Eagles are some of the most amazing creatures in today's world and they have similar designs. Eagle eyes are incredible examples of design that are not easily explained by any chance hypothesis.

The human eye has two kinds of receptors in the retina — rods and cones. Rods are more sensitive and give vision in dim light. Cones provide us with color vision. We do not see color in dim light because only the rods are sensitive enough to function. Cones are concentrated in the center of our retina in an area called the macula to help us see fine details.

A typical section of the human eye has roughly 200,000 cones, while eagle eyes have over 400,000. That means an eagle can see fine details that humans cannot. The reason for this design is obvious — eagles are carnivores. They must have incredibly sensitive vision to see their prey while in flight. Experiments with pet eagles have shown they can see a rabbit in a field while flying 1,000 feet above the ground.

The problem with this sensitivity is how to keep direct sunlight from damaging the cones. To solve this problem, eagle eyes have an eyebrow ridge that shades the cones. All eagles have this feature and use it in hunting their prey.

Eagles are designed to be apex predators. They are the perfect carnivores with talons to grasp prey, wing feathers that allow fantastic flight abilities, and powerful wings to lift heavy prey. Eagles keep a balance in nature and are essential in the stability of life forms worldwide.
