What is the history of milestones?

In order to be able to easily compare the periods of time that have passed one after the other in our history, we are going to repeat the game of comparing the duration of the whole path to a day and then insert the historical moments of interest:

00:00 hours the oldest traces of cumulative culture appear

14:38 hours the time the remains of the oldest homo sapiens are dated back

23:25 hours the end of last glaciation

23:37 hours emergence of agriculture

23:42 hours emergence of writing, the end of prehistory and birth of history

23:58:49 hours beginning of the industrial age

23:59:42 hours invention of the radio

23:59:58 hours spread of the internet and mobile phones

It therefore follows that until the last minute of our day, we lived hunting and gathering fruits as the last hominids that came before us; what we call history corresponds to about 18 minutes and the industrial age to 1 minute and 11 seconds. Also, if we consider that the oldest remains of our species date back to about 200,000 years ago, while the first intensive forms of agriculture appear about 6,000 years ago, it results that humanity has lived in tribes of hunters for 97% of its existence; finally, the period related to the industrial economy occupies the 0.15% of the history of our species. It is to be noted that cultural evolution had a sharp acceleration in the period of greater stableness of the climate and the ecosystem.
