Clathrus ruber of the mature fruit bodies have been identified as carotenes, predominantly lycopene and "beta"-carotene—the same compounds responsible for the red and orange colors of tomatoes and carrots, respectively. Lycopene is also the main pigment in the closely related fungus "Clathrus archeri", while "beta"-carotene is the predominant pigment in the Phallaceae species "Mutinus caninus", "M. ravenelii", and "M. elegans". Clathrus ruber Clathrus ruber is a species of fungus in the stinkhorn family, and the type species of the genus "Clathrus". It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies
Evolution of human colour vision allow them to see a wider range of the electromagnetic spectrum. Secondly, new random connections would create wavelength opponency and the new wavelength opponent neurons would be much more sensitive than the non-wavelength opponent neurons.This is the result of some wavelength distributions favouring excitation instead of inhibition. Both excitation and inhibition would be features of a neural substrate during the formation of a second pigment. Overall, the advantage gained from increased sensitivity with wavelength opponency would open up opportunities for future exploitation by mutations and even further improvement.
