Cities are increasingly the fundamental socio-economic units of human societies worldwide, but we still lack a unified characterization of urbanization that captures the social processes realized by cities across time and space. This is especially important for understanding the role of cities in the history of human civilization and for determining whether studies of ancient cities are relevan...
M olecular biology has made considerable contributions to the study of human history from the earliest days of our species, when our ancestors began to walk on the savannah, to the dawn of civilization and the more recent history of mankind. The analysis of contemporary mitochondrial DNA, for example, has told us that Homo sapiens first appeared in Africa; the sequencing of the Neanderthal geno...

Malaria has been with us long before the dawn of civilization. It shaped the destiny of peoples, nations, and colonies, influencing the outcomes of ancient military campaigns. Malaria is suspected to have caused the death of Alaric, king of the Visigoths, after he sacked ancient Rome and that of the 18th-century English poet Lord Byron. The war against malaria has been long and hard. Looking ba...
The domestication of the horse ∼ 5.5 kya and the emergence of mounted riding, chariotry, and cavalry dramatically transformed human civilization. However, the genetics underlying horse domestication are difficult to reconstruct, given the near extinction of wild horses. We therefore sequenced two ancient horse genomes from Taymyr, Russia (at 7.4- and 24.3-fold coverage), both predating the earl...

In this paper we propose a new mathematical model capable of merging Darwinian Evolution, Human History and SETI into a single mathematical scheme: (1) Darwinian Evolution over the last 3.5 billion years is defined as one particular realization of a certain stochastic process called Geometric Brownian Motion (GBM). This GBM yields the fluctuations in time of the number of species living on Eart...
