– Secondary energy trap is what an organism uses to help it obtain food or to help is
conserve energy.
1. Human evolution

– Domestication of animals is an example of a symbiotic relationship. Man provides food
and shelter to the animals, and they provide meat, mild, and fiber for man.
– Because of this relationship, both humans and domestic animals are secondary energy
traps for the other; humans provide feed and care for the animals, while the animals
provide draft power, meat, skins, milk. fiber, etc..

secondary uses of the animals were realized: milk, wool, power, etc..
– A cultural revolution resulted as people were transformed from hunters and gathers to
herders and cultivators. This is what started the modern civilization.
– The end of the __________ period marked the beginning of domestication. The glaciers
began retreating 14,000 years ago. The full retreat was 11,000 years ago.
– People began harvesting wild grasses that were growing abundantly and storing them.
At this point in history, people could not leave for long periods of time for fear someone
could come along and loot their food sources. This is what led to small villages being
formed. This gradually changed the culture to what it is today.
1. Women no longer had to spend as much time gathering food. This increased birth
rate and decreased infant mortality.
1. Men now had to always hunt near the villages, which resulted on over hunting in
some areas.
1. More animals had to be domesticated for personal food supply.
1. Slowly, the human became more of a ________ and less of a __________.
