Question

Quizplus · Accepted Answer

The model of species selection involves the differential survival and reproduction of species, just like natural selection involves the differential survival and reproduction of individuals within a population. In this analogy, the species are like the individuals, and speciation is like reproduction. Option A is incorrect because major groups of organisms do not fit the definition of species, and extinction is not directly analogous to reproduction. Option C is incorrect because genes are not equivalent to entire populations or species. Option D is incorrect because families are too broad a category to be considered equivalent to individuals within a population.
