Why is black and white vision more adventageous for predators than color vision?
gpt
Your eyes have two receptors - - rods and cones. One dealswith color, but the picture is not very 'sharp'. 
The other sees black and white but is very sharp. 

So black and white vision tends to be sharper accurate than color vision. 

Also black and white receptors work better in low light. Which is obviously good for predators hunting at night. 

This is why you can sometimes see stars in the sky better by looking through your peripheral vision than dead on.
