This lesson explores the transition from hunting and gathering to farming, examining key causes and effects that emerged after the last Ice Age. Warmer temperatures prompted the spread of species, while the extinction of Ice Age mammals forced people to adapt their food sources. As droughts emerged, food shortages demanded innovative solutions, leading to the first agricultural practices in places like Abu Hureyra. Understanding these historical shifts illuminates how climate and human adaptation interconnect in our food production evolution.

Do Now • What do you remember about the following topics? • Hunting and gathering • Adapting • Extinction • The end of the last Ice Age
Causes and Effects • At the end of the last Ice Age, there were many causes and effects that lead to the birth of farming.
Directions • Read the Adapting to Change section on page 49 of your textbook. • In your notebook, label the causes and effects that lead to farming.
Cause and Effect 1 • Cause: Warmer temperatures allowed people, animals, and plants to spread north and south from the equator • Effect: People began to see animals and plants they had never seen before.
Cause and Effect 2 • Cause: People now had additional food sources. • Effect: Where food was plentiful, populations grew.
Cause and Effect 3 • Cause: Many Ice Age mammals became extinct. • Effect: Many people lost an important source of meat.
Cause and Effect 4 • Cause: Climate of southwestern Asia and other places grew drier, causing droughts. • Effect: Droughts caused food shortages.
Cause and Effect 5 • Cause: People had difficulty feeding themselves (growing populations, animal extinctions, droughts). • Effect: People adapted by storing food, or creating weapons to kill smaller animals.
Cause and Effect 6 • Cause: In southwestern Asia, gatherers tried planting the seeds of wild grasses. • Effect: They became the world’s first farmers.
Crops: Abu Hureyra • Rye • Barley • Einkorn (type of wheat)
