monotremes


believe victims

1,059 views

it's two in the morning and i'm thinking about monotremes. like, dude, they seem so weird, but now that i think about it, they actually make complete sense with our current understanding of mammal evolutionary history. like, with our synapsid ancestors being rather reptile-like and egg-laying, it stands to reason that at one point mammals could have had fur and milk but still laid eggs.

 

of course, that there are still monotremes today works just fine with that understanding; evolution is a tree, not a flight of stairs. some monotremes went on to become marsupials, some of which went on to become placental mammals, but a small group of monotremes just stuck to the monotreme thing, because hey, they had no reason to change

 

and that's why platypus are so weird.

 

well, one reason why. still doesn't explain the venom.

 

i need to sleep.
