S.S. Ch.1 Lesson 2




How were the Homo sapiens more technological?
Developed more complex tools for specific purposes
They made tools from antler, bone, wood, and stone for cutting and scraping
Bone needles for sewing
They designed stone points attached to wood spears

How were the Homo sapiens smarter?
The development of language began to accelerate about 50,000 years ago greatly improving their communication
Better communication led to better planning, organizing, sharing ideas, sharing knowledge, and to creativity
How were they creative? They began to create jewelry, cave painting, and sculptures to form religious beliefs.



Way of Living
Like earlier hominids, humans survived by living in groups, made of related family members with a total of about 30 people.
Learning to adapt gave them a better chance of survival
They lived in a wide variety of shelters such as caves, rock ledges, dried mud, tree branches, or other resources available to them.
Responsibilities of Men and Women
For food, women gathered wild grasses, nuts, and seeds.
Dug plant roots and picked fruit from bushes and trees
They share and feed all members of the group



On the Move
Groups of hunters and gatherers were always on the move, which means that they had no permanent home
They lived in different places in different seasons. As the weather changed and food could no longer be found, they moved to the next place.
They also followed animal migrations but this required them to move more often
They learned consequences, the result of an action quickly. For example, if eating a certain food made them sick, they avoided eating it again



Moving Across the Continents
How did they migrate?
The most widely accepted theory is the change of climate
During the Ice Ages, the water level dropped about 300 feet(91.44 meters) revealing land bridges between different continents
They began to migrate into Europe, Asia, Australia, and eventually to the Americas
