I love seeing people learn for the first time just how mind-meltingly vast and ancient the arthropods are.
Grasshoppers as a group are around 250 millions years old. To put that in perspective, the first dinosaurs showed up 230 million years ago. Grass is a relative youngster and has only been around for an estimated 66 million years.
So, yes, dinosaurs are also older than grass.
What were grasshoppers (and herbivorous dinosaurs) eating before there was grass to hop on? Get ready for a very not-exciting answer; they were just eating other older plants that were not grass. Plants first took to land around 700 million years ago.
Luckily grasshoppers are not particularly picky about what they will put in their mouth-holes. Some are perfectly happy to dine on meat when it’s available, even the meat of other grasshoppers. The evolutionary pitch for grasshoppers was basically “make a very hungry wood-chipper and then give it legs to throw itself at food”.
Nowadays most grasshopper species do have a preference for grass though, so this reaction is pretty accurate:
Convergent evolution is wild, bc like, crabs keep evolving to look the same but aren’t closely related, nature is just like: BIG MEATY CLAWS, little legs, pincers, head, tiny eyes, let’s do it again!
and trees look the same but oak trees are more closely related to rose bushes than they are pine trees, fucked up
nature just likes these damns shapes:
but on the other hand, mammals flying with powered flight?? That shit only happened ONCE and it had to do some janky shit to get there, especially with bat immune systems
likebat’s immune systems are HYPER-POWERED as well as repress most of their inflammatory reactions because in order to fly they needed a bonkers-high metabolic rate which unfortunately also create waste products from the process called “free radicals” that damage cells
however, despite these free radicals they manage to live up to FORTY YEARS, which is super long for a species their size, because their immune system are basically always ON and in an anti-viral state that make them incubators for disease due to warfare between their jacked immune systems and disease
bats are so gdamn weird, I love them, no other mammal has been able to copy off their homework and accomplish the same shape, and for that they are the anti-crab of the natural world, God bless
It really worked out for them too, like it’s a hell of a lane and they have it all to themselves, so they’ve really filled their niche. There are more bats than almost any other kind of mammal. Like, there are a higher number of individual bats, but also the most KINDS of bat.
For example there are about 30 million white-tailed deer alive in the world, whereas there are 15 million Mexican free-tailed bats living in ONE single colony in Texas. But also, there are about 43 species of deer on the whole planet, 38 species of feline, 34 species of canine… and about 1,300 species of bat.
It is estimated that one out of every five living mammals on Earth is a bat, or, to put it another way, if you took every single mammal on the planet and counted them as individuals, 20% of those animals would be some kind of bat.
