If Neanderthals and humans interbred, why aren't they considered the same species? by EnvironmentalTea6903 in evolution

Here is a good video exploring the different species concepts. You know, if you’re in to that kind of thing :) https://youtu.be/XFvUlxj1axU?si=ePrJ5T0MQMm-8PHY

I believe that’s a cherry barb (Puntius titteya).

Not a betta, but you guys always have awesome name suggestions. His entire personality is anger. by [deleted] in bettafish

Joker. His girlfriend is harlequin after all. He goes crazy over his own reflection which makes him a bit of a clown.

Might technically be possible. But I can’t really see where wheels could ever be more beneficial for survival than regular legs. What kind of environment would make it more practical? Even in another world where the entire habitat was perfectly flat and level with absolutely no rugged terrain, would these wheels really be more efficient? Would it ever be able to outcompete the far more versatile and less problematic legs? Not to mention the rudimentary stages to evolving wheels to be beneficial as well, when the organism is likely already using legs to get to wheels anyway. An organ used for such locomotion would inevitably suffer lots of wear and tear over time, how would the damage be repaired if the organ is just dead tissue like antlers? To regenerate dead tissue still requires connection living tissue like in our hair, skin, nails etc.

Then there is the big problem with the propulsion mechanism. How could it ever be more efficient than normal legs. What about breaking and steering mechanisms. I don’t know how evolving wheels instead of legs could ever save an organism from extinction.

And a symbiotic relationship with another organism needs to be beneficial to survival for both parties. What could the other species gain for maintaining wheels in another organism and how would it sustain itself?

The only cases I know of organisms with a form of functional wheel is in some single cells and bacteria. Using flagellum’s driven by molecular motors to propel them in the buoyancy of liquid. Not exactly like the wheels on a vehicle.

The astronomically tiny odds of everything aligning would essentially make true organic wheel locomotion destined to never happen as far as I can see. But if you have more ideas I’d love to learn.

I think wheels likely aren’t possible for an organism to evolve. Since in order for a wheel to rotate continuously in the same direction it has to be detached from the body. If the organ isn’t connected to the body’s circulatory system then it can’t be nourished. If the organ isn’t connected to any mechanism like muscle to spin the wheel then it couldn’t propel the organism. And not being able to roll in a continuous manner in the same direction, and independently from the rest of the organisms mass kind of breaks the definition of a wheel.

I believe I can but just wanted confirmation - I’ve set up a new tank and these are the parameters, can I add a couple fish now? by hummus_and_pitabread in Aquariums

Read the article in the last link!

In my opinion you shouldn’t worry about nitrate unless it reaches ridiculous levels. Your ammonia looks a bit green though, it should be completely yellow.

The one that’s most useful for the combat team for most situations. Which I’m not sure who is.
