- dr_zoidberg 10y agoI think something similar happened with dogs (no color cones), but then behavioral tests showed they have some limited color vision.
- corecoder 10y agoAre you sure about this? I seem to recall that dogs do have cones, just not many and not of as many varieties (that is, three) as we have.
- dr_zoidberg 10y agoI'm not a biologist nor vet, so not my area of expertise, but there are a lot of jokes about dogs being colorblind (tv series, movies, etc) and in the end it happens that they do have some limited color vision. Sorry I can't give any reference.
