comment Is there a timeline for the frequency of evolution of any species?
If not X, then it's most probable derivative. Homo Habilis, Homo Rudolfensis ... so on.

comment How does one maintain balance sleepwalking?
@AlexStone: Agreed. But the floor is not a plain surface. There're various pieces of furniture on it. Perhaps even a step between one room, and another

Curious: If haemocyanin were to replace haemoglobin in a human body, would the person survive?

Clarified to indicate question is not merely about the icefish.

comment What difference does it make in the organism's physiology/metabolism whether oxygen binds reversibly or not?
@AlanBoyd: The answer in the linked question indicates that species the binding is not reversible in Icefish; perhaps other species too. I'm curious about the nature of oxygen binding (reversible or otherwise) does it improve the ability of blood to deliver oxygen/nutrients and in turn what effect that has on the organism's physiology. Could it have evolved to enable the creature to survive adverse environment - as in the case of ice-fish?

comment Can Bioluminescence drive photosynthesis?
@shigeta: (+: I did expect it to be unbalanced. Off-topic, the depth of these inter/co-dependent networks in nature make one revere that nature developed so. Imagine the number of broken branches of evolution & mutation that must have occurred to develop to our present day ....

comment Can Bioluminescence drive photosynthesis?
Don't laugh. I forgot why I didn't want to expose the algae to sunlight ... To answer the second question - burn it!

comment What does self-preservation stem from?
I would argue procreation is a side-effect ...
