Comment on Chicken vs Egg
AnonStoleMyPants@sopuli.xyz 5 months agoNo, the shicken egg was a shicken egg even prior to you eating it. The act of giving it a name is irrelevant. The proto-chicken could’ve lain a hundred eggs, each becoming a new “chicken”. If 99 of them die off and are never born then that does not mean they didn’t exist. It just means they did not exist in a way where we could’ve given them a name.

The distinction between “chicken” and “egg” is biologically irrelevant: they both refer to the same organism. The terms are descriptive, not prescriptive. The organism will progress the same way, regardless of what we decide to say about it.
The chicken/egg argument is purely one of semantics. “Giving it a name” isn’t just relevant to the discussion, it is the only factor relevant to the discussion.
The way you would have us describe the egg prevents us from accurately and consistently defining an egg. An egg laid by a chicken could mature into a new species, and by your arguments, should be described as an egg of that new species.
This creates a linguistic uncertainty in any case where the egg’s potential is not and cannot be known. Is there a Shicken egg among the dozen you bought? A Blargleblat egg? Do you have the eggs of a dozen new evolutions with a common chicken ancestor? You cannot say with certainty.
However, if we describe the egg as the product of the creature that laid it, we have no such uncertainty. If we describe it as the possession of the offspring within it, we have no such uncertainty. The uncertainty only arises when we try to define it by an unknowable condition that may or may not occur.

But that same argument works the other way too, no? If you define a chicken egg as an egg that came from a chicken, then if you have a dozen of eggs you cannot know whether they’re chicken eggs or whatever eggs unless you know specifically a chicken laid them. Even if you take a dna test of it and it comes back as “a chicken”, you cannot know whether it is in fact a chicken egg.
In the other definition you are capable of determining whether the egg is in fact a chicken egg by its contents.

Correct, but that is information that can be known, whether it is actually known or not. When you eat a bird egg, you can know what bird it came from. You cannot know what bird it would have become, specifically because you prevented it from ever becoming that bird.
You could speculate that it could have become a new species, based on the genetics within the egg. But, even if you didn’t eat it, it could have failed to mature for any number of reasons. It might have become a new species of bird; it might have become a rotten egg.
The aphorism “Don’t count your chickens before they are hatched” specifically warns us against considering the future possibilities of the egg.

I just don’t get why you’re so hung up on the potentiality of an unhatched egg when that has nothing to do with the scenario. The egg in the scenario hatches and it has a chicken in it. That’s the whole point of the scenario.

OK, think of it like this instead. Obviously fuck accuracy, for ease we’ll call them cavepeople. Two different cavepeople that are genetically distinct from humans have sex, resulting in a genetically human fetus. That doesn’t change the cavempeople into humans, they’re still genetically different. It’s a caveperson’s fetus, but it’s a human fetus. Same thing with the egg. Genetically, the thing inside is a chicken and, genetically, the things that made the egg are not.

not to dig this hole any deeper, but the defining characteristics of a chicken aren’t like, easily identifiable. we can build a hypothetical in which two proto-chickens are genetically capable of producing offspring that is “chicken”, but that’s kinda rube-goldbergesque, there must have been some extremely specific series of genetic coincidences required to produce something chicken enough to be a “chicken” in that scenario. genetics, and evolution more generally, tends to be more complex. the specific genetic markers that distinguish chicken from non-chicken, if we say they exist, are probably not in and of themselves what makes a chicken, because single gene changes don’t usually make creatures incapable of interbreeding with their parents’ species, and that’s a defining feature of the taxonomic category “chicken” belongs in.
like, if we grant that the chicken came from a proto-chicken egg, because the chicken has a special chicken gene, its really really likely that the next generation of “chickens” came from our progenitor chicken mating with a proto-chicken. taxonomically, that means that proto-chickens are chickens, because species is commonly defined by the ability to produce fertile offspring (eggs). so for every step in the process towards chicken-ness, we can’t really say that the egg came first in a taxonomical sense, because the first member of the species of “chicken” (as defined by whatever genetic marker we claim indicates chicken-ness) was almost certainly able to reproduce with things that didn’t have that genetic marker!
maybe there’s some other sense in which the chicken and the egg can be discretely separated, but if we are talking about species, taxonomically, anything that can lay eggs to make fertile chickens must be a chicken by definition, barring some really weird edge cases that probably didn’t happen.
fun fact: plants can do the weird edge case, and do it quite often. plants can duplicate their chromosomes without catastrophic consequences, unlike animals, and they can reproduce without sex with another individual, so a plant can produce offspring that aren’t fertile with their parent species, and can reproduce independently (called polyploidy). so a seed can come before the grass (as with some kinds of wheat, and many other plants). this can also happen in reverse, where a polyploidal offspring can start reproducing with a species it couldn’t before!

Yeah, we were necessarily ignoring the obvious evolutionary issues inherent in the chicken-and-egg scenario, since it very clearly was not one egg-laying instance that created a new species. I know I made reference to as much somewhere in the thread, it seemed like a waste of time to restate it every comment. I’m fairly certain we were on the same page about that. Cool wall though!
