Answers:
1. phylogeny
2. Convergent evolution
3. Analogy
4. monophyletic group
5. Shared derived characters
6. Molecular systematics
Explanation:
1. phylogeny
In biology, phylogeny has to do with the evolutionary history and relationships within individuals or groups of organisms
2. Convergent evolution
It is the independent evolution of likely features in species of seperates periods or epochs in time. It develops an analogous structures thatshow a look alike form or function but were absent in the previous common ancestor of those groups
3. Analogy
It deals with similarity of function and superficial appearance of body form that have possess distinct origins. E.g. the wings of a fly, a moth, and a bird are analogous since they are formed independently as adaptations to a perform an activity—flying
4. monophyletic group
It is made up of all the descendants of a common ancestor. It distinctly has shared derived characteristics, which groups species in the clade from other species
5. Shared derived characters
A shared character is the similarities between two lineages , and a derived character is the evolved in the lineage that forms and distinguishes a clade. Shared derived characters is employed to classify organisms into clades
6. Molecular systematics
This employs molecular genetics to obsereve the evolution of relationships between organisms. It gives knowledge into the organisms history and how its evolution could have formed diversity among organisms.
