(Phys.org)—The ‘brightest’ thing in nature, the Pollia condensata fruit, does not get its blue colour from pigment but instead uses structural colour – a method of reflecting light of particular wavelengths- new research reveals. The study was published today in the journal PNAS.

Dr Beverley Glover from the University of Cambridge’s Department of Plant Sciences, who jointly led the research, said: “This obscure little plant has hit on a fantastic way of making an irresistible shiny, sparkly, multi-coloured, iridescent signal to every bird in the vicinity, without wasting any of its precious photosynthetic reserves on bird food. Evolution is very smart!”Read more at: http://phys.org/news/2012-09-african-fruit-brightest-nature-pigment.html#jCp

Signs Humans are still evolving -

Originally, we all had brown eyes. But about 10,000 years ago, someone who lived near the Black Sea developed a genetic mutation that turned brown eyes blue. While the reason blue eyes have persisted remains a bit of a mystery, one theory is that they act as a sort of paternity test. “There is strong evolutionary pressure for a man not to invest his paternal resources in another man’s child,” says the lead author of a study on the development of our baby blues. Because it is virtually impossible for two blue-eyed mates to create a brown-eyed baby, our blue-eyed male ancestors may have sought out blue-eyed mates as a way of ensuring fidelity. This would partially explain why, in a recent study, blue-eyed men rated blue-eyed women as more attractive compared to brown-eyed women, whereas females and brown-eyed men expressed no preference.

Your eyes can paint colors onto blank objects. I swear! Just stare at the red dot in the optical illusion above for 10 seconds twice and you’ll see the black and white cityscape be transformed into a brand new colorful world. Each building will have its own nuanced color. Magic!
