Question 2
Which of the following statements best describes the evolutionary model presented by C. Darwin in On the Origin of Species?
A) organisms generally practice reproductive restraint. This allows all members of a species to be uniform in their traits. Changes in species (evolution) may be attributed to periodic divine intervention.
B) the members of any species vary among themselves and may be viewed as in competition with one another. Individuals possessing adaptive traits (one that aid in this competition) will survive and reproduce. Over time, the adaptive traits will spread within the species.
C) two or more physical types exist within species, one of which will ultimately prove to be fittest.
D) organisms generally produce fewer offspring then the environment can support. Evolution then acts to increase the reproductive success of all members of a species equally.
E) within every population there is competition. Those animals that refrain from competing will have greater rates of survival and reproduction than more aggressive individuals.
