Our place inside the Universe

In the 1970s, an American astronomer had the idea of creating a representation of the evolution of the universe on a calendar.

The (observable) universe, now 13.6 billion years old, is placed on the calendar. Birth on January 1 at 0:00, the dinosaurs die out on December 30, and man (who only appeared in the year -100,000)... on the morning of the last day of the year.

Over a one year scale:

In the history of life, we are the last to appear. Living organisms have adapted throughout their evolution, and the changes brought about by man are only very recent!

Sir Charles Darwin laid the foundations for a theory that is now well studied, which explains that nature has made millions and millions of attempts, and only those adapted to the environment can survive. This evolution has taken place over hundreds of thousands, millions of years.

Organisms are not adapted to artificial lighting. And they won't have time to adapt before irreparable damage is done to the species in question.

This change has taken place over a few decades. From an evolutionary point of view, this is far too fast for organisms to adapt.

No, it's not fast? ah, maybe you're suffering from ecological amnesia without realizing it?
