Dr Christian's Repetitive Big Bangs
I have currently completed the first thirty three lectures. With less verbal repetitions and "OKs" these lectures could have been reduced to less than twenty. The subject matter is indeed informative but Dr Christian has the annoying habit of saying the same things over and over again, not only in the same lecture, but in subsequent lectures as well.

Amazing course offering a mind-opening perspective
The course embraces several disciplines and merges them into a new perspective. I highly recommend it to everyone, whatever your interests may be.
Some lessons may feel a bit slow, especially when talking about themes that one already knows. On the other hand, it is very useful for themes one has little familiarity with.

Big History: The Big Bang, Life on Earth, a Survey
It has been about 10 years since I first watched this lecture set, and it is a pleasure to be a part of. Dr. David Christian is very fluid, and communicates the diverse topics with ease and clarity. Learning from it a second time allows the learner to just ponder the complexity, synchronicity of events which led to our evolution and potential final destiny, if not sooner through our own poor choices. Very worth the investment from all aspects. I have watched over 1200 lecture sets since 2002, and value this course very much! Highly recommend it!

Totally new way to look at human history
I always felt that history should be connected with archeology, anthropology and linguistics. But I did not find any article or book that address my concern that human history did not suddenly jump start at the beginning of the written languages.
This course answers my long term wish to integrate all human knowledge into one long flow from the beginning of time to the end of time. Very satisfying course and it is well done.

Connecting the Dots
This has to be the grandest connect the dots effort ever. From the beginning to the end of time. Engagingly presented. Emerging from my space and time machine, I have a new appreciation for where we have come from and where we may be headed. Well done.

31 min
22: Paleolithic Lifeways
Using remains left behind by our ancestors and studies of modern societies that still use stone technologies, modern researchers have constructed a portrait of the Paleolithic way of life. In this lecture, we enter into this world and learn what life was like for our distant ancestors....
31 min
23: Change in the Paleolithic Era
Change was gradual over the course of the long Paleolithic era, but there were some significant shifts that altered lifeways for human beings. These include climate changes during two ice ages, the rise of various technological innovations, and adaptive migration to nearly all parts of the globe....
32 min
24: Threshold 7-Agriculture
The appearance of agriculture set human history off in entirely new directions by increasing human control of food, energy, and other resources. The development of agriculture brings about changes in the environment and lays the foundation for the development of more complex human societies....
30 min
25: The Origins of Agriculture
Why, after 200,000 years of foraging, should human communities in quite different parts of the world take up agriculture almost simultaneously? In this lecture, we explore the different factors leading to this innovation....
30 min
26: The First Agrarian Societies
Although early agrarian societies left behind no written record, there is evidence of many important new developments during this period. Here, we explore the lifeways of these societies, and question whether agriculture meant the early farmers lived better than their forager ancestors....
32 min
27: Power and Its Origins
Approximately 5,000 years ago, the human species saw the rise of a new form of social organization: the first "tribute-taking" states. We begin our consideration of these states by asking how power is defined and what forms it takes....

33: Long Trends-Expansion and State Power
In this lecture, we begin to take the long view of agrarian civilizations, marking two trends that occurred during the course of 4,000 years: the expansion of civilizations to cover larger regions and incorporate more people, and the increasing power and reach of their rulers....
31 min
34: Long Trends-Rates of Innovation
Agrarian civilizations were able to expand because they developed new ways to extract resources and manage populations. This lecture examines how features such as population growth, commerce, and tribute-taking states helped encourage innovation....
31 min
35: Long Trends-Disease and Malthusian Cycles
Throughout human history, we see periods of innovation, population growth, increasing trade and urbanization, political expansion, and cultural efflorescence. Then, sometimes quite suddenly, there is a crash. In this lecture, we examine the factors that contribute to this cycle of boom and crash, referred to as the Malthusian cycle....
29 min
36: Comparing the World Zones
The previous two lectures describe factors that both stimulated and limited growth in the era of agrarian civilizations in Afro-Eurasia, the largest of the four world zones of human history. Here, we begin to question whether these same features and processes appear in American, Australasian, and Pacific zones....
31 min
37: The Americas in the Later Agrarian Era
