Rope making more than 40,000 years old
If they had rope and twine, they had thread. If they had thread, they probably had some form of garments. If they had twine, they had the “technology” for bows and arrows. If they had rope they would also have had the capability to drag heavy weights across primitive rollers. Continue reading

Harappan civilisation started earlier, lasted longer
What is striking is how the two great rivers, the Indus and the Saraswati (Ghaggar or Hakra), totally dominated the landscape. It is not surprising that an advanced water management “technology” developed. The growth of managed agriculture and trade followed. The period of intensified monsoon from 7,000 BCE to about 5,000 BCE could have been a time of plenty which promoted growth and settlement. Continue reading
80,000-120,000 year old modern humans in S China confirm many and older Out of Africa events
The single Out of Africa event for modern humans is clearly far too simplistic. It is also clear that there were many back to Africa movements as well. Humans expanded sometimes because their old habitats were no longer viable. But, it seems, humans also explored and expanded into new territories from regions of plenty and where they maintained some contact with where they had come from. Probably, just because they could.

Earliest common ancestors could not have been mitochondrial Eve and Y-chromosomal Adam
African AMH is thought to have first come into being around 200,000 years ago in Africa. But it is thought that the ancestors of the Neanderthals and the Denisovans left Africa about 500,000 years ago. This immediately means that mitochondrial Eve and Y-chromosomal Adam could not have been our earliest common ancestors. Continue reading
Our Neanderthal genes may have come mainly from their females
So I imagine the decline of the Neanderthals taking some 20-30,000 years as AMH expanded westwards and the decline of the Denisovans probably starting a little later but taking somewhat less time. The encounters and admixing probably only occurred with the tribes and bands at the frontiers. Continue reading

Scavenging came long before hunting
So the timeline I envisage for the development of human activity takes us from foraging to scavenging to hunting to herding to transient agriculture and finally to settled agriculture. Continue reading
Once upon a story …….
It is not important to my narrative that any or all of these assumptions are proven – only that they are feasible. What is important though is that none of the assumptions be demonstrably false Continue reading
