Can echo location be used for depth perception?
- godelski 5y agoYes but it is very expensive. Here's some more on bats[0] (mentions expensive echolocation around 5:45 and moving from sonic location to echolocation evolution). Eyes do also convey more information. You can get colors in addition to depth and shape and that's a good reason and easy path for eyes to develop since light sensing is a pretty easy thing to develop. Also, bats aren't blind, despite common belief. [0] https://www.youtube.com/watch?v=zWeYCULC0UQ https://www.youtube.com/watch?v=zWeYCULC0UQ
- ncmncm 5y agoIt can. One eye and echolocation gives you everything you get with two eyes except redundancy. Cyclops got by with one eye and throwing rocks.
