DrmDoc Posted April 8, 2018 Share Posted April 8, 2018 (edited) Researchers at the prestigious Lund University in Sweden have determined that a cryptochrome (CRY4) in eyes of birds enables their perception of Earth's magnetic field (magnetoreception). According the university's April 6th article: Quote ...researchers at Lund University have studied different proteins in the eyes of zebra finches and discovered that one of them differs from the others: only the Cry4 protein maintains a constant level throughout the day and in different lighting conditions. I imagine adaptations to the human eye may soon arrive. Enjoy! Edited April 8, 2018 by DrmDoc Link to comment Share on other sites More sharing options...
CharonY Posted April 9, 2018 Share Posted April 9, 2018 The conclusion have to be more careful.They found a candidate protein that, because of its expression pattern, might be involved in magnetoception. However, they have not determined whether it is really the case. Link to comment Share on other sites More sharing options...

JacobsLadder Posted April 12, 2018 Share Posted April 12, 2018 An interesting discovery for sure. Birds are a window into the past. It's amazing to think of the humble pigeon as a ruthless Jurassic predator. Link to comment Share on other sites More sharing options...
