1+1=2 does not refer to any manipulations with the things, 1 and 1. It refers to counting things. If you count some things and find that there is 1 of them, count some other things and find that there is 1 of them, then if you count all of these things you find that there are 2 of them. This is what 1+1=2 says.

I think it is very difficult to know why people do what they do. Their personality, development, and environment affect their behavior, and then they come up with a narrative to explain and justify it, sometimes, to themselves and to others. Let me ask you: why do you want to know the answer to this question?

Sour grapes, again (the second time today; the other one referred to math.)

Me neither. Pandas and tumbleweed.

Also, most fish, I think, have many bones and/or cartilage protecting all organs. These don't cost much in the water as long as they are attached flexibly.

OK, I'll try. The goal of humanity should be to relax.

I think that data science is a major shift.

Curiously, I keep reading the same about biology, how it is monopolized by ideas like evolution and how there are both serious problems and promising alternatives to these theories, but they're suppressed by academic politics.

To be or not to be?

Oh, sour grapes!

No, because it's homework.

Is this a right forum?

What do you think about rolling pandas? Looks like a mode of transportation for them: Rolling Is A Specialty For Pandas | iPanda - Bing video

Glad I've asked. Learned a new word, phatic.

Perhaps, but what does it mean? I honestly don't understand semantics of this word combination. For example, I don't know if there's anything wrong with smelling with my mind's nose what my spleen feels. And if there's nothing wrong with it, can I smell nothing but other spleens?

I assume that 0 and 1 in OP don't stay for arithmetic numbers, but rather represent logical values, which by usual convention are: 0 for FALSE and 1 for TRUE.

It can be true since 1 -> 0 = 0.

One way, in theory, is if the group whom you benefit consists of your close relatives with whom you share genes. By benefiting them you help them to propagate their genes, some of which are your genes. Thus, you help them to propagate your genes including the genes responsible for this trait.

It did. Example: tortoise.

IOW, I would say that a signal is sent if something evolved because it helps others. But, Accordingly, I say that signal is not sent.
