Examples of aridity hypothesis in the following topics:
-
- The savannah hypothesis states that hominins were forced out of the trees they lived in and onto the expanding savannah; as they did so, they began walking upright on two feet.
- This idea was expanded in the aridity hypothesis, which posited that the savannah was expanding due to increasingly arid conditions resulting in hominin adaptation.
- The turnover pulse hypothesis states that extinctions due to environmental conditions hurt specialist species more than generalist ones.
- The Red Queen hypothesis states that species must constantly evolve in order to compete with co-evolving animals around them.
- The social brain hypothesis states that improving cognitive capabilities would allow hominins to influence local groups and control resources.
-
- The Nazca (or Nasca) lived near the arid southern coast of Peru from 100 BCE to 800 CE.
- The Nazca developed underground aqueducts, named puquios, to sustain cities and agriculture in this arid climate.
- Likely related to the arid and extreme nature of the environment, Nazca religious beliefs were based upon agriculture and fertility.
- Like the Moche, who lived along the arid northern coast of Peru during the same time period, it is thought that the Nazca may have been forced into decline by environmental change.
-
- The Inca also produced bounties in the Amazon rainforest and along the more arid coastline of modern-day Peru.
-
- Moche society was agriculturally based, but because of the arid climate, they invested heavily in the construction of a network of irrigation canals.
-
- Large reservoirs were developed to retain water from river systems in this arid climate where water was an essential resource.
-
- The great bulk of Domesday Book is devoted to the somewhat arid details of the assessment and valuation of rural estates, which were as yet the only important source of national wealth.
-
- Similarly, the ChimĂș along the northern coast of Peru, worshipped the Moon, rather than the Sun, probably due to the hot, arid climate and
their proximity to the ocean.
-
- Crusaders' arrival at Jerusalem revealed an arid countryside, lacking in water or food supplies.
-
- The Black Death is thought to have originated in the arid plains of central Asia, where it then travelled along the Silk Road, reaching the Crimea by 1346.
-
- The
Kurgan Hypothesis is the most widely accepted scenario of Indo-European
origins.
