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.

What are the large eyes sockets in early mammals used for?

What are lamarcks ideas?
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.

What do desert rats use there eyes for?
large eyes to see in the dark
Who proposed that acquired traits could be passed on to offspring?
This is a theory that states that some characteristics of an individual are acquired as opposed to inherited. For example, some frogs have mutations because of pollutants in their environment, whereas a person who has blue eyes probably has them because they inherited them from their parents.
What kind of bird has a large eyes that searches for food at night?
Owls have large eyes that help them search for food at night.
How did the owl get such large eyes?
All nocturnal animals have large eyes. The eye of an owl helps it see better in the dark
What do the large eye sockets of early primates indicate that these animals probably did?
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.
Why would birds avoid animals that have large eyes in the front of their head?
Many predatory animals, such as owls or lions, have large, front-facing eyes to help them locate prey. Birds that avoid animals with this feature have a better chance of not being eaten.
