They have to do with capacity to survive and thrive. But people who can't do that, are not stopped from existing and therefore breeding.
The only selection going on is that some people are more likely to find a mate. But no one is having lots of kids and most people can find someone to have kids with

More specifically, fittest is defined as those individuals who successfully produce the next generation. Once that's done, their death has no impact on evolution.

I think you meant "Chloric acid", and no, the gene pool can do quite well without it.

Not sure. In Spanish we have "ácido clórico" (HClO3) and "ácido Clorhídrico" (HCl)
I meant the second one. If I got the translation wrong, then I stand corrected.

I was wrong, too. In English, HCl is Hydrochloric Acid. 
HClO3 is Chloric Acid.

Interesting. I did a check in google and my version was identified / suggested in the search bar, I supposed it was right.
Clicking on search, there is a high number of site titles with you option.
But I found this:
chlorhydric acid[^]
Looks like "Hydrochloric acid" is the official name (and the most extended one) but "chlorhydric acid" (I wrote it wrongly in the previous message) is accepted as a synonym too.

Not to worry . . . Chloric acid is extremely unstable and will likely blow the owner to itty bitty pieces almost immediately. It's sister, Perchloric acid (HCLO4 is stable enough to keep in bottles - also highly explosive on its own. Something I've actually worked with. It makes an insoluble potassium salt (rather rare) and is a very strong oxidizing acid - used to "fume" things, i.e., break them down chemically by boiling them in the acid. If something organic falls in during this process, well, it tends to crumble things when it goes off with astounding violence. Salts of both of these are common fireworks ingredients. Shock sensitive, although you usually need a hammer (unless mixed with red phosphorus as in matches).
Hydrochloric acid (HCL)? Who's got a stomach to handle that? Actually, all of us - diluted quite a bit it's the acid in your stomach used for digestion. Concentrated (=37% 12.0 molar) is how it's sold. One of the strongest acids known - but I'm sorry to say it doesn't work like acid in the movies. Not at all. Acid strength is based upon degree of ionization in solution and this stuff is about 100% ionized.
Way more than you need to know but it brought back my very early youth, when I used to make my own fireworks.

OK. Any complaints about these lessons is "on you !"
Stomach protects itself - prostaglandin 1 if I recall correctly. Without it, you would slowly digest your own stomach. Many NSAID's (like aspirin, but NOT acetaminophen) have a side effect of suppressing your prostaglandins and that's how chronic use can end up giving you ulcers. It's not the aspirin, an extremely weak acid, that does the damage (at least not directly).
Although it doesn't have to be water, acid strength is typically considered how completely the acid ionizes in water. That is, HCL become H+ and Cl- when in aqueous solution. There is no HCL left. This is facilitated by water being very polar. Water is a bent molecule (CO2 is straight). Because it is bent, the local charges are asymmetric on the molecule even though it's net neutral. Like a magnet, in a way, it has poles (hence "polar"). The O in H2O holds the more negative charge, the H's, the more positive charge. They can thus "solvate" ionic species and stabilize their charge. It is for this same reason that salt (NaCl) dissolves in water and is only in existence as Na+ and Cl-. Solvation is a pretty powerful force as it has to, in the case of salt, break up the the salt crystal lattice. (At this point, it gets more complicated as we would talk about Gibbs vs Helmholtz free Energies and Entropy). Anyway, it's for this same reason oil and water don't mix: the water molecules are attracted to one another rather strongly and will not let the oil molecules intervene. Intermediate substances, such as alcohols are polar. Small molecules, such as methanol, ethanol, and propanol are polar enough where entropy will make the totally miscible with water. The randomization of the molecules overcomes the mutual attraction. Longer chain alcohols are not totally miscible (but are soluble) with water, less and less so as the organic part dominates its properties. Soap . . . a magic substance (look up micelles) ! Note, back to the original topic, if you were to dissolve HCL in something totally non-polar, like hexane, then it would not be ionized.
Other definitions of acid in other contexts:
Bronsted Acid: Based upon the ability of a substance to "donate" or "accept" protons (H+)
Lewis Acid: Based upon the substance's ability to donate or accept electrons
There are other definitions for other contexts - these two are often relevant in Organic chemistry.
Anyway, that's more than enough for now. And then some
"solvate" implies they surround the charged particle (ion) and diffuse it's charge and thus stabilize it.

Actually, just morons looking for someone else to blame their failure upon.
As their deity would describe them: Losers!
But really, who else would losers follow, and who else would depend upon losers for a following? See, the world is amazingly orderly in its design.

I understand it feels good to demean. There has been so much of it lately.
As Gandhi said, anger and intolerance are the enemies of correct understanding. Good luck with your path.

My path is not that of Gandhi - that was HIS path.
Mine is to try, however hard, to see the humor in our existence rather than descend into it's pathos.
Let me give you another philosopher's thoughts - not quite the same flavor yet real it encompasses Gandhi and Nietzsche, Vonnegut and Lennon:
"I'm the one that has to die when it's my time to die" - Jimi Hendrix

Exactly. My point was that your path is NOT that of Gandhi. That's OK. Everyone chooses for themselves.
I share your point of view on humor in our existence.
So did George Carlin. I wish he was around to provide some commentary on our current world. Some of his thoughts were timeless though.

Talking of birds and flocks ...
May I recommend Charlotte Hemelrijk: The collective motion of flocks of birds[^] - a 30 minute 'Science & Cocktails' talk about the stepwise development of a simulation model of the movements of a flock of starlings. If I were teaching simulation to Comp.Sci students, I would certainly refer the students to this presentation, as an excellent example of how to model a physical phenomenon!
The Science & Cocktails presentations are great!
(The family name of the speaker seems appropriate when she talks about flocks of starlings  )
