Śuddhodana was determined to see his son become a king, so he prevented him from leaving the palace grounds. But at age 29, despite his father's efforts, Gautama ventured beyond the palace several times. In a series of encounters—known in Buddhist literature as the four sights—he learned of the suffering of ordinary people, encountering an old man, a sick man, a corpse and, finally, an ascetic holy man, apparently content and at peace with the world. These experiences prompted Gautama to abandon royal life and take up a spiritual quest.
How old was Gautama when he first left the palace grounds?
29

The fossil record suggests that the last few million years featured the greatest biodiversity in history. However, not all scientists support this view, since there is uncertainty as to how strongly the fossil record is biased by the greater availability and preservation of recent geologic sections. Some scientists believe that corrected for sampling artifacts, modern biodiversity may not be much different from biodiversity 300 million years ago., whereas others consider the fossil record reasonably reflective of the diversification of life. Estimates of the present global macroscopic species diversity vary from 2 million to 100 million, with a best estimate of somewhere near 9 million, the vast majority arthropods. Diversity appears to increase continually in the absence of natural selection.

Strasbourg (/ˈstræzbɜːrɡ/, French pronunciation: ​[stʁaz.buʁ, stʁas.buʁ]; Alsatian: Strossburi; German: Straßburg, [ˈʃtʁaːsbʊɐ̯k]) is the capital and largest city of the Alsace-Champagne-Ardenne-Lorraine (ACAL) region in eastern France and is the official seat of the European Parliament.
