comment Convergent evolution of fruits
Squirrels mostly eat nuts which are not intended to be eaten because their seeds are destructed in the process thus there is no surprise that nuts typically have no attractive color.

comment What's the purpose of colorful mushrooms' caps?
Are you claiming all color is due to toxins??? Then you have to explain why non-toxic Russula has the red cap en.wikipedia.org/wiki/Russula and why the most toxic species such as the Amanita phalloides are usually uncolored en.wikipedia.org/wiki/Amanita_phalloides

comment Convergent evolution of fruits
@3cat under fruits I explicitely mean those tissues intended to be eaten by animals. I am not interested in the other varieties. I ate durian, and as it was fresh I did not notice any distractiong smell. Do you claim it is not intended to be eaten? What's the purpose of it then?

comment Convergent evolution of fruits
Cucumbers are green just because we eat not ripe cucumbers. Ripe cucumbers are yellow. Blue berries are just too dark red with a fungal film on the surface. I define fruits as the tissues intended by the plant to be eaten by the animals.

comment Do birds have navels?
I doubt it falls off, the sources I looked up say that the whole yolk sac goes inside the bird's body.
