The most recent of the drying trends in the region commenced around 1,500 years ago at a time when the archeological and proxy records began to show definitive signs of increased human presence on the island. Ashish Sinha, professor of Earth science at California State University Dominguez Hills...
Generally, we found that threats related to agriculture and urbanization are more frequently related with other threats. In practical terms, it means that if we are going to eliminate, or at least reduce the presence, of those types of human activities we will be more likely to also reduce ...
Recognizing the dawn of ethnomicrobiology is essential as the field evolves from a descriptive to a more theoretical and integrative biological approach. We emphasize the critical role that traditional communities have played in conserving food, agriculture, and health systems. This emerging field highlig...
Human gene annotations were obtained from the ENSEMBL database87(genome reference version GRCh37), which was accessed using the R biomaRt package88,89(v.2.36.1). Of the 24,554 annotated ‘genes’ on the biomaRt database, we removed any that were not annotated in the NCBI database (ftp:/...
How did agriculture change the way Africans lived? How did chattel slavery begin? How did the Neolithic Age impact human history? How does capoeira have Indigenous peopl roots? How has the War on Terror evolved? How have microbes affected human history?
Genetic engineering also promises a revolution in agriculture. Recombinant DNA techniques enable scientists to produce plants that are resistant to herbicides and freezing temperatures, that will take longer to ripen, and that will manufacture a resistance to pests, among other characteristics. ...
It is generally assumed that death from malaria increased between 10 000 and 5000 years ago with the development of agriculture and settlements. These changes are thought to have increased both the density of the malaria mosquito vector and human population density, thereby greatly facilitating the...
Global agricultural production doubled four times between 1820 and 1975. Intensified animal production was seen as a way of providing food security and better nutrition. Pigs and cows began to be raised on factory farms in 1960s North America. Production shifted from the traditional model of exten...
In Mesopotamia (modern-day Iraq), calendars were first used approximately 3100 BC. A year was divided into 12 lunar months, each of 29 or 30 days, according to the Sumerian calendar. Observing a new moon began each month, making this a lunisolar calendar. As a result of the diversity of...
smelted down in April 1986. In a 2015 study, researchers reported finding an “an abundant mammal community after nearly three decades of chronic radiation exposures” and suggested that prior to the accident, “mammal populationdensitieswere likely depressed due to hunting, forestry and agriculture....
