For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!
That or my recent addiction to correcting people when they use “less” when they should use “fewer”
DNA gives us insight into ancestry that has no parallel in astronomy. When we finally sequence a creature, we pretty much know right on the tree where it goes and stupid fucking crabs and everything that look like them can all get placed in their proper relations when previously purely dissection and observation misled those taxonomy pioneers.
you can’t have that kind of bait and switch on celestial objects because what we see is what we see.
The reason that Pluto was smaller than predicted was the fact that the mass calculations assumed a single central object when the perturbations were made by the PLANET/moon system. That doesn’t change the fact that it has enough mass to deform into a spheroid and orbits within 20% of the orbital plane.
DNA has made it a lot easier to deterimine ancestry yes. But most of of taxonomy has been created on nothing but observational data.
For example, rabbits, hares, and pika used to be classed as Rodentia until they were placed in their own order, Lagomorpha, in 1912.
Also, the other dwarf planets were considered large asteroids until they were upgraded to dwarf planet status… so if you wanna be upset, you should be upset pluto isnt an asteroid.
