>be a plant>have an imperative to propagate your species>evolve attractive, colorful berries so that animal frens can eat them and spread your seeds in their droppings>kill or sicken animal fren insteadWhy do these exist?
vary good picture saar i like alot !
>>5155876>never consume uid berries unless you are 100% sure they are safe.>in case of suspected peisoning, immediately call for emergency
>>5155876they do not want the undesirables from enjoying their delectables
>>5155876so the animal only dies a set distance away and the corpse is free fertilizer

>>5155876Having seeds survive the chewing and digestion of mammals is harder than having them survive the swallowing while and digestion of birds and reptiles. So plants without the genetic legacy required to harden their seeds against chewing and mammalian digestion benefit from discouraging mammalian consumption of their fruits.
>>5155876You're getting it backwards, the co-evolution processe in this case goes like this>Be plant>Dev fruits to surround seeds so that when they fall they have fertile soil>Animools eat them>Make them poisonous to defend seeds (which are already full of toxins)>Animools keep eating them and develop resistances>Some plants co-evolve with specific animals as there's positive pressures (wider propagation)It's all very selective case by case, like all herbivores have very specific diets and don't just "eat plants" they eat a bunch they developed resistances/codependency with.
>>5155876These are for the birbs, not for big apes
>>5156179This. It only kills mammals because they destroy the seeds when eating
>>5155876Makes a free envelope of fertilizer out of what eats it.
>>5155876it's too bad because yew berries look like they'd be delicious
>>5156163>Some plants co-evolve with specific animals as there's positive pressures (wider propagation)ok but how do the plants know which creatures to discriminate from, decide "I will make poison to these animals but not those" if they have no eyes
>>5156489Man idk they are berries why don’t you go ask them?
>>5156489>plant makes berries poisonous to mammals but not birds>birds eat the seed and shit it out miles away helping it spread>offspring has mutation that makes its seed so poisonous it even kills birds>any bird that eats it dies and so it never has the chance to spread far and wide>eventually a bear comes and rubs its ass on the bush and destroys the plant
