comment Is there an “Adam and Eve” for each new trait during (not just human) evolution?
@IlyaMelamed - So you're talking about different ways traits evolve. Convergent, divergent, etc. If you can find a way to make that clear in your question, then I'd take away my Duplicate vote since there doesn't seem to be a good question covering evolution of traits.

comment Is there an “Adam and Eve” for each new trait during (not just human) evolution?
I think I'm with Michael Kuhn. The concepts between the questions are very close. Ultimately the answer is 'Yes' - there's an "Adam and Eve" or "Parent" to every extant species today, but it's probably not like you'd expect. They were simply able to pass on their trait more successfully than others.

comment What is the advantage of circular genomes for bacteria and linear genomes for other organisms?
@Bitwise - I'm sure there are examples of linear chromosomes in Bacteria/Archea. I don't think there's an explicit need for it to be condensed, but its ability to be condensed is very useful to the cell. B/A don't sexually reproduce, may not have a nucleus smaller than the cell to stuff all the DNA in, and may not need to shut down large swathes of genes they are forced to keep around (like women do with many genes on X-chromosomes). So I'd say not necessary, but very useful.

comment What is the advantage of circular genomes for bacteria and linear genomes for other organisms?
@Bitwise - Speed is definitely part of it. It takes time to condense all of a linear genome into Chromatin. A circular genome isn't necessarily easier to replicate (the proteins involved operate at about the same speeds if I remember correctly), but when your species depends upon a very, very fast generation time then a genome that you don't have to pack is a huge advantage.

comment Simple diffusion of lipid-soluble molecules through phospholipid bilayer — does anything get “stuck” in transit?
I'd say it's certainly possible, but I doubt it would be for very long. I cannot think of a single concentration gradient that's at equilibrium for every long with respect to cells. They are always quickly restored to some imbalance, so as soon as the cell starts to restore the imbalance, the molecule/atom would be urged to choose a side.
