Brown seems to be such a default colour for things in nature and in day to life. Why is it so common for things to be or turn this colour in contrast to the vast array of other colours around?
In: Earth Science
If you’re talking about animals, that would mostly be due to the fact that mammals are the dominant land animals, and all mammals alive today had evolved after 100+ million years of being nocturnal to avoid the dinosaurs and pterosaurs.
Nocturnal animals have poor colour vision in exchange for night vision. So mammals lost most of the genes for developing vibrant colours.
Hence why birds fish and reptiles tend to be very colourful.
Life was much more vibrant before the KT extinction event (asteroid that killed the dinosaurs).
