The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth.
Bob lived in an area that was known for its wildlife including deer. Once there had been larger predictors like wolves and mountain lions but they had been extinct in this area for decades. Now the other animals like deer had no natural predators.
Is the deer populatin increasing or decreasing?
