We still don’t do that. I don’t think that is a sign of the image
when did humans begin to wear clothes,
I would suggest we will never know that. Grass skirts don’t fossilize. But we do know that as hominids moved into colder regions of the earth they would need clothing to survive. I did a calculation for Dmanisi Georgia where H. erectines (who were as hairless as us) lived with winters too cold to survive naked and without fire…
and when did humans begin to do small scale ag
Defining ag is tough. These people engage in activities like ag, but they are not agriculturalists.
“Studies of modern hunter-gatherers show that there is a correlation between population density and the specialised use of particular foods. Examples include the systematic exploitation (in some cases even involving the sowing) of wild grasses and other herbaceous plants for their seeds, and the replanting of wild yams and other tubers to ensure continuity of supply.” ~ D. R. Harris, “Human Diet and Subsistence,” in S. Jones et al, editors, The Cambridge Encyclopedia of Human Evolution, (New York: Cambridge University Press, 1992), p. 72-73
The evidence for digging them up goes back 1.9 myr or more at Swartkrans, South Africa. Is that ag? it is one part of ag.
and when did humans begin to have some form of judicial laws
When we obtained morality. Every family has its set of laws as well.
and when did humans begin to build cities ( village tribes) and so on.
About 12,000 years ago. It is a long story but without divine help, it would take millions of years for even those with the image to figure out how to make cities work. One must have spare forms of energy, like animal energy, and that requires domestication of animals. And then there is the issue that early farmers died much younger than hunter gatherers of the same period. This has led many huntergatherers to avoid farming. As one guy said when asked why he didn’t farm:
“Scattered throughout the world, several dozen groups of so-called primitive people, like the Kalashari Bushmen, continue to support themselves that way. It turns out that these people have plenty of leisure time, sleep a good deal, and work less hard than their farming neighbors. For instance, the average time devoted each week to obtaining food is only 12 to 19 hours for one group of Bushmen, 14 hours or less for the Hadza nomads of Tanzania. One Bushman, when asked why he hadn’t emulated neighboring tribes by adopting agriculture, replied, "Why should we, when there are so many mongongo nuts in the world?”" ~ Jared Diamond, “The Worst Mistake in the History of the Human Race,” Discover, 1987, in in D. Bruce Dickson, ed. Readings in Archaeology, (New York: West Publishing, 1994), p. 22
To let you know about mongongo nuts. I ran into this quote a while back:
“By far the most important food is the Mongongo (mangetti) nut (Ricinodendron rautanenii Schinz). Although tens of thousands of pounds of these nuts are harvested and eaten each year, thousands more rot on the ground each year for want of picking.
"The mongongo nut, because of its abundance and reliability, alone accounts for 50 per cent of the vegetable diet by weight. In this respect it resembles a cultivated staple crop such as maize or rice. Nutritionally it is even more remarkable, for it contains five times the calories and ten times the proteins per cooked unit of the ceral crops. The average daily per capita consumption of 300 nuts yields about 1,260 calories and 56 grams of protein. This modest portion, weighing only about 7.5 ounces, contains the caloric equivalent of 2.5 pounds of cooked rice and the protein equivalent of 14 ounces of lean beef.
“Furthermore the mongongo nut is drought resistant and it will still be abundant in the dry years when cultivated crops may fail. The extremely hard outer shell protects the inner kernal from rot and allows the nuts to be harvested for up to twelve months after they have fallen to the ground. A diet based on mongongo nuts is in fact more reliable than one based on cultivated foods, and it is not surprising, therefore, that when a bushman was asked why he hadn’t taken to agriculture he replied 'Why should we plant when there are so many mongongo nuts in the world.”
"Apart from the mongongo, the Bushmen have available 84 other species of edible food plants , including 29 species of fruits, berries, and melons and 30 species of roots and bulbs. The existence of this variety allows for a wide range of alternatives in subsistence strategy.” ~ Richard B. Lee, “What Hunters Do for a Living, or, How to Make Out on Scarce Resources,” in Richard B. Lee and Irven Devore, Man the Hunter, (New York: Aldine de Gruyter, 1968), pp. 30-48, p. 33
