The domestication of plants and animals lead to great change in the development and structuring of communities, as the hunter-gatherer lifestyle was slowly replaced by permanent settlements of farmers and villages. We can see that the communities varied greatly dependent on their local ecology, the resources available, and the time period within which their community was based. The road to agricultural way of life in the MIddle East is characterized by Four distinct stages. It was during the Kebaran period, and Geometric Kebaran in which hunter-gatherers began to utilize the plant and animal resources of the region. Architecture became a prominent feature of the Natufian period, as communities began to transition to village life from that of hunting-gathering. Though it was during this period that material culture began to appear, and artifacts such as sea shells and beads were found traded long distances from the Red and Mediterranean Seas. During the Natufian period, agriculture had not yet taken hold, though the domestication of dogs was seen to have occured at both Hayonim Terrace, and Mallaha, as the skeletons of these creatures were found with human remains. It was during the Early Neolithic period of Middle Eastern history during which people began to live in villages and accept agriculture as a means of subsistence. It was the appearance of communal structures during this period which helped to permeate a sense of community planning and directionalism. The community in a sense had the ability to act as a group, as evidence of community activity was found in several structures which were used in ritual functions. It was during Pre-Pottery Neolithic B period in which the size of settlements increast drastically, as was the change to rectangular houses from those that were round≥ This change in shape allowed higher density in villages, and showed the natural progression towards planning and future development on the part of the community.

At around 12,500 B.C.E, the domestication of animals and plants first arose. The domestication of animals and plants allowed early humans to manipulate the standard of living and heredity of plants and animals. Domestication took generations to achieve due to understanding the environment they inhabit. Domesticators gained many advantages that they didn’t have when they were hunters and gatherers. Between 7000 B.C.E and 500 B.C.E, the domestication of animals and plants in Central and East Asia gave….
Domestication is defined in the article as the manipulation of plants and animals to suit human needs. The article states that it is a gradual process, and domestication itself is not initially the goal. Domestication is the result of human efforts over an extended amount of time in which a species evolves to fit a desireable genotype/phenotype. In the reading it is also stated that domestication may have sparked social change in Africa. With domestication came herding and pastoral lifestyle, a lifestyle….
Introduction to Microscope
Circa 1000 AD. = the first vision aid was invented (inventor unknown) called a reading stone.
Circa 1284= Italian, Salvino D’ Armante is credited inventing the first bearable eye glass.
1590= two dutch eye glass makers, Zaccharias Janssen and Hans Janssen experimented with multiple lenses.
1665= English Physicist, Robert Hooke looked at a silver of cork through a microscope lens and noticed some “pores” or “cells”.
1674= Anton Van Leeuwenhoek built….
Animal-assisted interventions in Historical Perspective
Serpell talks about how animals are connected to illness and recovery. He starts out by describing animistic belief and their interpretation of animals and their spirits. He states that followers of the animistic worldview believe that a sickness or misfortune is caused on a person because of an angry or malevolent spirit. Furthermore, he says that some people believe in going to the spirit world and becoming a spiritual guardian….
Domestication happens over a long period of time through a process called selective breeding. Wild dogs had been domesticated by humans to be pets and companions. Livestock, such as goats, sheep, cows, Etc. had been domesticated for food. Maybe there is more to it than that. People who attempted to tame individual foxes often said that there is a stubborn wildness that is impossible to get rid of. It suggests that foxes are harder to tame than most animals.

have identical DNA. Sometimes, plants are self-pollinated, producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots, which later sprouted new trees. When earthworms are cut in half, they regenerate the missing parts of their bodies, leading to two worms with the same set of genes. However, the ability to intentionally create a clone in the animal kingdom by working on the cellular….
Many different plant and animal species thrive in the rainforest environment, but it is the trees that define the way we see the rainforest. From the air, a rainforest looks like an enormous, green carpet. The canopy very rarely breaks, with no gaps between the trees. Beneath these trees, there are thousands of different types of plants. Living amongst the trees, vines, shrubs, ferns, and mosses are many different types of animals. These range from the smallest ant to the carnivorous (meat-eating)….
Transgenic Animals and Plants
What is a transgenic animal/plant?
A transgenic animal or plant is one that has a foreign gene (called a "transgene") inserted into its DNA. Transgenic animals and plants are sometimes called "genetically modified organisms" or GMO 's for short.
What is a transgene?
A transgene is the foreign gene that has been moved from one organism into a new organism by genetic engineering. For example, a bacterial gene that is inserted into a plant 's DNA would be a….
desert is the home to many plant and animal wildlife. Of course, to survive the hot and dry conditions, these wildlife have to be specially adapted to capture as much food and water as possible to sustain themselves. In the desert, it can get as hot as over 30 degrees in the day and below 16 degrees at night! This project will further explore a few of the plants and animals, as well some of their adaptations.
