    Efficiency is making the same structure work for dual purposes.....like garbage disposal + procreation.

    I don't think you procreate if you stick it up the garbage disposal though.

    Garbage comes in different states of matter...

    You know what the alternatives are, right? either we have two mouths, or we speak with our nostrils and the silent, gaping hole below only unhinges for the consumption of organic matter.

    Maybe we should get an update on the human body. For example, permanently remove Body Hair, since it no longer serves any function.

    It does? Look at your arms when you're cold, you'll see all your tiny hairs are standing to help prevent the body from losing too much heat.

    It's either cold enough that I'm gonna die or it's not. Those tiny hairs aren't going to save me in a situation where it would matter.

    "It's either cold enough that I'm gonna die or it's not. Not sitting on the cold floor isn't going to save me in a situation where it would matter."

    Until you remember that your body needs energy to heat your body, and needs less energy when you lose less, having more spare energy for other things like your immune system.

    Yes but how much heat are those hairs actually saving? In real terms I doubt it's a number that's meaningful at all. Like if you had 2 clones and one had their hair shaved and one didn't, I'm not convinced you could even measure the difference without super sensitive tools and even then it would be a fraction of a degree.

    I also doubt there's any situation where, all else being equal, one would survive and one wouldn't purely on the basis of having those hairs.

    Sounds like we should optimize that.

    Thinking about how smell might have developed is kind of cool. Some mutation allowing cells to detect smell (something modern science is kind of puzzled by) then just sending those signals to the brain and saying, you figure it out. I'd bet there is some other property of matter that exists that we have no ability to detect.

    Isn't smell just particulate matter hitting receptors not dissimilar to how taste receptors send taste signals to the brain? I thought science had this stuff nailed down now?

    That's what they theorize. How do you prove it?

    Science shit?

    I dont know....but I wouldn't say that's a good reason to doubt it, for example I don't know how they proved black holes exist but they seem pretty confident.

    Ok, if it's just particles how does it distinguish the particles on a molecular level. This is important shit. The closest science can do is gas chromatography and that's an instrument which exists in any reputable lab. Also, using gas chromatography for this a far cry from the simple function of our sense of smell which can distinguish scents just by simply introducing a fragrence.

    Maybe I'm misreading your tone, but I'm not trying to argue with you - I'm genuinely curious about this and if you have superior knowledge I'm open!

    My understanding from a quick skim of Wikipedia citations suggests we understand what's involved (particles and receptors) but the actual mechanism around encoding of signals seems to be theory.

    We also can't teach a computer to think, but we still have quite a good idea of how it works.

    I believe the receptor cell responds to a particular part of the molecule in question. Artificial flavourings and scents have identical (or similar enough) parts to trigger the same response, but are otherwise different molecules.
