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.
Bill lives in the country. Over the last few years he has noticed that there are way more feral cats running around than there used to be. In fact he usually sees several litters of kittens each year. On the plus side he has noticed that there are a lot fewer mice getting into things in his barn or getting into his house.
Which population is experiencing less deaths than births?
