envisage.-Yes, I accept created evolution. Easy step once one realizes that this universe requires planning by an intelligent source.
