“…2A–C) to estimate the time of divergence, resulting in the estimation of 3,400–6,700 years BP. This time frame is supported by recent archeological evidence (Haas et al 2013) and implies that after domestication, maize cultivation rapidly expanded to temperate America (Fig. 2D).…”

The temperate-tropical division of early maize germplasm to different agricultural environments was arguably the greatest adaptation process associated with the success and near ubiquitous importance of global maize production. Deciphering this history is challenging, but new insight has been gained from the genomic, transcriptomic and phenotypic variation collected from 368 diverse temperate and tropical maize inbred lines in this study. This is the first attempt to systematically explore the mechanisms of the adaptation process. Our results indicated that divergence between tropical and temperate lines seem occur 3,400-6,700 years ago. A number of genomic selection signals and transcriptomic variants including differentially expressed individual genes and rewired co-expression networks of genes were identified. These candidate signals were found to be functionally related to stress response and most were associated with directionally selected traits, which may have been an advantage under widely varying environmental conditions faced by maize as it was migrated away from its domestication center. It’s also clear in our study that such stress adaptation could involve evolution of protein-coding sequences as well as transcriptome-level regulatory changes. This latter process may be a more flexible and dynamic way for maize to adapt to environmental changes over this dramatically short evolutionary time frame.

“…We proposed three models (detailed in the Materials and Methods section, Figure 2A-2C) to estimate the time of divergence, resulting in the estimation of 3400-6700 years BP. This time frame is supported by recent archaeological evidence (Haas et al, 2013) and implies that after domestication, maize cultivation rapidly expanded to temperate America ( Figure 2D). The molecular evidence thus suggests that improvement and adaptation in maize may not have been sequential and discrete processes, but overlapped.…”

The temperate-tropical division of early maize germplasms to different agricultural environments was arguably the greatest adaptation process associated with the success and near ubiquitous importance of global maize production. Deciphering this history is challenging, but new insight has been gained from examining 558 529 single nucleotide polymorphisms, expression data of 28 769 genes, and 662 traits collected from 368 diverse temperate and tropical maize inbred lines in this study. This is a new attempt to systematically exploit the mechanisms of the adaptation process in maize. Our results indicate that divergence between tropical and temperate lines apparently occurred 3400-6700 years ago. Seven hundred and one genomic selection signals and transcriptomic variants including 2700 differentially expressed individual genes and 389 rewired co-expression network genes were identified. These candidate signals were found to be functionally related to stress responses, and most were associated with directionally selected traits, which may have been an advantage under widely varying environmental conditions faced by maize as it was migrated away from its domestication center. Our study also clearly indicates that such stress adaptation could involve evolution of protein-coding sequences as well as transcriptome-level regulatory changes. The latter process may be a more flexible and dynamic way for maize to adapt to environmental changes along its short evolutionary history.

“…Even if a bottom-up organization is identified, ethnographic studies suggest it can easily be incorporated into a broader state structure (Hunt & Hunt, 1976). Collective institutions arising from highly mosaiked agricultural landscapes are thought to have emerged in the Indus Valley (Possehl, 1998;Wright, 2010), while similar conditions of subsistence diversification have been identified in the Preceramic Norte Chico region of Perú (Haas et al, 2013;Haas & Creamer, 2006;Shady Solís, 2006;Shady Solís & Leyva, 2003) and in the Middle Horizon Tiwanaku/Late Titicaca area (Bruno, 2014;Bruno & Whitehead, 2003;Capriles, Moore, Domic, & Hastorf, 2014;Janusek, 2008).…”

The Teotihuacan Valley has witnessed the rise and fall of various civilizations since it was first inhabited by sedentary societies 3,500 years ago. Given its location in a semi‐arid environment, Teotihuacan has featured prominently in debates about the role of water and water management in the development of sedentism, culture, primary states, and large, complex societies. While many previous discussions tended to echo Wittfogel's “hydraulic hypothesis,” focusing on the ability of an elite few to monopolize water resources, we instead turn to a growing corpus of research showing varied water management strategies through time potentially resulting in distinct patterns of social organization. In this palimpsest landscape hydraulic and agricultural strategies were constrained not merely by present environmental conditions, but also by very real and material legacies of previous behavior. We discuss the state of research regarding these adaptations (and social responses) to water scarcity from the Early‐to‐Middle Formative Period (1250–650 B.C.) through the independence of Mexico (A.D. 1810), noting how previous fundamental assumptions about agriculture and hydraulic management in the Teotihuacan Valley have led to a significant number of neglected concepts and potential adaptations. If we are to address the current destruction of the Teotihuacan Valley's ecological and cultural resources in response to national development and climate change, a historical‐ecological perspective is necessary to disentangle the relevant processes that have shaped the landscape—and the cultures residing within it—to this day.
