50 10 Full Breakdown

Summary

Story summary

Trinity College Dublin researchers analyzed 237 animal species to show that sensory systems evolve to match an animal's way of life.
They used the critical flicker fusion (CFF) metric to measure time perception.
Fast-pursuit predators, such as eagles, process visual information more rapidly than slower animals like sea slugs.
Brighter environments are associated with faster vision.
The results were published in Nature Ecology & Evolution.
