Potassium channels in the action potential – when do they close?
Hello, I'm trying to figure out when the K+ channels close again after repolarization, since they close (significantly) more slowly than the Na+ channels. I've now found out that the Na+ channels are open for less than 1 ms, but the K+ channels say something different. I read 10 ms in one case, and 1-2…
My budgie is sick!?
ByLucia27
Hello, I'm new here but I urgently need help! My budgie (Lucky) has been sick for about 4-5 days. She has diarrhea (light green, runny stools ) and is gagging a lot – often with mucus, sometimes nothing comes out at all. She is also extremely tired and puffed up all the time. I've also…
Why isn't my budgie moving?
He just sits there and chills, he doesn't do anything, he's not even afraid anymore. Two weeks ago he was afraid of my hand, but not now. At first I thought he had gone blind, but that's not him, because I went to the vet on Monday and he said that he doesn't have anything,…
Will humans lose their body hair over the course of their evolution?
Will we continue to lose our fur, as has been happening over the millennia? Our hair used to protect us primarily from the cold, but with our clothing, this is no longer necessary. So, will our hair die if we can continue to populate this planet for thousands more years?
The best way not only to understand the evolutionary development of the bird’s beaks, but to understand the evolution as a whole is this:

All animals have no multi-part cutlery!
Birds have special beaks for the food they can get!
Some also use their foot claw as support .
Beak: The shape depends on the food: picking up or cracking cores -> thick short strong snails. Insects from holes pick -> pint-like slender beaks. Plants -> spoon-like or sense-like scabs.
Feet: Eat from water -> Floating feet. AUf trees running around -> Climbing feet.
Generally: the beak is optimised to eat food, the feet are optimized to come to food (or to keep it firmly as in some parrots).
