Question

Which statement correctly defines coevolution?A. two new species that differ from each other and their common ancestor in a particular traitB. two entirely unrelated species that end up with a similar trait as they adapt to similar conditionsC. two closely related species that evolve the same trait separately from each otherD. two entirely different species affecting each other’s evolution, as in predator-prey relationships

Answer 1

The statement that correctly defines coevolution is:

D: Two entirely different species affecting each other's evolution, as in predator-prey relationships.

Another example of coevolution is host-parasite relationship, which happens between totally separated species, but affects the way both of them will evolve.
