Telescope Reviews: origin of life

Maybe we can define 'objective' when the 'entirety of the information is transfered'. That should be the case for a photon but not for a human, as when we observe a mushroom, the entirety of the information contained in the mushroom is not transfered to the human observer, and this amount of information varies from observer to observer, therefore the non-objectvity.
In information theory the total amount of information is dependant of the probability of observing one particular bit of information (an the log of the number of all the items of information). For most untrained observers, the most likely element of information is the shape and the color (of the mushroom for example). But let's imagine the shapes and colors of different mushroom species vary very little, then the most likely item of information that untrained observers retrieve from observing mushrooms, when trying to identify their species and edibility, actually contains very little information regarding their toxicity. Only trained experts, able to retrieve small differences, unlikely to be perceived by untrained observers, might be able to identify the correct species. So who will decide who has retrieved the most information? Natural Selection, since the poisonous mushrooms have killed all the non-experts.

Natural Selection acts as a filter of 'objectivity', which, combined with 'Evolution' (=constant measurement of the environment), provides a darwinian non-casusal mechanism to explain the increase in complexity during evolution.
What's puzzling is indeed that human observers are part of the Universe, so the universe is observing himself, like a photon going to point A to point A. That's, IMO, when Evolution starts to depart from pure non causal darwinism to something else. Some may argue that an 'infinitely small part of universe' is not 'the Universe' but we are a growing part, at some point it will make little difference.
If you believe in the concept of Noospshere,
http://en.wikipedia.org/wiki/Noosphere
the Noosphere is expending. The definition in Wikipedia restrains the Noosphere to human consciousness but in my personnal opinion, all living creature are concerned. While watching a show on dolphins, i thought that in the next 10 million years it is unlikely that they will grow arms and legs since they are already so well adapted to their environment, the only thing left for them to evolve is to increase their sphere of consciousness. Maybe ants will do that too, maybe mushrooms too in a billion years from now.
