Do newborn mammals dream? But how DO they?

Can someone explain:

As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?

A new Yale study suggests that, in a sense, mammals dream about the world they are about to experience before they are even born.

Writing in the July 23 issue of Science, a team led by Michael Crair, the William Ziegler III Professor of Neuroscience and professor of ophthalmology and visual science, describes waves of activity that emanate from the neonatal retina in mice before their eyes ever open.

This activity disappears soon after birth and is replaced by a more mature network of neural transmissions of visual stimuli to the brain, where information is further encoded and stored.

“At eye opening, mammals are capable of pretty sophisticated behavior,” said Crair, senior author of the study, who is also vice provost for research at Yale.” But how do the circuits form that allow us to perceive motion and navigate the world? It turns out we are born capable of many of these behaviors, at least in rudimentary form.”

In the study, Crair’s team, led by Yale graduate students Xinxin Ge and Kathy Zhang, explored the origins of these waves of activity. Imaging the brains of mice soon after birth but before their eyes opened, the Yale team found that these retinal waves flow in a pattern that mimics the activity that would occur if the animal were moving forward through the environment.

The paper is closed access.

Surely this is not possible without design in nature. Too much information.

Note: Anyone familiar with kittens will have noticed this. The kittens begin to behave like cats as soon as they have acquired neurological competence with their own limbs.

But that takes several weeks.

    Some pre-programmed knowledge about the world is obviously necessary and present. Animals know what they’re meant to eat without training, and have built-in responses to good face shapes and bad predator shapes.

    It’s not a stretch to add pre-programmed ‘dramas’. What to expect when you walk, what to expect when you eat, etc. Those ‘dramas’ are running on the stage of consciousness during dreams, before the play starts to be revised by your own experiences.

    Ore-born babies can hear and feel a LOT of stuff about Mom. And they can even TASTE some foods, about which they complain to Mom.
    But these are Growth things: Junior NOTICES more and more things every day.
    Oh, I saw something on TV, lo! these many decades ago, about the fact babies believe they are the ONLY Intelligence in the world/universe. And so they growing increasingly angry when the world does NOT do what they wanted it to do. Someplace AFTER BIRTH, babies SUDDENLY discover/conclude that Mom MIGHT be independent of their will/universe. And it’s all downhill from there.

    That doesn’t make sense there would be no reason for learning

    Sounds to me like setting up a framework on which the learning can be hung in an orderly fashion so that it is actually useful in the real world. Or perhaps like outlining a paper before you write it as another analogy.
