GABA ghoul posted:Why are the testicles the only two organs in the body that need a different temperature? Skimming the Internet there seems to be two hypotheses but no conclusion: - Early mammals had lower body temperature, and at some point there was a benefit to increasing it (probably because it allows or is a side effect of more bursty movement, like sprinting), but something about how sperm develops didn't work quite as well when warmer. Thus having a testicle cooling system became beneficial - and then it just got stuck because evolving away from it requires some very specific changes in an area where halfway measures disappear from the family trees really quickly, for nonzero but not huge benefits. - Sperm are way more active at body temperature, so developing at a cooler temperature means they save their energy reserves until they warm up inside a vagina.

i dont think an animal perceiving zero -- or 'nothing' -- is the same thing as 'using' zero mathematically but im sure this is a very fun article for math/bee nerds

It's semantical I suppose. Voyagers crossed the Heliosphere. But the solar system can certainly be defined as to the boundary of the Oort Cloud, and it will take the probes thousands of years to cross that.

...! posted:NASA themselves say that both Voyagers are now interstellar It's still debatable, but I agree NASA does say that. Only because they are defining (in this specific case) interstellar as "being effected by forces outside the sun", as opposed to within the heliosphere, where the local solar wind blocks out interstellar winds. Here's a NASA FAQ on the subject of the Voyagers. https://voyager.jpl.nasa.gov/frequently-asked-questions/ A better definition of the solar system, IMO, is the Oort Cloud, AKA the gravitational boundary of the Sun's influence.

From that FAQ:quote:Sometimes, it is written that Voyager and Pioneers 10 and 11 have exited the solar system. Though all of these spacecraft have gone beyond all the planets of the solar system, they have not exited the solar system, based on the scientific definition. To leave the solar system, they need to pass beyond the Oort Cloud. Voyager 1 was the first-ever object to reach interstellar space on August 25, 2012 when it passed beyond the sun’s realm of plasma influence (the heliosphere) and it is the most distant human-made object. But it will take about 300 years for Voyager 1 to reach the inner edge of the Oort Cloud and possibly about 30,000 years to fly beyond it. Voyager 2 has not yet reached interstellar space or exited the heliosphere (bubble of solar plasma). Pioneer 10 and 11 are no longer transmitting science data back to Earth.

Vampire Panties posted:I read somewhere that its theorized that mammals developed a higher body temperature to deal with parasites. Sure that sounds just as plausible. Either way, the ratchet mechanism suggested is: - Low body temp, internal testicles, all is fine - Something makes higher body temperature so beneficial that it wins out even with an accompanying reduction in sperm quality - An external scrotum can develop gradually and having better sperm is a clear advantage, so that takes over - Now that you are back to 100% sperm quality again, moving the testicles inside would be an immediate handicap. Evolving sperm that can develop at a higher temperature first would open for it, but there's no real pressure for that to happen (with exceptions, I'm sure). Not that it's universal. Elephants apparently have their testicles safely inside their bodies.

GolfHole posted:can cold-blooded animals digest cooked food efficiently Is there a reason they couldn't? Cooking food makes it much easier for us to digest because putting that energy into the food in the form of fire is energy we don't have to put in breaking it down. I'm no biologist. Is there any reason why it would be different for a cold blooded animal?

Stoatbringer posted:If humans come from monkies then why are there still monkies? the same reason butterflies come from caterpillars but there are still caterpillars once a year monkeys weave themselves into a cocoon for a couple of months and then at the end of that period they hatch out as a human. so any monkeys you see around are just humans that haven't undergone that process yet, but they probably will next year.
