What is true of macroevolution?

a. it is the same as microevolution, but includes the origin of new species.
b. it is evolution above the species level.
c. it is defined as the evolution of microscopic organisms into organisms that can be seen with the naked eye.
d. it is defined as a change in allele or gene frequency over the course of many generations.
e. it is the conceptual link between irritability and adaptation.

b. It is evolution above the species level.

Explanation:

Macroevolution is the evolution that generates new taxa, for examples two or more species from a common ancestor. Macroevolution is the product of microevolutionary processes, it is, of microevolution: the change in allele frequencies in a population over time.  Macroevolutive changes are commonly evident while not all microevlutive changes are not.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
