The hawk has clarity, but less fidelity
What are you using that word to mean?
The input device of the hawk; eyes, have a high level of clarity. However, as these optical signals impinge upon its memory for processing, the processing has less fidelity, allowing his actions to be more targeted, without distraction by too much detail. He will not get bogged down in the details of the rabbits fur, even if his eyes can see this, since this level of processing fidelity is not needed for his instinctive goal; catch a rabbit.
Picture if the hawk was conscious of more detail. The first time he catches a rabbit, it has black and white spots. With too much fidelity in memory and processing he may need to hunt, only rabbits with black and white spots. This would not be very efficient.
On the other hand, with less conscious fidelity, that much detail is irrelevant, allowing him to catch any rabbit. The hawk can see this detail with his eyes, but this is not processed as relevant; less fidelity in his instinctive data processing is better. Humans are more quirky due to more fidelity, that so tiny details seem more relevant.
allow the surface water to go beyond itself
In pure water, water molecules will hydrogen bond with each other and can form extended 3-D structures. Water can form four hydrogen bonds with other water, and in some ways can do with secondary bonding, what carbon does with primary bonding. Both can form four bonds. However, in pure water there is a limit to the size and duration for such extended 3-D water structures, due to changes in the hydrogen bonding switches from polar to covalent and vice versa; pH affect, etc. Water is more fluid than carbon based molecules.
If we look at an enzyme, the final surface of an enzyme is what is left after the rest of the enzyme has been packed properly, to minimize the bulk/local water's excess free energy. Larger scale 3-D water configurations can from on these final enzyme surfaces.
Keeping the enzyme packed is important to the water's free energy needs. The surface layer of water, on the enzyme's surface, is firmly rooted in the larger picture of things; bulk water stability. This foundation of necessity, is a platform for water to form extended structuring to further stabilize the bigger picture; cooperatives. These structures are more stable and durable than the similar things in pure water, since these water structures, beyond the enzymes, serves a free energy purpose. Enzymes, in turn, can share this free energy if they try to unpack such as via a boost from ATP.
In terms of natural selection at the nanoscale, not all randomly made protein polymers can be packed to the stability of enzymes. If we started with a random generation of protein, using very poor template processes, enzymes would stand out as stabilizing to the water. Eventually the active enzymes take over the area, since they are better for the needs of water and can help the water clean out the trash. Better template processes would also benefit the water; less high free energy residuals. Water was the continuous phase from the beginning and selected things that benefit itself. The result is nothing in life can work without water.
Other solvents would select other options since their free energy needs are different. Alcohols would not choose DNA and RNA. They would need a different template design. These do not work properly in alcohols. They are fine in water.
