If the history of the earth occupied one year how long would human evolution be?

If we assume "evolution of humankind" to include back to the point of divergence from other apes, then we would use the rough estimate of 6 million years. Out of a 4.54 billion year old Earth, this is a proportion of 1:756.67, or 1/766.66.

Dividing this into the number of days in a year, we would get 0.4824 days or 11.58 hours of human evolution for every year.
