Darwin would have said that a few owls were born with bigger eyes. The owls with the big eyes would survive better and have more offspring so the owls with small eyes were less common untill there were only big eyed owls. This is called natural selection.
she had large blue eyes.
The large eyes sockets in early mammals used to hold large eyes. The eyes of early mammals were very large and contained a wider pupil and a larger lens. The eyes were much better at seeing in the dark than many mammals are today.
They are very large. In fact, they take up so much of the owl's skull that there is no room for the muscles (such as human beings have) to move the eyes around. This is why an owl is able to swivel its head around to such a great extent (almost 180 degrees) On average, owls can rotate their heads 270 degrees. If humans had eyes in proportion to an owls, our eyes would be the size of saucers. NF

it has two large eyes.
Lamarck knew evolution was happening, his inaccuracies are in how he explained it. The first part of his theory is known as "use it or lose it" today. He said that use makes organs and structures bigger or more useful. Giraffes needed long necks, while blind cave fish lost their eyes. Darwin thought this idea was too simple, and replaced it with natural and sexual selection. The second major point Lamarck made was called acquired inherited traits. This means that traits that an organisms gets after it was born affects its offspring. This would mean that a bodybuilder would naturally get buff children, and that crabs that lost their claws would have clawless spawn. A famous experiment involving the mutilation of mice (which left their offspring unaffected) disproved this. Because of our knowledge of genetics, we say that variation is caused by mutations and not acquired traits.

large eyes to see in the dark
Owls have large eyes that help them search for food at night.
All nocturnal animals have large eyes. The eye of an owl helps it see better in the dark
Generally, animals that have large eyes and eye sockets had poor vision. So, early primates with their large eyes probably couldn't see very well and had large eyes to compensate.
