According to the recent study, in Psychological Science, we interpret a person’s emotions by analyzing the expression in their eyes – a process that began as a universal reaction to environmental stimuli and evolved to communicate our deepest emotions.
Why do animals that live in caves become blind? Charles Darwin originally suggested that eyes could be lost by “disuse” over time. Now, Reed Cartwright, an ASU evolutionary biologist in the School of Life Sciences and researcher at the Biodesign Institute, wants to get to the heart of the matter—and in a recent publication in the journal BMC Evolutionary Biology, may be proving Darwin wrong.

Research into retinal regeneration in zebrafish has identified a signal that appears to trigger the self-repair process, raising the possibility that human retinas can also be induced to regenerate, naturally repairing damage caused by degenerative retinal diseases and injury, including age-related macular degeneration and retinitis pigmentosa.
Researchers at Vanderbilt University in Nashville, Tennessee have discovered that in zebrafish, decreased levels of the neurotransmitter gamma-aminobutyric acid (GABA) cue the retina, the light-sensing tissue in the back of the eye, to produce stem cells. The finding sheds light on how the zebrafish regenerates its retina after injury and informs efforts to restore vision in people who are blind.
