Exam 2: Human Origins

The human species most probably originated five to seven million years ago in:

David Reich suggests that chimps and humanoids interbred for hundreds of thousands of years. This accounts for their genetic structure being almost identical.

To a great extent, the ability of people to live happy and satisfying lives depends on the nature of the society they live in.

Linnaeus's divisions were determined primarily by physical traits.

Recent DNA tests have indicated that Neanderthals were most likely genetically:

Edward Wilson helped advance the thesis of sociobiology with his work on fear of strangers.

What is sociobiology and how is it applied to human behavior? What problems do some social scientists find in sociobiology?

Gene splicing was not important in genetic engineering developments.

It is suspected that Neanderthals are the ancestors of modern humans.

Tool use may have led to more protein and fat in the early hominid diet and enlarged brains.

The conventional view is that the human species originated in Africa 3-5 million years ago.

Homo erectus was first discovered in 1891 in Java by:

Our future social evolution will likely be substantially influenced by the information we have about our human evolution.

Gorillas, like humans, live on the ground. Chimpanzees spend much of the daytime on the ground. One reason for this descent was their increase in size.

Average brain size of Homo erectus was smaller than people they had replaced.

Some scientists argue that language is not limited to humans and that linguistic ability is also possessed other species such as:

Science has no explanation for existence; evolution is a theory of change, not a theory of existence.

In 1953, James Watson and Francis Crick unraveled the double helix structure of:

The discovery of new fossils of birds challenged Gould's theory of punctuated equilibrium.

Darwin saw evolution as a rapid process with sudden abrupt changes.
