Example: Darwin’s Finches
In evolutionary biology, adaptive radiation is a process in which organisms rapidly diversify from ancient species to a wide range of new forms, in particular when environmental changes provide for new resources, create new challenges or open new niches to the environment.
In biology, a single-access key (also called "sequential key", "analytical key", or "pathway key") is a key where the sequence and structure of identification steps is fixed by the author of the key. At each point in the decision process, multiple alternatives are offered, each leading to a result or a further choice. The alternatives are commonly called "leads", the set of leads at a given point a "couplet". If the entire key consists of exactly two choices at each branching point, the key is called dichotomous, otherwise it is described as polychromous (or, in false analogy, "polychotomous"). The majority of single-access keys are dichotomous.

Human skin cells are eukaryotic.
Prokaryotic cells are unicellular and don't have a nucleus with a membrane. However, human skin cells have both a membrane and are not unicellular.
