Mainstreamin’ the Matrix

Previously, I wrote,

There is no reason to think something as complex as the eukaryotic cell, or the metazoan body plan, would have emerged without oxygen.

and

In other words, the blind watchmaker was not able to cobble some metazoan-like life forms without sufficient oxygen, even though there was almost a billion years of trial and error. Apparently, there are not lots of ways to string together something like a metazoan. As it stands, it is quite reasonable to propose that the blind watchmaker had needs – it needed a eukaryotic cell plan and it needed oxygen (a biological output) to generate metazoa.

Today we read:

Another strategy that physicist Werner von Bloh at the Potsdam Institute for Climate Impact Research in Germany and his colleagues suggest is to focus on the zones around stars where photosynthesis might be possible, since nearly all life on Earth depends on it one way or another for energy.

Although primitive life can exist without photosynthesis, the researchers argue it would be necessary for more complex multi-cellular organisms to emerge. This is because the main source for oxygen on Earth comes from photosynthetic life, and oxygen is thought to be necessary for multi-cellular life to arise.

There ya go.  There are two lessons we can draw from this.

First, there is just another indicator that my views are both reasonable and plausible.  For how does

?

Second, this is another example where the non-teleological perspective is essentially useless.  For the non-teleologist, there are millions of possible ways to evolve metazoan-like creatures without oxygen.  And for the non-teleologist, there is no reason to think the emergence of metazoan-like creatures would be any more or any less likely with oxygen.  The logic of the non-teleologist would have us dismiss the strategy that physicist Werner von Bloh at the Potsdam Institute for Climate Impact Research in Germany and his colleagues as wishful thinking.

One response to “Mainstreamin’ the Matrix

  1. If oxygen is a biological output then where did the oxygen that produced the earth’s water, come from?

    As for “needs”, geez- the blind watchmaker needed water, a sun powerful enough to warm a planet, plate tectonics, magnetic field, large stabilizing moon- a whole list of things.
