These issues are embedded:
1. Define macroevolution, coevolution, convergent evolution and mosaic evolution.
2. Why is adaptation so important to evolution?
In evolutionary terms, we define macroevolution as evolution at or above species level. It means either splitting of a species into two species (cladogenesis) or change of a species over time into another species (anogenetic speciation).
Coevolution is a change in the genetic composition of one species (or group) in response to a genetic change in another. More generally, the idea of some reciprocal evolutionary change in interacting species is a strict definition of ...
This job clarifies these terms: macroevolution, coevolution, convergent evolution and mosaic evolution.
