Document Summary

How has this contributed to health problems in the u. s. a. : sugars, fats, and salts have become more available due to mass produced foods and monoculture crops. This has increased health problems in the usa because our bodies are not meant to have such high content of these nutrients. What are food deserts: an urban area where people have little or no easy access to nutritious food without traveling long distances. Why did modern agriculture create a divide between people and the environment: agriculture was used to create civilizations and now we have technology, there is no connection to the crops grown and the people who eat it. Mass production has taken away that connection with the land. What was the most significant development, technologically, of modern agriculture: the haber bosch process allowed us to add man made nitrogen into the natural system as synthetic fertilizers, allowing crops to grow more and faster.

They are the same.

The repeated domestication of grasses (i.e., cereals) and legumes across the globe is likely because:

Human populations were often starving, and needed an additional food source

Only grasses, not legumes, were repeatedly domesticated

Early technologies allowed early agriculturalists the ability to communicate with each other over long distances to discuss what plants were best for domestication.

Both already possessed all of the traits needed for domestication

Both contain almost all of the amino acids our bodies need to build proteins.

In discussing the origin of agriculture, the term demographic stress refers to:

That the stresses on pre-domesticated plant species led to the development of traits that result in the "domestication syndromeâ

In what way did Harlanâs theory give rise to Diamondâs theory?

It recognized that agricultural societies were healthier and better fed than hunter-gatherer societies.

It recognized agriculture might have developed by different mechanisms in different parts of the world.

It recognized the reason agriculture did not develop in certain parts of the world was because people lacked the intelligence or skill.

Both make the assumption that hunter-gatherers were (and still are) superior to agriculturists.

It is a basic case of scientific plagiarism - Diamonds theory is identical to Harlans theory.

What is the difference between classically bred varieties and landraces?

Landraces cannot be harvested using domesticated animals; classically bred crops can be harvested using domesticated animals.

Landraces have no means of seed dispersal; classically bred crops can readily disperse their seeds

Landraces are grown in dry conditions; classically bred crops are wetland species

Landraces are often (though not always) developed by unintentional processes; classically bred crops are developed by intentionally breeding for desired traits using modern techniques

Landraces are not edible by humans; classical bred crops can be eaten
