Respond to the following prompt in your notebooks: “Describe the life of prehistoric man.” The change in the inherited characteristics of biological populations over successive generations Example: Australian Shepherd tails Walking upright? Developing language? Harnessing fire? Developing tools? http://www.youtube.com/watch?v=gZps VSVRsZk Adaptation – A trait that helps an organism survive and reproduce. Ex: developing eyes, developing lungs Natural Selection – The process by which individuals that are better adapted to their environment are more likely to survive. In the space below, list some of the adaptations that our species made along our evolutionary path to survive and reproduce: __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ __________ “How might we evolve in the future?” 100 words Turned in tomorrow Read pgs. 51-55 in the textbook and complete pg. 55 #1-5 Answer in complete sentences As I check your homework, use your BYOT devices to look up images of the following: Stone age ANIMALS Stone age TOOLS Stone Age ART Work with a neighbor and discuss what you see Greek – “Old Stone Age” About 2 million B.C. - 10,000 B.C. Hunter-gatherers Nomads Moved from place to place with no settled home Traveled in bands, or small groups of related families Migration – movement from place to place Click Here! Developed simple tools (stone, bone, wood) Developed spoken language Invented clothing to survive Ice Age Ice Age lasted from approximately 110,000 to 10,000 years ago Learned to build fire Start of religion Animal worship Began burying the dead at the end of the Old Stone Age, development of idea of afterlife Read pgs. 56-59 in the textbook and complete pg. 59 #1-4 Answer in complete sentences HUNTING/GATHERING FARMING Advantages: Advantages: Disadvantages: Disadvantages: Greek – “New Stone Age” About 10,000 B.C. to around 3,000 B.C. People began to farm – Agriculture Domesticated crops Domesticated animals Use of advanced stone tools and pottery People begin to settle in set areas What type of areas might people begin to settle in? Advantages: 1. Animals had to be fed 2. Agriculture relied on steady weather and water supply 3. People began to fight over land 4. People had to stay in one place Disadvantages: 1. Domesticated animals (livestock) can be bred and used for meat, milk, and wool 2. Domesticated crops provide stability to the food supply 3. Populations began to grow faster 4. People could stay in one place 1. What new way of getting food changed societies? A) Agriculture, or farming, changed societies dramatically. 2. How did early people become food producers? What effect did this change have? A) Early people noticed that seeds from plants can grow new plants. The effects of this included the domestication of animals, establishment of year-round settlements, an increase in population due to stability in the food supply, and conflict over land. 3. Why did farming societies feel a need to control land while huntergatherer societies did not? A) Farming requires control of the land being farmed for an extended period in order to reap the harvest. 4. Clearing forest land today affects the environment just as clearing wild plants did long ago. What were the effects then? What are they now? A) Then: The land was fertilized by the ashes of the burnt plants. Now: Sometimes the same effect is had. Other times, rapid land development can lead to endangerment of species by destroying their habitat.
