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
like bat’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
In like, seven years we’re gonna see a question on some bio-exam: 1. Bats are the opposites of Crabs. EXPLAIN:
