Absolutely agree. I learn languages by using them, NOT via translation. Moreover, it might be personal issue, but while I easily switch in conversation or when reading between the languages I know, I have a very hard time if I'm asked to translate what was said from one of the languages to another. This requires huge mental effort. It's like when I switch to a language the brain switches to a different mode and there is no direct connection between the modes. BTW, here is the ASL sign you've mentioned: PAST-YOUR-EYES-MILK-[pasteurized-milk]-[pun] - YouTube

One part of the OP that was not addressed yet, I think, is the mention of "infinity ... inconceivable for us." I agree that infinity is a complex notion, but I disagree that it is inconceivable. Though, like in other parts of the OP, it is not clear what they mean.

This "trait" of furless babies might be simply a delay of development of the secondary sexual characteristic. Then, it is not selected one way or another. The one variation it allows for is in duration of the delay until maturity, and this I think in fact varies between populations.

Maybe this very simple computer example will make clear how useless is DNA by itself. Let's take this "DNA" code: 60 00 00 80 A4 00 00 00 60 01 00 84 A4 01 01 00 60 02 00 00 60 03 00 04 60 04 00 00 60 05 00 01 08 00 00 02 20 00 00 03 20 04 04 05 11 20 04 01 and "seed" it somewhere. Nothing meaningful will happen unless it is "seeded" in a very specific place in memory of a very specific computer, in which case a number of zeroes will be written starting at a memory location, where the starting location is given at the memory address 0x80 and the number of zeroes is given at the memory address 0x84.

No. Everybody should be skeptical toward their religion.

The same tendency is inherent in ASL, I think (as little as I know it.) Specifics can be signed but are signed only when necessary.

If they are not electrically insulated from the ground, they discharge via ground. The other questions above would be better answered by better informed people.

In short, "just-so stories."

Respect has to be earned.

How does it apply to, e.g., electron?

Why is it so? Why could not this trait evolve multiple times independently in separate human populations?

Yes. It applies to good electrical conductors. They will eventually discharge via air.

Hence, humans originated on a tropical island.

I live in tropics, and we have rainy season. The rainy season is wet, but certainly not cold. I often sit under a tree and enjoy the sound and the smell of rain.

I understand that the sign 去 is vague. My question is if what they say is as vague as the writing?

Alternatively, they could have two conductors attached, the charges redistributed by induction, and then the conductors detached, one positively and another negatively charged.

Spam, spam, spam, ...

1. Right. 2. Friction, induction, electrolysis, photoconductivity. 3. No. 4. Depends.

As the French language evolves, they could either stop using pronouns, or start using simpler forms of verbs. In Hebrew, for example, children and less educated adults would say, "Were you looking for me?", while a literary form is one word (achipastani?), which contains the verb, the tense, the subject, the object, and the question.

Aren't human babies hairless just as another consequence of being born too soon? Humans are born too soon: impact on pediatric otolaryngology - PubMed (nih.gov)

Russian is like Latin, Italian, and Spanish in this respect, but it needs the pronoun in past tense. While in Hebrew you need the pronoun in present tense and don't need it in past or future. Papiamentu is like English.

I have a question about the timeline. Weren't humans hairless before they first left Eastern Africa? If they were, what was the climate there when the hair was lost? Another question is, does fur give a significant benefit to a child? Does it make a difference in surviving childhood? Considering that human children are very fragile and dependent on adult protection in many respects compared to other mammals.

Interestingly, peoples who started putting on clothes thousands of years ago, East of Mediterranean, have more bodily hair today than peoples who didn't cover their bodies until recently, Australian, African, Amazonian tribes. (My personal observation.)

Honestly, I don't remember.

I see everything having a "notion" of self. For some things it is the only "notion" they have. A rock "knows" itself, and nothing outside itself. When you throw a rock, it "feels" itself being thrown, without a notion of an external agent by which it has been thrown. In animals, during evolution as well as during ontogenesis, this notion of self gets separated from notions of agents which are not itself. That's when a theory of mind starts.
