Not at all. A gene is a physical replicator that is passed down through (sexual) reproduction. A meme is a mental replicator that is learned.
Right, so what I'm saying is that your points regarding language are both quibbles with respect to its being a meme or not.
The ability to use language is clearly not a "mental replicator that is learned".
Yes, there are significant differences between language and shivering and blinking, but they are all biological functions, and none of them are memes because biological functions are not memes.
Puberty is probably a better analogy. It's a hard-wired developmental process. And while there are certainly many memes surrounding puberty, puberty itself is not a meme, it's a biological mandate.
Ditto language. It is not a meme. It is something that all normal human bodies do because they are programmed to do it.
It's certainly true that the particular language one learns is dependent on environment, and this makes it different in an important respect from puberty, but that doesn't change the fact that acquiring and using language is biologically pre-programmed.
As you know, a baby begins acquiring language well before it can make any use of it. It does so because its brain is wired to pay special attention to language in very particular ways and to set specific parameters and acquire vocabulary.
And as it grows, the child uses language as a matter of course, just as it crawls and walks as a matter of course. This is not learned behavior. Language is no more a meme than walking is.
As for cases like Genie and Victor, they are also quibbles in this context because they only show that the biological process can derail if there's something absent in the environment which the process expects and requires.
If, for example, some necessary protein were absent when expected during fetal development, we can certainly imagine an unfortunate child born without a blink reflex.
No, we learn it. We "develop" pubic hair -- we don't acquire those from the environment. We "learn" language from the environment.
This is actually fairly easy to illustrate with adoptive children; a Chinese newborn adopted by a Norwegian family will "develop" dark hair and eyes according to the children's genes, but will "learn" to speak Norwegian with a completely native accent.
No, we don't
learn it. We develop it, just as we develop hand-eye coordination.
Both require input from the environment, but this is not a problem because the environment (with so few exceptions as to be negligible) always provides adequate input.
The example you give here makes no sense.
The Chinese newborn has genes which determine its hair and eye color, and also has genes which determine that it will learn whatever language is spoken around it. Or whichever languages are spoken around it.
The child will not know (without study) why its hair and eyes are dark. It will also not know how it came to speak Norwegian, or even what the rules of Norwegian grammar are. And yet it will have dark hair and eyes, and it will have acquired Norwegian without a single bit of instruction.
