Exam 2: Why Is Evolution Important to Anthropologists

In Darwinian terms, who are the fit?

Natural selection acts on

The principle of Mendelian inheritance in which an individual gets one gene for each trait from each parent is the principle of

For modern biologists, a species is defined as

The panda's elongated wrist bone or "thumb" would be explained by Darwin's theory in which of the following ways?

The notion that natural disasters, such as floods, are responsible for the extinction of species, which are then replaced by new species is known as

Because evolution typically occurs over a long period of time, there is substantial material evidence to substantiate it as a viable theory.

The level of the Linnaean taxonomy in which different species are grouped together on the basis of their similarities to one another is called a

The way in which genotype and environment interact to produce a phenotype is measured by the

At 6,000 calories a day, a person with genotype X will weigh 285 lbs with much energy and high cholesterol levels. At 3,500 calories a day, the person will weigh 200 lbs with much energy and slightly elevated cholesterol levels. At 1,800 calories a day, the person will weigh 175 lbs with little energy and low cholesterol levels. These are examples of that genotype's

The observable, measurable outward characteristics of an organism are called the

The sum total of all the genetic information about an organism, carried on the chromosomes in the cell nucleus is called the

Darwin's theory that the "fitter" survive and reproduce more offspring, who then inherit the traits that made their parents "fitter" is called

That view that every "natural kind" of living thing is characterized by an unchanging core of features and separated from all other natural kinds by a sharp break is
