On this episode of Conversations with History, UC Berkeley's Harry Kreisler talks with Elizabeth Jones, Assistant Secretary of State for Europe and Eurasia, about U.S. foreign policy and the change after 9/11. (53 min)
In this 7th grade humanities lesson, students prepare Ghanaian Black-Eyed Peas and examine the exchange of foods between Eurasia, Africa, and the Americas during the Columbian Exchange.

"Climate change stands to have a tremendous impact on the world’s freshwater ecosystems. To understand how, researchers analyzed 15,289 functional genes related to nutrient cycling and stress processes gathered from biofilm microbes across mountainside streams in Norway, Spain, and China. With increasing elevation, microbial functional diversity tended to decline, and the composition of functional gene assemblages tended to differ more with greater elevational distances. These variations were more drastic as the environmental differences between the lowlands and the peaks increased. The best predictors of these variations appear to be climatic factors, such as temperature during the growing season. and winter precipitation. Including predictors at the local or landscape level could further refine the picture painted by these findings and help Eurasian countries anticipate significant alterations to their stream ecosystems amid a changing climate..."

This is a remixed version of World History: Culture, States, and Societies to 1500 by Berger, et al. It's a textbook suitable for the World History survey. I have reorganized the text in order to provide a more globally integrated narrative. Each chapter invites students to compare and contrast developments across regions during a period of time.
This version of the book retains the text of the original but with updated references to chapters. I verified and, if necessary, updated links to online resources. In cases where the exact illustration used in the original version was not available, I have substituted equivalent ones. I also created and edited segues and other “connective tissue” as well to (hopefully) ensure that this version of the book reads as smoothly as the original.
Additional changes include:
More concise lists of “key terms” in each chapter
Expanded coverage of the Persian Empire
Expanded coverage of the end of the Yuan Dynasty
Added brief overview of the early Ming Dynasty including the voyages of Zheng He

"At first glance you would be hard-pressed to tell apart a Eurasian golden jackal from what has been thought to be an African golden jackal. Recent studies, however, suggest these geographically separate populations represent two distinct species. And one of them, it turns out, should be classified as a wolf. 19th century naturalists recorded and named many African mammalian species during their expeditions. Species descriptions were based on observations in the wild and on individuals collected and brought back to European natural history museums. These scientists were often over-zealous, naming more species than are currently recognized. But in the case of the African wolf, these early naturalists had it right. During the early part of the last century, golden jackals found in Eurasia and Africa were lumped into a single species due to similarities in their outward appearance, despite the fact that the early scientist had recognized the African form as a different, wolf-related species..."
