An insect eye looks so different from a human eye that one would assume intuitively that this must have arisen quite differently in evolution. There was a separate sort of construction ...

As far as evolution goes, that’s a blink of an eye. The mantle of the bay scallop (Argopecten irradians) is festooned with up to 100 brilliant blue eyes. Each contains a mirrored layer that acts ...

This dramatic increase in animal diversity, 545 to 530 million years ago, is known as the Cambrian explosion. The evolution of the eye is likely to have been a catalyst for the explosion, initiating ...

The eye would then be struck with a blunt object ... Today, routine wounds are <3 mm long, and 1 mm wounds are on the horizon. The evolution of smaller surgical incisions was matched by the ...

They also found eyespots in chiton may have originated even more recently and quickly — within 7 million years, far faster than another estimate that the evolution of the eye in vertebrates took ...

Many researchers have found the evolution of the eye attractive to study because the eye distinctively exemplifies an analogous organ found in many animal forms. Simple light detection is found in ...
