Unit 4 
For the past four weeks we have studied attachment theory, beginning with Harry Harlow’s experiments with monkeys. In those experiments, researchers took baby monkeys from their mothers. The monkeys had many emotional problems without their mother’s love. We also studied john Bowlby. His work showed us that human babies need a sense of security, too. Without this security from an adult, they have problems in future relationships. Finally, we looked at Phillip Shaver’s recent ideas about attachment theory and romantic love. 
Your assignment is to plan a class presentation of 10 to 15 minutes. First, select tow of the researchers we studied. You will briefly summarize their research and then explain which scientist’s work you think will have the greatest impact on people today. Be sure to support your opinion with reasons. 


 Unit 5 
There are fewer than 800 mountain gorillas in the world. They live in four national parks. In Africa. Mountain gorillas live in family groups with as many as 40 gorillas, Adult male gorillas can weigh over 400 pounds (180 kilograms).

Unit 6 
Bernard Weber wanted to use modern technology to bring the people of the world closer together. He knew that the original Seven Wonders of the Ancient World were chosen by one person. Si of the wonders don’t exist anymore. So he created a way to let the world determine the New Seven Wonders: an open election using the Internet and text messaging. Anyone could nominate a special site, and anyone could vote. Naturally, many people voted for sites in their own countries. In some places, people were encouraged by their government to vote. Sites in 220 countries were nominated, so there were plenty of wonders to vote for. Millions of votes were registered, and on July 7th, 2007, the seven winners were announced in Lisbon, Portugal. Fourteen finalists were also announced-perhaps because it was difficult to limit the Wonders of the World to only seven. 


Unit 7 
Anthropologists, scientists who study human beings, have long said that modern humans first lived in Africa, and then moved east toward Asia, north across the Mediterranean, and later throughout the world.  
Now a very large genetic study supports that theory. They study looked at nearly 1,000 people in 51 places around the world. It found the most genetic diversity in Africa, and less genetic diversity farther away from Africa. How did this happen? When small groups of people moved away, they took only a small amount of all the possible genetic information with them. People in the small groups reproduce. Their offspring inherited their parents’ more limited set of genes. Their traits were very similar to those of their parents. This process continue as small groups of people continued as small groups of people continued to move farther from Africa.
