Why did disease spread during the Neolithic era?

Why did disease spread during the Neolithic era?

The Neolithic Revolution provided close contact between numerous domesti- cate animal species and humans. This close contact facilitated the transmission of novel pathogens into human populations. This transmission was supported by the large, sedentary populations that resulted from the Neolithic Revolution.

What diseases are common in hunter gathering populations?

Human populations in modern, westernized societies exhibit patterns of diet and physical activity that are associated with increased incidence of chronic and degenerative diseases, such as diabetes mellitus, hypertension, cardiovascular disease, and certain cancers, among others.

What sorts of illnesses are found in the West but not among hunter-gatherers?

Westernized populations are plagued by a plethora of chronic non-infectious degenerative diseases, termed as “civilization diseases”, like obesity, diabetes, cardiovascular diseases, cancer, autoimmune diseases, Alzheimer’s disease and many more, diseases which are rare or virtually absent in hunter-gatherers and other …

What caused the transformation of hunting and gathering society?

Hunting and Gathering Society Along with cooking, controlled use of fire fostered societal growth through communal time around the hearth. Physiological evolution also led to changes, with the bigger brains of more recent ancestors leading to longer periods of childhood and adolescence.

What changes in human health occurred as the result of the transition to agriculture?

Skeletal analysis of these early agricultural communities suggests that the transition to agriculture had an overall negative impact on human oral health, increased the incidence of infectious disease and nutritional deficiencies, and contributed to an overall reduction in human stature.

What change marked the Neolithic Revolution?

The Neolithic Revolution, also called the Agricultural Revolution, marked the transition in human history from small, nomadic bands of hunter-gatherers to larger, agricultural settlements and early civilization.

What is the health of hunter-gatherers?

Hunter-gatherer populations are remarkable for their excellent metabolic and cardiovascular health and thus are often used as models in public health, in an effort to understand the root, evolutionary causes of non-communicable diseases.

Which disease condition was common in hunter-gatherer pre agricultural populations?

Bone and dental pathologies (e.g. osteoarthrosis, systemic stress, bone infections, trauma, caries, periodontal disease, antemortem tooth loss, and dental calculus) were considered.

How does Yersinia pestis reproduce in humans?

pestis infects the lungs, can spread to people through infected droplets. This means that if a person or pet with pneumonic plague coughs or sneezes into the air, you can catch the bacteria — and get pneumonic plague — if you inhale those infected droplets.

When did hunter gatherer culture change to maize farming?

At Dickson Mounds, located near the confluence of the Spoon and Illinois rivers, archaeologists have excavated some 800 skeletons that paint a picture of the health changes that occurred when a hunter-gatherer culture gave way to intensive maize farming around A. D. 1150.

What was life like before the Agricultural Revolution?

But modern hunter-gatherer societies that have rubbed shoulders with farming societies for thousands of years don’t tell us about conditions before the agricultural revolution. The progressivist view is really making a claim about the distant past: that the lives of primitive people improved when they switched from gathering to farming.

Why did people adopt agriculture as a way of life?

Of course they adopted it because agriculture is an efficient way to get more food for less work. Planted crops yield far more tons per acre than roots and berries. Just imagine a band of savages, exhausted from searching for nuts or chasing wild animals, suddenly grazing for the first time at a fruit-laden orchard or a pasture full of sheep.

What was life expectancy in pre agricultural world?

“Life expectancy at birth in the pre-agricultural community was about twenty-six years,” says Armelagos, “but in the post-agricultural community it was nineteen years. So these episodes of nutritional stress and infectious disease were seriously affecting their ability to survive.”
