How do we know none of the fish species never had lungs? Isn't it impossible to define a fish biologically without excluding a whole bunch of land living species?
We probably can't. It's just lungs are more complex than gills and usually evolution goes towards to more complex systems. If you're talking about classification, I wouldn't say impossible. Though I'm not a taxonomist.
Ah, legless lizards. Gotta be one of my favourite genre of scaly bois
it has legs, but just one pair, which is hilarious
I can't tell which way evolution is going
Oh, i miased it from the meme somehow lol OK, only the hind legs makes it even funnier

The site where the screen seems to be captured has a higher res version of the image where the right hind leg is visible.
skinky
Ah, Australia! So, in which weird yet amazing ways will this one kill you?
So, with more evolution, will it lose those legs or will it gain front legs?
Evolve into fins, then gills, then come back to the ocean
Probably not the gills. Once you go lungs you never go back, looking at all those mammals in the ocean.

honestly, it's for it to decide (As a human I'd whisper stay the course, hands are overrated and gave me taxes)
Oh my god, amazing! Skinks are good bois. Happy to have more of them. The name is pretty cool too. Tagalaka slider. Rolls off the tongue.
Wait til you hear about Glass Lizards (and other legless lizards.)
A new one is cool too though!
Skinks are cool but they don't beat the olm
We have those in the south west of UK where I grew up. We call them slowworms.
Lol, we call them blind sneakers? in German
